How to disassemble a bicycle fork forward

How to disassemble a bicycle suspension fork

After we have removed the suspension fork from the bike, old used grease should be removed from all of the above components, namely the bearings, cups and raceways, as well as the steering tube and other areas. It’s not worth applying a new one yet, we will add it back to the glass at the stage of installing the plug.

Next, let’s start disassembling the shock absorber for further lubrication replacement.

  • Turn the fork over and unscrew the mounting bolts.
    disassemble, bicycle, fork
  • We remove the pants from the legs of the fork. If necessary, remove the oil seals.
  • We remove used lubricant from all accessible surfaces. This procedure can be left for later and performed after complete disassembly, but it is preferable to do it right away in order to avoid oily marks on clothes, tools, etc. Do not forget to remove dirt and grease from the cuffs of the bicycle fork, as well as from the inside of the pants themselves.
  • Then remove the lower travel stops and stop stops. To do this, we apply a little effort and pull them off the rods.
  • We unscrew the adjustments on each of the fork legs. They are unscrewed using a special key, which, unfortunately, we did not have. Therefore, we had to make our own self-made key for these cases. We will attach a photo below, suddenly someone will come in handy. We take out the springs with caps and elastomers, as well as two rods (one from each leg).
  • Removing old grease from all fork surfaces.

This completes the process of disassembling the bicycle fork shock absorber. Next, apply new grease. What can be used as a lubricant, we will consider below.

How to assemble and put the plug back

The process of assembling and installing a bicycle suspension fork is carried out in the reverse order. The only thing that you should carefully and carefully perform this operation in order to avoid incorrect installation of components. After you have installed the assembled fork back on the bike, secured the stem, be sure to check that there is no play in the steering tube in the frame glass. If they are observed, then be sure to eliminate them before the trip.

After you set everything up and start riding, the first time there will be an abundant release of grease through the cuffs of the bike fork pants. Don’t worry, this is normal. Over time, excess oil will be squeezed out, and this process will stop. During this period, do not be lazy, and do not forget to wash off excess lubricant after each trip.

Step-by-step instruction

Before proceeding with disassembly and removal, it is necessary to set the bike with the wheels upwards, while the position of the bike must be stable.

Now you can start disassembling:

  • To release the rim brakes, first of all, the clamping bow must be folded back.
  • Removing a wheel with brake discs.
  • Removing the wings.
  • The bike must be turned over and installed on wheels.
  • Removing the handlebar with a stem by releasing the side bolts.
  • Removing the steering tube by unscrewing the anchor bolt mounts.
  • Removing the steering tube from the fork. Additionally, it will be necessary to clean the tube with a rag.
  • The fixing metal washer, located above the glass, is removed with a screwdriver or a thin knife. You need to pry the part very carefully.
  • The sealing gasket under the washer is pressed out using the same tools (screwdriver, knife) until the ring moves away from the edge of the glass.
  • Removing the rings with your hands.
  • Lifting the frame, it is necessary to carefully remove the fork from the bottom so that you do not have to later collect the bearings all over the floor.
  • Using a hammer and a screwdriver, the connecting ring is carefully knocked out, on which the steering column bearing lies, after which the crown is separated from the stem.
  • Plug removed.

This step-by-step guide will only apply to shock-absorbing bike models.

After the plug is removed, you can start disassembling it:

  • Using a hex key, the lower mounting bolts are unscrewed and the bolt is unscrewed, which is responsible for fastening the spring.
  • Elastomer limiting the spring is being removed.
  • To remove the oil seals and drain the used oil, it is necessary to unscrew the bolts and remove the pants. You should carefully consider what exactly will flow out of them. water, dirt or oil.
  • Removing anthers from the pants (you need a screwdriver) and bashings, which are removed only by turning around the axial.
  • All parts and mechanisms are inspected for damage. cracks and deformation, followed by washing in kerosene.
  • Spring lubrication work is in progress. It is better to choose a thick lubricant.

After completing all these simple steps, you can start collecting the plug.

When do you need to remove the fork from the bike??

Absolutely all mobile mechanisms of a bicycle need timely maintenance.

Removing the bike fork will be necessary in the following cases:

  • If you need to completely replace the old mechanism with a new one.
  • If it is necessary to replace bearings with support cups (possibly without them) or oil seals.
  • Apply new grease if necessary.
  • If necessary to align the steering tube.

The main symptoms of plug replacement are manifested in the occurrence of some extraneous sounds or in case of improper performance of their functions by some mechanisms:

  • extraneous knock or creak when moving;
  • insertion of the fork into the wedge, which does not allow for adjustment;
  • the steering wheel begins to turn, while making its course heavier;
  • legs and pants have characteristic damage (cracks).

How to remove the plug

Let’s look at the step-by-step process of dismantling a bicycle fork:

First you need to unscrew all the parts that are attached to the plug. These elements can be brake calipers or disc brake lines.

V-brakes are also removable. The bolts that fix the stem on the handlebar tube are unscrewed, after which it is necessary to unscrew the anchor bolt of the bicycle fork

Then you need to carefully remove the steering wheel. You should be extremely careful not to damage the hose lines.

The next step is to remove the spacer rings and the guide sleeve

In order to perform this procedure, carefully pry the sleeve in the area of ​​the cut using a flat screwdriver. Further, the upper rolling ring and the upper bearing are detached

The steering tube can now be removed. Then you need to get the bearing, rolling ring, and also detach the front wheel of the bicycle. To do this, unscrew the fixing bolts. The result is an unscrewed bicycle fork.

HOW WILL THE BIKE GEOMETRY CHANGE WHEN REPLACING THE FORK

The following point is worth noting. The larger the value of this angle, the closer to the vertical plane the fork feathers are, the higher the acceleration speed of the bike, and the better the fork works out all kinds of small bumps and bumps on the road. And, accordingly, if the angle decreases, the fork feathers will become flatter in relation to the surface (sharper), as a result, controllability and dynamics deteriorate, but at the same time, the fork begins to more easily transfer large bumps and potholes, and they, in to a lesser extent affect the movement of the bike.

For cross-country bicycles, the head angle is most often from 71 to 69 degrees, and the distance between the wheel axles is from 100 to 107 cm, and in DH, the angle is approximately 64 65 degrees, and the wheelbase length is 110 117 cm. table). A low inclination of the front fork paired with long stays, which is quite often used in bicycle choppers, leads to a significant deterioration in the bicycle‘s maneuverability, sharpness (efficiency) of control, an increase in the minimum possible bend radius and forces the handlebars to turn to a higher angle.

Disassembly and assembly of the plug

Once you understand the structure, you can start disassembling the front shock absorber of your bike. To do this, you need to stock up on tools, without which it will be impossible to carry out it: a set of pliers, a screwdriver, sliding and wrenches and a heap of rags. You can work with gloves so as not to get scratched.

There should be no difficulty in removing the front fork. There are only 2 types of their fastening: threaded and unthreaded. The second type is now standard, when using it, the stem holds the bearing, and the expanding tube (anchor) enters the steering tube of the fork and is fixed with two screws. They need to be unscrewed to remove the plug. It’s simple.

Those who in childhood were the happy owner of a bicycle remember the threaded mounts very well. In them, the upper bearing is clamped with a nut, a cone, a washer with a mustache and a locknut. This design can be removed very simply, it is even simpler than threadless forks, but it quickly gets loose when traveling.

The first step in removing the threaded fork is to place the bike on a flat surface and select a wrench for the bolt that connects the fork to the handlebar. Next, this bolt is unscrewed (don’t be alarmed. it is quite long) from the flare nut in the top tube. Now you need to loosen the steering wheel a little and take it out.

The next step is to remove the bearing. Most likely, it will be completely unusable and will need to be replaced. You can now remove the fork from the frame itself. There is another bearing under it, it must also be removed.

At the finish line, you need to unscrew the bolt holding the wing of the bicycle wheel at the top (usually it is located on the bicycle frame cylinder). The bolts securing the bike fender holder must also be unscrewed. Further, the wing is removed, the fork is released from the fastenings to the wheel (here you need to loosen the nuts) and disassembly ends there.

Now you should inspect the fork, change the bearings, thoroughly rinse everything with kerosene, lubricate with lithol and put everything back together. The assembly takes place in the reverse order and will not cause difficulties.

Fork maintenance

We clean

All anthers, casings and pipe surfaces that work while driving must be clean, therefore we constantly check and put them in order. Dirt on the insulation gradually leads to damage, and through them contamination of the internal mechanism already begins with subsequent breakdown.

When cleaning, it is important to note the following: if oil is used in the fork mechanism, it should never be exposed to the outside. If oil leaks are visible, the front fork needs to be repaired urgently. Further operation, most likely, will lead to breakage and complete replacement.

Further operation, most likely, will lead to breakage and complete replacement.

How is the rear shock absorber?

The rear shock absorber is a spring (spring) and a damper. in fact, the device that dampens rolling and vibrations. It looks like an oil or air cartridge, depending on the type.

The rear shock absorber is responsible for minimizing stress on your spine while riding over rough terrain. The level and quality of the damper, as well as its price, depend precisely on its ability to damp. that is, to absorb.

The process of disassembling and removing the rear shock is similar to disassembling the front forks.

We turn the bike over, we begin to remove the wheel. We unscrew the threaded locking wheel and see that there is a rear sprocket. a ratchet or a cassette, depending on the type. Most likely you have cassette hubs.

Removing the fork from a Beach Cruiser Bicycle

The main challenge is to carefully and carefully remove the sprocket and bushing. After that, you can safely remove the rear shock absorber

However, if you remove the rear shock absorber not for the purpose of prevention, but for the purpose of repair, and you want, for example, to eliminate the squeak or rattle, then you are unlikely to find the reason and you will have to contact the service in any case.

Remember, you can always entrust the repair and maintenance of the front spring forks to a professional. They will help you disassemble and lubricate the bike forks.

But, for example, the very maintenance of a bicycle’s front spring-loaded shock absorber is a process that is important to understand for anyone who cares about their two-wheeled vehicle.

DIY bike repair. video instructions will help you complete any task.

Fork repair and disassembly process

Manipulations to completely change oil, seals or oil seals and to eliminate breakdowns require complete or selective disassembly of the front fork. This procedure is performed as follows:

  • set the bike down with the saddle, release the brake, remove the front wheel, handlebar with stem and tube;
  • remove the plug, while it is necessary not to loose the balls of the bearings. Use a sharp object to remove the stem ring.

On the spring-elastomer design, we will try to understand in what sequence the fork should be disassembled:

  • Unscrew the lower fixing bolts using the hexagon socket.
  • Unscrew the bolt coordinating the force of the spring, remembering its stroke.
  • Pull out the elastomer, if necessary, change its value by simply cutting off the excess.
  • Unscrew the bolts and remove the pants, from which, with a screwdriver, remove the anthers and bosses, rotating them clockwise.

Then all elements should be examined for defects and washed in kerosene. Parts that require lubrication must be treated with a suitable agent. Experts recommend lubricating the spring with a thick product. this will make the fork work more efficiently. The assembly procedure is exactly the opposite and does not require additional explanation. The replacement of a shock absorbed bicycle fork should be entrusted to a person who specializes in such work, or to carry out this procedure in full accordance with his recommendations.

Experienced cyclists can repair the fork with their own hands, because in the process of using a person interested in the device of his vehicle gradually memorizes the names and functions of the elements, and therefore it will not be difficult for him to detect the problem and fix it. Those who have recently become the owner of this type of transport and have not yet acquired the necessary skills and knowledge should seek help from an experienced master.

Removing the fork from a bike?

To remove the fork from the bike for subsequent maintenance or complete replacement, it is necessary to turn the bike upside down, release the brake (if it is a rim brake) and remove the front wheel. At the second stage, the steering wheel with the stem is removed, then the steering tube.

After that, we remove the plug, it is extremely important not to lose the balls from the bearings. Then the support tapered ring is removed from the fork stem (usually using a sharp measure, gently squeezing it from all sides). Then we have a plug ready for service.

Individual users are advised to sort out even new, just purchased forks, explaining this by the need for individual debugging of the element.

How to disassemble a bicycle fork (using the example of a spring-electric fork) read below:

    it is necessary to unscrew the lower mounting bolts using hexagons;

Preload spring force adjusting bolt.

This completes the fork disassembly process and begins the process of caring for the parts received: a thorough inspection of the elements for damage, cracks and other things is necessary, thoroughly rinse with kerosene and lubricate the elements that need it. It is important to lubricate the springs with heavy grease for best fork performance.

Bicycle fork: remove, disassemble, assemble, install

It would seem, why do bicycles and cyclists need a suspension fork? But for both, it is extremely useful: a well-matched and adjusted fork can significantly reduce the load on the palms and hands while riding, improve the handling of the bike, and in addition, increases the service life of the frame and steering bearings by reducing the vibration effect. With proper care, the life of the plug can be extended several times. This will surely please the zealous owner of a two-wheeled friend, given the high cost of bicycle forks.

  • cleaning and lubricating the feet on the oil seals. every 100-150 km of the distance traveled;
  • inspection for cracks in the pants of the fork, lubrication of oil seals with disassembly. every 500-1000 km;
  • for oil forks. oil changes annually or after 4000-5000 km of travel.

Among the tools necessary for working with a bicycle fork are a screwdriver, pliers, a wrench, a small adjustable gas wrench. taking into account the specifics of working with oil, it is advised to stock up on rags or rags, in addition, work can be performed with gloves to protect hands from damage and pollution.

Taking care of your fork is the key to its health

Bicycle fork should be lubricated once a season, but with heavy use this procedure may be necessary more often. The process of lubricating a spring-elastomer fork is extremely simple: oil is poured with a syringe under the boot, then the fork is developed, and the remaining lubricant is removed with a soft cloth. Teflon grease is best applied to the feet near the oil seals (aerosol grease is increasingly being used).

Among the best lubricants, masters call silicone and transparent greases.

It is equally important to keep the forks clean: be sure to wipe the legs of the forks near the boots after each bike ride to avoid dirt getting into the oil and impairing the proper functioning of the bike.

Adjusting the bike fork begins with setting the sag, then rebound (if its adjustment is provided), under which the low-speed and high-speed compression will be adjusted. Experts note that the adjustment should be carried out in stages: you made one change. you checked the progress of the bike with a walk, only then change the next parameter. If you do not adhere to this recommendation, then the owner risks missing out on the difference in travel and lubricating the effect of the fork adjustment.

TIP! You need to start the fork adjustment process from the neutral position: half set rebound, compression arrows unscrewed completely counterclockwise.

Is it worth it to repair a bicycle fork yourself??

Of course, without the appropriate experience and skills in repairing bicycles, it is better not to take risks and turn to competent specialists. But over time, every cyclist who is more or less interested in his vehicle begins to understand the intricacies, remember the name of the parts and their functions, and feel the root of the problems. Therefore, over time, even such a difficult thing as repairing a plug can become an easy procedure.

Difficulties may arise due to the design features of the fork itself or its breakage.

As a rule, the owners are divided into two types: some prefer to ride a bike until all systems fail and it will be impossible to save such a patient, others carefully monitor the condition of the bike and prevent any breakdowns.

How to assemble a bike fork?

The assembly of the plug takes place in the reverse order of the parsing process and it is impractical to describe it additionally. The main thing is to carefully follow the order of the described procedures.

How to replace a fork on a bicycle?

It is not recommended for an untrained and inexperienced user to carry out: if it is possible to cope with simple care, then it is better to leave such a procedure to a qualified specialist. As a last resort, carry out the replacement under the supervision of the master, following his recommendations.

How to remove, disassemble and lubricate a bicycle fork

With the advent of your two-wheeled friend, life is filled not only with bright moments of walks in the park or long trips out of town with friends, but also with routine bike care. One can hear objections: they say that qualified specialists who understand what and what is in a complex bicycle device should be engaged in repair and maintenance. But besides this, you need to understand that this vehicle will require constant care and attention. Well, do not run to the master every week to lubricate the fork or check the rear shock absorber? There are a lot of little things in bicycle maintenance, which are best done by yourself: not only reliably, but also cheaply.

How to Disassemble a Road Bike Fork

First, you will need to remove the plug:

  • Dismantling the brake caliper, disc brake hydraulic lines, fenders. If a V-brake is installed, then it must also be dismantled, just like the speed sensor directed from the bike computer.
  • The bolts fixing the stem of the steering tube and the anchor of the fork must be removed.
  • The stem is neatly removed. This action is carried out with great care so as not to damage the hose.
  • Removing the spacer rings and guide cone (sleeve). A screwdriver is carefully inserted into the cuts, and the rings, one after the other, pry off.
  • The upper rolling ring with the upper bearing must be removed.
  • It is necessary to remove the steering tube from the glass.
  • By loosening the eccentric or unscrewing the fixing bolts, it will be possible to further remove the bearing with the removal of the lower rolling ring.
  • Removing the front wheel.
  • Plug removed.

After all mechanisms (bearings, cups, steering tube, rolling rings) have been removed, they must be cleaned of old grease with a rag. The parts will be treated with new grease during installation.

Now you can start disassembling the suspension fork itself:

  • The fork must be turned over and the bolts of its fastening must be unscrewed.
  • The legs of the fork must be freed from the pants and the oil seals must be removed.
  • Used grease should be removed from all visible and easily accessible surfaces of parts, including fork cuffs and pants themselves.
  • With little effort, the lower travel stops and stops of the stops themselves are pulled from the rods.
  • At each fork leg, it will be necessary to unscrew the adjustment. An adjustable wrench is useful for this.
  • The springs are removed along with the caps and elastomers, after which it is necessary to get the rods located in each leg.
  • It is necessary to remove the old grease coating from the surface of all parts of the fork.

Now you can start to renew the lubricant.

How and how can you lubricate a bicycle suspension fork?

The most popular lubricant for parts and mechanisms is Litol-24.

The main indicator in it is resistance to absolutely critical temperature conditions. The lubricant is not capable of thickening both at low negative (minus fifty degrees) and at high positive (plus one hundred and fifty degrees) temperature indicators.

SACHS PRIOR ENDMONTAGE | Sigg vs. Pulver

It is necessary to lubricate all parts and mechanisms with special care, but excessive effort will not be justified.

Parts and mechanisms that need lubrication:

  • spring;
  • cuff grooves;
  • trousers;
  • parts rubbing during operation. cups, bearings and rings.

Removing the fork from a bike?

To remove the fork from the bike, it is necessary to carry out a number of preparatory measures.

Dismantling and replacing a bicycle suspension fork

Not only the long service life of the bicycle, but also the safety of the cyclist itself depends on the proper condition of all components and mechanisms. Today’s publication will be devoted to one of the important details. a bicycle fork, about the methods and methods of its repair and installation.

How to assemble and put the fork back on the bike?

There is nothing new in the instructions for assembling and setting the fork. you will have to be guided by step-by-step instructions for disassembling and removing, only in the reverse order.

After installation, a prerequisite is to check that there is no play in the steering tube in the frame glass. If during the operation of the bike there is a release of lubricant from the cuffs, then you should not be afraid.

These are surpluses that will stop appearing over time. During this period, you will have to wipe your iron horse with special care after each bike ride.
