How to lubricate a bicycle rear wheel hub

Front fork damping system

It is the presence of a shock absorber that allows the biker not to pay attention to obstacles and makes the bike passable. A good shock absorber resists the reaction of the support to the front wheel in a timely manner, so the fork must be kept in good condition.

Normally, it is necessary to lubricate the fork legs after 150-200 kilometers, after 700 km (on average) the oil seals are disassembled and lubricated, and annually or after a run of 3-4 thousand km. the oil in the shock absorber is completely replaced.

It is better to show all the care of the fork in the video than to describe it in detail in text. For example, here you can see all the preventive maintenance operations for the front fork and shock absorbers:

Front and rear derailleurs

The continuity of the cycle depends on the clarity and consistency of their actions. Sometimes, especially when going uphill, switching should be done immediately after the afterburner, in order to change gears not in tension, but in free speed. This often takes a fraction of a second, and the switches must be flawlessly engaged so that the upward climb does not get bogged down.

Switches are ideally disassembled for lubrication. information about maintenance and lubrication can be found here:

How to properly lubricate a mountain bike?

A bicycle is one of such human mechanical inventions, in which there are elements that interact with each other by rolling some surfaces relative to others (wheel hubs, main carriage), by means of a chain transmission and by entering one smaller cylindrical surface into another. this is the damping mechanism front fork.

Despite the fact that bearings significantly reduce friction, proper lubrication of all these elements is necessary: ​​friction is reduced, movement is facilitated. This increases the life of the parts. However, it is important to know how to lubricate your bike properly.

The better the bike, the better the factory lubricant, the longer it lasts. These mountain bike models include, for example, Merida, GT. For example, it is known that the 2009 GT Avalanche 2.0 can freely gain 10,000 km without any lubrication of the bushings and carriages, while there is no damage to the bearings. Of course, this does not mean that you should not give a damn about the maintenance of the bike.

In the event that you buy an Auchan bike, it will be correct to open all the units that need lubrication immediately after purchase, check them and lubricate them again. Sometimes you need to replace something right away, for example, the rear bushing and bearings of the main carriage.

Probably it is not necessary to additionally indicate that only a thoroughly washed and, most importantly, dried bike should be lubricated.

So which parts of the bike need lubrication and how is it done?

The ride comfort depends on the regular lubrication of the bicycle chain. the chain does not buzz, it switches easily and freely. As a rule, the need for lubrication arises if the chain begins to rustle, rattle, and it is also difficult to shift gears. This can be felt after intensive driving in rain and muddy weather, after the chain is dry.

Main run carriage

We can say that this is the main axis of the bicycle. It is from her that an impulse is distributed to other elements. Therefore, the speed, ease, and comfort of the stroke depend on the state of the carriage. The carriage elements are:

  • cups,
  • actual axis,
  • bearings.

A different, thick grease is put into the carriage, not the kind that drips onto the chain or cables.

lubricate, bicycle, rear, wheel

Wheel axle bearings

If the grease has dried out, then there is resistance to the wheel movement, an increased noise level, and when the bearing is destroyed, a backlash occurs in the wheel, and even wheel jamming can occur. The bearing lubrication scheme is identical to that of the carriage bearings.

Chain tensioning mechanism

Rear derailleur rollers. They are often clogged with grease and dirt deposits that have thickened around the perimeter. They must be removed carefully, for example with a flat head screwdriver.

It is necessary to apply a dotted liquid lubricant on the roller axles to avoid squeaking and tight rotation. Only lubricated, they are able to keep the chain taut.

How to lubricate the carriage

Lubrication of the carriage on a bicycle is done by simply placing grease in the cups and on the surface of the bearings, on the bushing, and by distributing them evenly. In addition, before lubricating the carriage, it is advisable to thoroughly wash the bearings and all cavities, the surface of the bushing, for example, with kerosene. It is flushing that will subsequently make it possible to properly lubricate the carriage.

Wire ropes

The bike has several cables that transmit the force from the shifters and brake levers to the front and rear derailleurs, as well as to the disc brakes or V. brake. If dirt has accumulated between the jacket and the cable, or the surfaces are dry, the controls may become seized. This leads to untimely gear changes and even to the impossibility of emergency braking.

To lubricate the cable entry and exit points from the jacket, apply a couple of drops of lubricant, and then operate the shifter lever or the brake handle. This allows you to lubricate evenly and to a considerable depth.

How to lubricate a bicycle chain

  • increase the chain tension by moving it to the corresponding large sprockets;
  • carefully clean the chain from dirt, you can use a rag by pressing it against the free section of the bicycle chain and turning the pedal;
  • then we lubricate the chain, it is better to apply the lubricant over the top point of the roller (if the bike is standing with its wheels up). Make sure one drop falls on each link.
  • When the whole chain is lubricated, you need to intensively turn the pedals in the opposite direction for a minute. idling of the chain, and then, choosing an average speed, turn the bicycle chain in the forward direction.
  • At the final stage, you need to remove all excess oil from the outside with a soft clean rag, since the main action of the lubricant is to work on the inner joints of the links, and from the outside, ordinary grease clings to dust, poplar fluff and contaminates the rollers and rear sprockets with its deposits. So don’t be afraid to rub the chain properly.

In addition to lubrication, you need to monitor the mileage of the chain. On average, it needs to be replaced after every 1500. 2000 km for the following reasons:

Also, the question often arises about how often to lubricate the chain.?

There are no uniform standards. It all depends on the feelings of the bike owner:

  • if resistance or crunch appears in the circuit;
  • after driving through dust and sand;
  • after any walk that exceeds 3-5 hours.

Some people lubricate the chain after 100 km of run, regardless of operating conditions. Probably this decision is the most correct, as it teaches you to regular maintenance.

How to lubricate the carriage

Lubrication of the carriage on a bicycle is done by simply placing grease in the cups and on the surface of the bearings, on the bushing, and by distributing them evenly. In addition, before lubricating the carriage, it is advisable to thoroughly wash the bearings and all cavities, the surface of the bushing, for example, with kerosene. It is flushing that will subsequently make it possible to properly lubricate the carriage.

When to service the rear hub

Trouble-free operation of wheels, 100% serviceability of critical parts of the machine are possible only if they are maintained in proper condition. Lubricate the rear hub of the bike regularly as it visually dries. The spokes and rim must be tightened periodically. Bearing balls should also be changed, brake pads should be adjusted as often as possible.

The rear hub just needs to be serviced regularly. If you do not do this, very soon you will need a complex and expensive repair of the entire wheel. It’s better to take care of your vehicle right away for the long term. The rear hub does not require much more effort to service than the front.

It must be serviced in the following situations:

  • The body makes noise when rocking or while driving.
  • Backlash.
  • Bearing crunch.
  • Roll-forward dynamics is insufficient.

It is dangerous to ignore these signs. In the future, the bicycle disease will worsen. Very soon, the whole car would just crumble. A complete renovation will cost much more.

It is best to service the wheels regularly, especially since it is easy to do it yourself. In the spring, when the cycling season is just beginning, they should be checked for play. All bearings must not be over-tightened.

Causes of malfunctions

There can be a lot of reasons for bike wheel breakage. A short list of situations in which a malfunction may occur:

  • Bushings were not regularly serviced.
  • Excessive play.
  • Poor bushing elements.
  • Strong wear.
  • High tightening torque of the cone.

For long-term trouble-free operation of the bike, you must pay maximum attention to it. Maintenance every day, after each trip, regular inspection of all units and mechanisms will significantly extend the life of your two-wheeled friend. And then all open spaces will obey you. Drive with pleasure!

About the types of lubricants

Greases with an increased m of any element. such as lithium or calcium.

Lithium greased. such as Litol-24, it is good to lubricate the bearing axles, the carriage. It is lithium that gives the lubricant a specific slip, and it exhibits antifriction properties. In addition, lubricants with the addition of lithium do not thicken in frost up to 50 degrees and do not liquefy even at midday temperature in the desert, since they are capable of not changing their properties when heated to 150 degrees. The negative side is a fairly high water solubility, therefore, the lubrication points must be sealed with sealed anthers. In addition, this lubricant is not recommended to be applied to aluminum surfaces.

Calcium greases are greases and work well for a long time. An example of such a lubricant is Uniol. Unlike lithium, they have high adhesion, or adhesion to the surface, and hold for a long time. In addition, they help to resist corrosion in wet conditions. These lubricants are yellow or greenish. It is very important that they do not react with aluminum, unlike lithium greases. Therefore, their price is high and they can be used to lubricate expensive bikes.

Aerosols are a special type of lubricant. which can contain several components, for example Teflon. Their advantage is the ability to penetrate into hidden cavities and hard-to-reach places, including due to adhesion and surface tension. Their predecessor is kerosene, which has a truly unmatched enveloping ability, even able to get out of the vessel. With the help of such lubricants, it is possible to process cables, all types of threads, especially when loosening heavy and stuck connections. Examples of such lubricants are LM 40, LM 47 and others.

Perhaps the most famous quick-acting aerosol lubricant is the well-known WD-40. Among other things, it creates a hydrophobic layer and displaces water.

Lubricants with m silicone. Easy to apply, dust and water repellent.

Wax lubricants: on the chain, for example, the coating can last for several months under dry conditions. But the wax is subsequently capable of falling off itself in the form of scales and flakes. If the bike is operated in water, mud, fords are crossed or riding occurs in spring or autumn, then you need to choose another lubricant, because the wax is not fluid and cannot effectively penetrate into the chain connections.

A bicycle is not an easy machine. Before you lubricate your bike, you need to know that, in addition to the places for lubrication, there are areas where lubrication is completely undesirable. These include wheel tires (accidental ingress of grease on large areas can lead to skidding and the impossibility of emergency braking), rims (in the case of using tick-type brakes), as well as brake discs and pads. In addition, if oil gets on the rubber chamber, it can begin to corrode the rubber, which will lead to its rupture for a considerable length.

How to lubricate

The ideal option is a Teflon compound. For example, Finish Line Premium Grease: very slippery and viscous. However, Teflon can be replaced with the usual Litol-24 or the consistency for the CV joints of the car.

What definitely doesn’t work is any liquid mixture:

  • Bicycle chain maintenance compound.
  • Car engine or transmission oil.
  • Spindle.

How to sort out the rear hub of a speed bike

The word bulkhead in full is relevant only for tapered products. The maximum that can be done in a support on a slip is to clean and lubricate the bearings, and without removing them.

The repair principle for the front and rear cone nut bearings is the same, although the design differences are obvious. A set of sprockets is installed at the back; another design of the anther on the side of the cassette. However, the backbone is completely identical: that in the back, in the front, on both sides, one cone-nut and one row of balls, laid in bulk.

So, the subject of discussion is mountain bike rear cone service. It can be ratcheted, like on entry-class bikes like the Stels or Forward, or cassette like on mid to high-end bikes. By the way, in the material on how to choose a mountain bike. we have figured out in detail the differences between these two designs. There is also a recommendation on which design should be preferred.

Instructions on how to lubricate the rear bicycle hub

The bicycle is recognized worldwide as the most healthy, lightweight and practical means of transportation. But its owner should definitely learn how to eliminate at least elementary malfunctions, especially if you are traveling on a difficult and long cycle route. Otherwise, your two-wheeled friend will cost you a tidy sum.

You can master shallow recovery with patience and observation. These qualities are extremely needed when disassembling units, lubricating, replacing worn parts. Often you have to service the wheels along with the rear hubs.

How to disassemble a planetary hub.

The bushing is on the frame, covered with road dirt. In order to remove the wheel with the planetary hub from the bike, first remove the Hebie Chainglider chain guard.

Shimano Planetary Hub Rear Derailleur.

The external gearshift mechanism is very easy to remove, you just need to unscrew the retaining ring in the opposite direction to the arrow (next to the yellow alignment dots).

How to Grease Bike Wheel Bearings

After removing the planetary hub wheel and gear, you will see a locknut, several gearshift components, and a retaining clip holding the rear sprocket in place. There is also a small plastic round cap which I forged with a screwdriver (I hold it in my hand).

By removing the rear sprocket, you can see how much dirt has accumulated behind it. You don’t have to worry about this dirt. even after cleaning it will form again after a short use.

Turn the sleeve over and see the plastic cover that protects the roller brake mount. Unscrew the large nut and pry off the plastic cover along with the aluminum cone.

Below it we find the roller brake mount and the top of the bearing cone. The grease is slightly mixed with water, but you don’t have to worry about it, since this is the outer part of the sleeve. You can clean the wheel and the outside of the hub a little. Nothing needs to be lubricated here, so as not to accidentally bring dirt into the mechanisms.

To remove the shell, unscrew the two nuts. With a light blow, you need to remove the internal mechanisms from the sleeve shell. Now you can see how well the hub is sealed, especially on the side opposite to the roller brake mount.

The internal mechanisms are still well lubricated, although not too much. No signs of corrosion or contamination.

The sleeve shell from the inside looks like it just arrived from the factory.

These pink grease spots appear to be from the manufacturing process, or maybe it’s a special Shimano mark that indicates that the hub is being repaired out of warranty. The rolling bearing has gaps where there are no rollers. I don’t even know why it might be required.

We wash away the contaminated grease from the outside and a little grease from the inside.

The grease has been removed. As you can see, the bushing is still in excellent condition.

Exploded view of Shimano Nexus 8 SG-8R31 planetary hub mechanism.

I lubricated all hub bearings with original Shimano planetary hub grease. I did not regret the lubrication. I applied as much as they recommended to me on the forum. It seems to me that in any case it is better to pour over than not to top up.

A few weeks later, after I felt a deterioration in the ride in seventh and eighth gears, rolling forward, I decided that I had added too much lubricant. So I again had to disassemble the bushing and remove two-thirds of the grease. After that, I subjectively felt a significant relief of pedaling at high speed.

Shimano XT rear hub service

After I assembled the bushing and skated it for a decent amount of time, I took it apart again and took this photo to show how the grease quickly got into the right places.

Shimano Nexus 8 Planetary Hub Disassembly and Lubrication

Let’s take a look at Shimano planetary hub lubrication. Although the bushing worked as well as on the first day after buying it, I thought in the end it would be okay if you disassemble it for the first time and lubricate the bearings for prevention.

Before disassembling the planetary hub, please note that I do not have much more knowledge of planetary hubs than the average cyclist, and I am not a qualified bike mechanic. Disassemble your expensive Shimano planetary hub at your own risk.

How to assemble a planetary hub.

Excess grease has appeared over the rubber o-ring, which shows how small the tolerances are in this bushing. This is striking, especially if you have ever disassembled a 1970s Sturmey Archers hub that had massive slits everywhere.

Turn the bushing over, insert the bearing race on the correct side (see photo) and lubricate it.

Reinstall the rear bearing cone with sufficient finger pressure. This should put the internal mechanisms back into place. Screw the necessary parts onto the cone’s own thread. Thanks to the taper’s own thread, the task is greatly simplified, whereas on many other sleeves you would have to twist them for a long time to a long thread.

Lubricate the back of the dust cap and put it back.

Lubricate the back of the second metal dust cap and install in the same way. Reinstall all gearshift components and secure them in place with the lock nut.

Next, install the rear sprocket, replace the gearshift mechanism. Line up the red dots in the line. Reinstall the yellow dot retaining ring.

Flip the hub over, lubricate the inside of the roller brake mount cover and slide it onto the hub.

Do the same for the metal cover and secure it with the large lock nut.

lubricate, bicycle, rear, wheel

After installing the hub to the frame, make sure that the yellow dots adjustment is not lost.

To align, turn the knob on the switch.

Gear shifting after lubrication has become more precise and easier, although even before lubrication it cannot be said that it was bad. In high gears (5.8), a slight buzz was observed in free motion, which disappeared after 50 kilometers. High gears have their own grip, and 1st gears. 4th gear is yours. Work is done.

And what to do if a bronze ratchet starts to scroll in the brake shoe?

Grandfather is great. He knows everyone will show. And also a blogger.

Cool! Old school! No stupid music! Thank you!

Thank you for the video! on my boot is pressed with an asterisk. I can not remove the boot of the small bearing. I would like to see how to properly lubricate the brake sleeve with oil

Really MASTER. For such people and money is not a pity

If the locknuts on the axle are of different thickness, then the thinner one should be placed on the side of the asterisks.?

… So how do you properly lubricate the rear wheel hub? )))

A very complex bushing. Chinese is much easier.

What happens if you put an old lock washer without a tooth?

Thanks for the great video, everything is detailed and clear.

thanks for the video, respect and respect to YOU

Great review. I will just disassemble this sleeve. There are a lot of small details, why? thanks for the info.

I can disassemble a complete PM pistol, but assemble this mechanism…. Damn I will collect and watch the video step by step))) thanks for the science, I replaced the pedals. I went through the old ones in reserve, I’ll go while hang up a new reflector)) I’ll take on the wheel later)))

Thank you very much for the informative and informative video.!

The boot from the side of the star, in my opinion, is better to install under the asterisk so it will be fixed) Thanks for the detailed review!

Show how to properly tighten the rear wheel to the frame so as not to warp the wheel

Thank you, you explained everything very clearly. Can you clarify the lubrication? As I understand it, we lubricate the insides with liquid grease. and we hammer the podzhipniki?

Very good and detailed! Thank you very much! One of these days I will deal with the rear axle. Tell me what, besides the bearings, do you need to lubricate with lithol? You need to oil the sprocket and lubricate the threaded connections or something else?

Who can you call on WhatsApp now, scrolls the axis, the star does not spin the wheel, urgently

Cool video, owned Stork and Ukraine, constantly twisted bushings, front, rear, transmission, bought a mountain bike, (Chinese with an inexpensive canopy) and there are no problems at all))) Everything is thoroughly washed, wiped, swept, and gently vibrated or burn…

I have a bike Ukraine, produced in 1965. Everything works fine, it just flies. Satisfied and not going to switch to Chinese bullshit!
