Bicycle Rear Wheel Play How To Fix

Eliminating front wheel runout

Remove the front wheel. We disassemble it. We wipe and remove the old grease from the raceways of balls and bushings.

We put a new grease and fix 9 balls in it (if they are in bulk) or 7 cage bearings.

Next, we screw on the radius nut, after which we install it into the sleeve, screw on the radius nut from the opposite side. Then we align the ends of the threaded axle, remaining on both sides (they must be the same).

Bicycle Rear Wheel Play How To Fix

We tighten the locknuts by expanding them with a notch to the radius nuts. Then, with the introduction of the keys, it presses them tightly. It is important not to forget to set the correct tension of the bearings (balls) correctly. In no case should they be pinched, on the one hand, and such an extreme as the remaining wobble of the wheel, on the other, should not be allowed.

When assembling the front wheel, the radius and locknuts are first pressed from the side of the disc brake. Since it is inconvenient to do it from this side. The nuts are tightened with two keys. It is most convenient to use for the indicated purposes the Swedish key No. 1 and a special thin open-end wrench designed to perform just such operations. It is not difficult to buy them. But get the maximum Pull-up Possible.

We pass to the other side of the wheel. We also set the tension of the balls and tighten the nuts. When the lock nut is properly tightened, the radius nut begins to rotate with it.

But sometimes situations arise when the nuts are overtightened. In this case, they need to be slightly weakened. To do this, turn the radius nut counterclockwise (use a thin open-end wrench).
After setting the required tension, a control check is performed and the radius nut and lock nut are pressed.

Check the axle free play. The void gap formed between the “pants” and the locknut is filled by installing a washer of the required thickness, or one of the locknuts is changed (there are two of them on each side, of different thickness). Swap thick and thin nuts.
We install the assembled wheel in place and fix it with cap nuts. Checking the roll forward.

Factors leading to wheel runout

The main reasons for the appearance of backlash can be considered:

  • Significant wear of the installed sleeve;
  • Damage to radius nuts on the ball raceways.
  • Wear of Special cuts with a sufficiently high relief, which are applied at the factory to locknuts and contribute to a tighter contact of this product with the radius nut. Increased adhesion to the surface of the nuts Reduces the chance of loosening. Similar notches should be found on the main nuts that secure the wheel to the bike. In this situation, it is recommended to replace the nuts with new products.
  • The compression between the radius and locknut is relaxed. It is necessary to promptly tighten.
  • When installing a wheel on a bicycle, there is an empty space between the locknut and the rear stays (colloquially called “pants”), contributing to the runout. It is recommended to install a washer here, which will select the void.

How to fix wheel play on a bike

During operation, the wheel mount is loosened and play appears. Untimely elimination of the indicated malfunction can lead to the failure of the bike at the most inopportune moment.

We remove the backlash of the rear wheel

On the rear wheel, there is most often a hub for a ratchet, much less often for a cassette. Therefore, consider the first option.
The wheel is removed, disassembled, wiped, lubricated. Balls or bearings are installed. It is put in place with pre-screwed radius and locknuts.

The ratchet is removed. On the side where it is installed, the radius and locknut are tightened first. On the disc brake side. second. Do not forget to preset the tension of the bearings or balls.

When assembling, a situation often arises when the balls relax when the second pair of nuts is heavy. An assistant (“third hand”) is required. If not, you can use a bicycle frame as such.

We put the ratchet in place. Checking how easily it rotates. We fix it in place with a clamping nut. We carry out the assembly in the same way as the front wheel.

The need to remove the ratchet is due to the fact that without this it is impossible to service the bushing. Since otherwise it is impossible with the required force Preload the nuts, located just under it, and remove the radius nuts.

The voids when installing the wheel in place (in the “pants”) are also selected by installing a thick washer.

When installed, the wheel is pressed against the bicycle feather by a clamping nut (from the ratchet side) and is strongly pressed. Only after this operation does it become possible, without outside help, to set the correct tension of the balls and to properly clamp the radius and locknut both from the side of the brake disc and from the side of the ratchet.

After that, the wheel is fixed to the frame feather with two nuts, then it is checked for ease of rotation and the absence of backlash.

Curved rim

The appearance of irregularities on the rims indirectly can lead to several more problems listed in the list. Therefore, the repair of bicycle wheels is one of the most fundamental work, requiring timeliness and accuracy. The unevenness of the wheel has the following consequences:

  • Changing the tension in the needles. If a “figure eight” appears on the wheel on impact, the tension on the spokes on one side is weakened. This means that the wheel deforms and this leads to unnecessary stress on the hub bearings and earlier wheel failure.
  • A similar situation occurs during adjustments: on one side, the spokes will always be a little tighter to keep the rim straight, and this automatically increases the chance that the spoke will burst under natural stress. Accordingly, constant corrections of irregularities entail an eerie spread and imbalance in the spoke tension.
  • Riding on a curved rim affects not only the spokes but also the hubs. Their wear increases and the likelihood that a bicycle wheel hub repair will be required.

Among other things, acceleration and average speed will decrease on weak and worn spokes, as well as on a curved rim.

Maintenance of bicycle wheels includes rare breakdowns of various difficulties.

Wheel malfunctions

Most modern bicycles are assembled on tube wheels, so one of the most common and commonplace problems is puncture. Every cyclist should be able to cope with this task, but at first it is better to use the services of a workshop and observe the work of specialists.

If the repair of a puncture of a bicycle wheel with the necessary tools can be carried out in the field, then the rest of the problems have much more significant consequences and it will take more time, skills and tools to eliminate them. Let’s take a look at all of the most popular bicycle wheel problems:

  • Rim deformation: formation of “eight”, “eggs”;
  • Broken spoke;
  • Spokes wear, loss of elasticity;
  • Damaged front and rear hub bearings;
  • Rear ratchet hub axle curvature;
  • Eccentric bursting under pressure;
  • Wear of the teeth of the system While the rear wheel.

Our company has sufficient equipment, and we are ready to solve your problem if the repair of this breakdown is cheaper than a complete replacement of parts. The cost of work differs depending on the complexity of their implementation. For a better understanding, it is worth considering typical problems in detail.

How to fix wheel play on a bike

When a bicycle rear wheel hub repair is needed

Timely maintenance of the rear hub keeps the part in good condition. It is periodically necessary:

  • Tighten the body;
  • Replace worn bearing balls;
  • Lubricate all body parts directly from the inside;
  • Adjust the pads on the brake sleeve.

Dismantling the wheel itself is somewhat easier than disassembling and removing the sleeve body. There is a need to remove all parts from the spokes. Complete disassembly is required if the entire body needs to be replaced.

Although the wheels are an unpretentious part, they still sometimes require repair. Components need adjustment or replacement:

  • When the body creates a roar on the move and its shakiness, which is easy to identify with two fingers;
  • When there is wheel play while driving;
  • If we see bad rolling dynamics;
  • When a crunch is heard, indicating worn bearings.

Looseness and twisting of the rear hub housing is easy enough to deal with. You just need to tighten the fastening nuts. If they are tightly tightened (and this also occurs), the wheel is somewhat more difficult to rotate. It is therefore advisable to loosen the nuts. The poor condition of the bearings or the lack of lubrication are determined by the deterioration of rolling, the occurrence of extraneous sounds.

We disassemble the case, clean it and lubricate it

In order for the subsequent assembly of the wheel to take place, it is better to carry out repair work on the spoked bushing. Dismantling the brakeless bushing is carried out in several stages:

  • Removing the cassette with a puller or whip from the axial element.
  • Opening the circlip.
  • Removing washers and bulk bearings (industrial bearings). We put emphasis on their rightful place, so that then correctly assemble the parts.
  • Inspection of bearing damage. We replace worn-out elements with new analogs, suitable for further cleaning with a solvent from dirty impurities.
  • Removing the axle completely.
  • Cleaning the case from dirty impurities. Wipe each internal cavity with only a soft cloth.
  • Consistent lubrication of all parts. The sequence is very important for reverse installation. First, a small amount of grease is distributed over the walls of the housing. Bearings are impregnated somewhat more abundantly.
  • Finishing the whole process by installing the stopper and tightening the sleeve using the fastening nuts.

We begin to disassemble the rear hub, we remove the cassette retaining ring

We remove the inner ring of the bearing itself with two needle-nose pliers, while carefully pushing the “nose” directly into the spline groove of the outer circlip. We fix the stars well, as if turning them along the course of the free wheel. If the wheels have a right-hand thread, use the same method. Rotation of the bushing retaining ring should be counterclockwise.

The outer circlip has a right-hand thread. When working with a bicycle drivetrain, it is important to consider the direction of pedaling. Ideally, it should be consistent with the tightening direction. Therefore, the sleeve is unscrewed counterclockwise. When the transmission is located, the rear hub is equipped with a right-hand thread.

How to lubricate the bicycle hub

So, here is checked out. We study in what condition it is. Although its service life is identical to the working life of the wheel, it will not hurt to clean it from the accumulated dirt.

Wiping the inner space of the sleeve is done with a clean dry bandage, cotton wool or rag. Stubborn dirt Remove with a cloth soaked in gasoline. We turn to wiping the left cone, while checking the fastening of the right one (where the cassette stars are located). After the walls have dried, we start applying new grease.

As for the graphite grease, it has good performance. There is practically no adhesion of dirt, but the lubricant itself becomes significantly dirty. In addition, graphite grease has a moderate resource (500 km).

Features of a bike with a planetary hub

A very common variation of the transmission of a bicycle includes a planetary hub, equipped with a gear mechanism from the inside, which changes the gear ratio. The adjustment of the relative position and, directly, the engagement of the gears is carried out using the speed switch with the handle on the steering wheel. Due to its fundamental difference from the “star” transmission, this gearshift system is in good demand in the world of bicycles.

Planetary hub priorities

  • The chain has a straight course, and the leading and, accordingly, the driven stars have a very long service life. Externally, the transmission is identical to the transmission of a conventional single speed.
  • Protection against external influences on gear shifting is due to the secrecy of the mechanism. The service life of this mechanism significantly exceeds the permissible operating rate of cassettes and ratchets. In planetary bicycles, all gear ratios are allowed.
  • There is no need for constant maintenance of the device. Its damage is also unlikely.

Reverse side of the medal of planetary bushings

  • With their high friction and gear sensitivity, planetary bikes are NOT suitable for racing.
  • Sensation of weight gain. However, among planetary hubs, some three-speed counterparts weigh a little. up to 1 kg. When driving, the additional load on the wheel is quite noticeable.
  • Self-repair unlikely. To meet a service for the repair of planetary hubs is quite problematic. Due to the disposability of the planetary, repairs will not be cheap, it is more expedient to install a new analog.
  • Quite a high price. While the cost is well worth it, installing a new gearbox is not sustainable. The optimal solution is to buy a ready-made bike with her.

For a bicycle with planetary hubs, it is common for many kilometers to travel on mostly flat roads. It is good to have such a bicycle for a resident of a settlement with flat terrain or a large city with a developed road network. This drivetrain variation is ideal for frequent city commutes or if you don’t want to waste time on cassettes and chains.

We check the quality of the repair in practice. Using different speed settings, you need to test the bike. It is enough to listen to your feelings in order to understand whether there is a wheel play or not, whether it is firmly fixed. Correct renovation brings a sense of comfort and confidence in the future. With a frivolous attitude to work, secondary adjustment is inevitable.

Do-it-yourself repairs and maintenance of the rear hub is not difficult. If it is necessary to replace the entire structure, it is preferable to choose a model identical to the analogue that is now out of order. If you are not sure or able to repair the rear hub yourself, it is very wise to use the services of a specialist. Otherwise, there is a high probability of damage to the part itself.

Veloremont bicycle repair services

The rear hub experiences constant increased loads: it transfers torque from the pedals to the wheel, and the dynamic characteristics of the bike directly depend on its serviceability. The mechanism needs regular periodic maintenance, and in its absence, the parts fail faster. In our workshop, we repair the rear hub of a bicycle, which includes a complete bulkhead with replacement bearings, as well as troubleshooting and replacement of grease.

The most common rear hub problems are:

  • Backlash and chipping on the inner surface of the sleeve. The wizard will make adjustments and adjustments to establish the correct position.
  • Breakage and Curvature of the axis. This problem occurs more often with ratchet hubs, the defective bike part must be replaced.
  • The appearance of a crunch and other extraneous sounds. This indicates the ingress of dust and dirt into the lubricant, so it needs to be replaced urgently. Complete overhaul includes bearing replacement and new grease to minimize friction.

After the repair of the rear hub of the bicycle, the smoothness of the ride is restored, the installation of new high-quality parts will ensure long-term trouble-free use. Nearby repair of the bike by the specialists of our workshop in order to return it controllability and guarantee reliability.

Bicycle rear wheel play. causes and remedies

Cycling and cycling tourism are gaining more and more popularity. Many people switch to a bicycle instead of a car and have great pleasure.

However, during operation, there are also negative moments associated with malfunctions of various parts and mechanisms. One of the most common problems is wheel play. If untimely repairs, this can lead to the destruction of the bike.

We remove the backlash of the rear wheel

On the rear wheel, there is most often a hub for a ratchet, much less often for a cassette. Therefore, consider the first option.
The wheel is removed, disassembled, wiped, lubricated. Balls or bearings are installed. It is put in place with pre-screwed radius and locknuts.

The ratchet is removed. On the side where it is installed, the radius and locknut are tightened first. On the disc brake side. second. Do not forget to preset the tension of the bearings or balls.

When assembling, a situation often arises when the balls relax when the second pair of nuts is heavy. An assistant (“third hand”) is required. If not, you can use a bicycle frame as such.

We put the ratchet in place. Checking how easily it rotates. We fix it in place with a clamping nut. We carry out the assembly in the same way as the front wheel.

The need to remove the ratchet is due to the fact that without this it is impossible to service the bushing. Since otherwise it is impossible with the required force Preload the nuts, located just under it, and remove the radius nuts.

The voids when installing the wheel in place (in the “pants”) are also selected by installing a thick washer.

When installed, the wheel is pressed against the bicycle feather by a clamping nut (from the ratchet side) and is strongly pressed. Only after this operation does it become possible, without outside help, to set the correct tension of the balls and to properly clamp the radius and locknut both from the side of the brake disc and from the side of the ratchet.

After that, the wheel is fixed to the frame feather with two nuts, then it is checked for ease of rotation and the absence of backlash.

Eliminating front wheel runout

Remove the front wheel. We disassemble it. We wipe and remove the old grease from the raceways of balls and bushings.

We put a new grease and fix 9 balls in it (if they are in bulk) or 7 cage bearings.

Next, we screw on the radius nut, after which we install it into the sleeve, screw on the radius nut from the opposite side. Then we align the ends of the threaded axle, remaining on both sides (they must be the same).

We tighten the locknuts by expanding them with a notch to the radius nuts. Then, with the introduction of the keys, it presses them tightly. It is important not to forget to set the correct tension of the bearings (balls) correctly. In no case should they be pinched, on the one hand, and such an extreme as the remaining wobble of the wheel, on the other, should not be allowed.

It is most convenient to use for the indicated purposes the Swedish key No. 1 and a special thin open-end wrench designed to perform just such operations. It is not difficult to buy them. But get the maximum Pull-up Possible.

We pass to the other side of the wheel. We also set the tension of the balls and tighten the nuts. When the lock nut is properly tightened, the radius nut begins to rotate with it.

But sometimes situations arise when the nuts are overtightened. In this case, they need to be slightly weakened. To do this, turn the radius nut counterclockwise (use a thin open-end wrench).

Check the axle free play. The void gap formed between the “pants” and the locknut is filled by installing a washer of the required thickness, or one of the locknuts is changed (there are two of them on each side, of different thickness). Swap thick and thin nuts.
We install the assembled wheel in place and fix it with cap nuts. Checking the roll forward.

Rear wheel

  • First of all, remove the wheel. A ratchet is most often included in the rear hub design. It must also be removed first, since there is a cone and a lock nut under the ratchet. Otherwise, the sleeve will serve.
  • We disassemble the bushing and wipe all parts from old grease and dirt.
  • Looking through the radius nuts, raceways and the bearings themselves. If there is mechanical damage, we replace the worn part with a new one.
  • After checking, we put all the parts of the bushing in place, put in a new grease. We tighten radius and lock nuts.
  • We tighten the cone and the locknut from the side of the ratchet, and on the other side we adjust the tension of the bearings. The bearings often relax when the second pair of nuts is tightened. In order to avoid this, you can use the bike frame or call an assistant.
  • Install the ratchet in place. Check the ease of rotation, Fix.
  • The wheel is assembled, and now you need to install it on the frame. If there is a gap between the locknut and the frame, then it must be filled with a thick washer.
  • Presses the wheel with a clamping nut on the ratchet side. Now you need to check the correct bearing tension. After that, the wheel is clamped on the other side.
  • Check the ease of rolling and the presence of backlash. If everything is done correctly, the wheel will spin smoothly, and there will be no backlash.

Repairs

To eliminate the backlash or, on the contrary, tighten the cone, we need a pair of keys, usually a 15 mm open-end cone wrench and a 17 mm open-end cone. First, we need to loosen the locknut, then loosen or tighten the flare nut to the desired value, ideally there should be no backlash, then tighten the locknut again.

With a normally adjusted cone, the wheel should turn easily under the weight of a reflector or a nipple.

There is a moment when the hub of a bicycle wheel breaks or bends, most often this is due to NOT high-quality parts. In such cases, it is necessary to completely replace the hub axle with a new one of a higher quality. When replacing the axle of the hub, or when you need to do maintenance or repair the rear hub of the bicycle, for convenience, you can remove the ratchet, if you just need to tighten or loosen the cone, you can do without this action.

Twisted here of the rear wheel hubs.

In order for breakdowns to occur less often, it is necessary to do periodic maintenance, mainly adjusting the cone as well as washing, cleaning parts and lubricating the bearings, sometimes replacing bearings, seals or washers.

Causes of occurrence

The main reasons for backlash are the following:

  • Abrasion of the wheel hub;
  • Wear of the radius nut (differently cone) and damage to the bearing raceways;
  • Abrasion Special notches on the lock nut, which serve for a closer contact with the radius nut. The high degree of adhesion between the nuts prevents loosening;

Most often, these reasons arise during active use with extreme loads on the wheels and the bike as a whole. The service life and the quality of the parts are NOT less important.

The following causes can be eliminated without replacing parts:

  • Loosening of the compression between the radius and the locknut. Requires elementary Key pull:
  • The gap that appears after the wheel is in place between the bike frame and the locknut. It is necessary to fill the empty space with a washer or engraver;

Front wheel

There are slight differences in the design of the front and rear wheels, so let’s consider the front wheel in detail:

Wheel play is a common problem that occurs during bicycle operation. You can eliminate this malfunction manually, rather than resorting to the help of a specialist.

If a bicycle is used with this malfunction for a long time, the wheel may be completely damaged. Here, the cones and raceways inside the bushing are deformed. This will result in a complete replacement of the rim with the defective hub.

Bicycle rear hub repair

Rear hub failure is one of the main problems faced by bike owners. This is not surprising, because no matter how carefully the owner takes care of his “iron friend”, the rear hub will still be the most loaded part of the bike. In addition, the bearings in the bushings are often clogged with dirt and corroded.

For self-bulkhead and repair of the rear hub of a bicycle, you must have the appropriate knowledge and skills. The following will describe how to fix a broken rear hub, rather than resorting to the services of specialized service centers.

The most common problem with a bike rear hub is a loose or tight cone. In the first case, it signals a noticeable wheel play, and in the second. the crunch of bearings and the severity of the stroke. If both problems occur, it is necessary to immediately start troubleshooting.

How to fix wheel play on a bike

During operation, the wheel mount is loosened and play appears. Untimely elimination of the indicated malfunction can lead to the failure of the bike at the most inopportune moment.

How to remove backlash?

To eliminate backlash, first of all, it is necessary to determine the prerequisite for its appearance. To do this, remove the wheel, grab one end of the wasp and move it up and down. If wobbling is observed, take two keys (thin, open-end) and tighten the radius and lock nut from both sides.

Attention! Strong clamping will NOT allow the wheel to spin, weak clamping leads to backlash (clothing).

After adjusting the clamping, we check the presence of backlash, also grasping here. If the problem persists, disassemble the bushing completely and look inside for the cause.

The front and rear wheels of a bicycle are partially different in design, so we will consider them separately.

Rear vlulka maintenance. disassembly, prevention and assembly

For example, it happens that the bearings “eat away” in the housing of the rear bushing of the hole, possibly due to axle curvature or lack of lubrication. In this situation, the repair of the rear wheel of a bicycle consists in a complete replacement of the hub body or even the wheel itself. Therefore, so that this does not happen, it is necessary before each long-distance cycling trip to inspect your two-wheeled horse, and during troubleshooting.

What is backlash?

Classically, backlash is called a small gap between mechanical parts, which rotate together and are interconnected. Simply put, the free movement of one element, and not leading to movement of another element of the system.

Bicycle wheel play is some displacement of its plane with respect to the axis of rotation or hub, leading to a figure-eight movement.

Due to the backlash during the ride, the so-called wheel beating is felt. This phenomenon occurs when the wheel is displaced to the right or left in relation to the vertical axis of motion.

We remove the backlash of the rear wheel

On the rear wheel, there is most often a hub for a ratchet, much less often for a cassette. Therefore, consider the first option.
The wheel is removed, disassembled, wiped, lubricated. Balls or bearings are installed. It is put in place with pre-screwed radius and locknuts.

The ratchet is removed. On the side where it is installed, the radius and locknut are tightened first. On the disc brake side. second. Do not forget to preset the tension of the bearings or balls.

When assembling, a situation often arises when the balls relax when the second pair of nuts is heavy. An assistant (“third hand”) is required. If not, you can use a bicycle frame as such.

We put the ratchet in place. Checking how easily it rotates. We fix it in place with a clamping nut. We carry out the assembly in the same way as the front wheel.

The need to remove the ratchet is due to the fact that without this it is impossible to service the bushing. Since otherwise it is impossible with the required force Preload the nuts, located just under it, and remove the radius nuts.

The voids when installing the wheel in place (in the “pants”) are also selected by installing a thick washer.

When installed, the wheel is pressed against the bicycle feather by a clamping nut (from the ratchet side) and is strongly pressed. Only after this operation does it become possible, without outside help, to set the correct tension of the balls and to properly clamp the radius and locknut both from the side of the brake disc and from the side of the ratchet.

After that, the wheel is fixed to the frame feather with two nuts, then it is checked for ease of rotation and the absence of backlash.

Repairs

To eliminate the backlash or, on the contrary, tighten the cone, we need a pair of keys, usually a 15 mm open-end cone wrench and a 17 mm open-end cone. First, we need to loosen the locknut, then loosen or tighten the flare nut to the desired value, ideally there should be no backlash, then tighten the locknut again.

With a normally adjusted cone, the wheel should turn easily under the weight of a reflector or a nipple.

There is a moment when the hub of a bicycle wheel breaks or bends, most often this is due to NOT high-quality parts. In such cases, it is necessary to completely replace the hub axle with a new one of a higher quality. When replacing the axle of the hub, or when you need to do maintenance or repair the rear hub of the bicycle, for convenience, you can remove the ratchet, if you just need to tighten or loosen the cone, you can do without this action.

Twisted here of the rear wheel hubs.

In order for breakdowns to occur less often, it is necessary to do periodic maintenance, mainly adjusting the cone as well as washing, cleaning parts and lubricating the bearings, sometimes replacing bearings, seals or washers.

Causes of occurrence

The main reasons for backlash are the following:

  • Abrasion of the wheel hub;
  • Wear of the radius nut (differently cone) and damage to the bearing raceways;
  • Abrasion Special notches on the lock nut, which serve for a closer contact with the radius nut. The high degree of adhesion between the nuts prevents loosening;

Most often, these reasons arise during active use with extreme loads on the wheels and the bike as a whole. The service life and the quality of the parts are NOT less important.

The following causes can be eliminated without replacing parts:

  • Loosening of the compression between the radius and the locknut. Requires elementary Key pull:
  • The gap that appears after the wheel is in place between the bike frame and the locknut. It is necessary to fill the empty space with a washer or engraver;

Bicycle rear wheel play. causes and remedies

Cycling and cycling tourism are gaining more and more popularity. Many people switch to a bicycle instead of a car and have great pleasure.

However, during operation, there are also negative moments associated with malfunctions of various parts and mechanisms. One of the most common problems is wheel play. If untimely repairs, this can lead to the destruction of the bike.

Front wheel

There are slight differences in the design of the front and rear wheels, so let’s consider the front wheel in detail:

Wheel play is a common problem that occurs during bicycle operation. You can eliminate this malfunction manually, rather than resorting to the help of a specialist.

If a bicycle is used with this malfunction for a long time, the wheel may be completely damaged. Here, the cones and raceways inside the bushing are deformed. This will result in a complete replacement of the rim with the defective hub.

Rear wheel

  • First of all, remove the wheel. A ratchet is most often included in the rear hub design. It must also be removed first, since there is a cone and a lock nut under the ratchet. Otherwise, the sleeve will serve.
  • We disassemble the bushing and wipe all parts from old grease and dirt.
  • Looking through the radius nuts, raceways and the bearings themselves. If there is mechanical damage, we replace the worn part with a new one.
  • After checking, we put all the parts of the bushing in place, put in a new grease. We tighten radius and lock nuts.
  • We tighten the cone and the locknut from the side of the ratchet, and on the other side we adjust the tension of the bearings. The bearings often relax when the second pair of nuts is tightened. In order to avoid this, you can use the bike frame or call an assistant.
  • Install the ratchet in place. Check the ease of rotation, Fix.
  • The wheel is assembled, and now you need to install it on the frame. If there is a gap between the locknut and the frame, then it must be filled with a thick washer.
  • Presses the wheel with a clamping nut on the ratchet side. Now you need to check the correct bearing tension. After that, the wheel is clamped on the other side.
  • Check the ease of rolling and the presence of backlash. If everything is done correctly, the wheel will spin smoothly, and there will be no backlash.
