How to install a front fork on a bike

How to remove and install the plug. step by step instructions

The first step is to get rid of the front wheel. To do this, turn the bike upside down. Release rim brakes by swinging out the clamping bow. With the discs, you can immediately start removing the wheel. Wings and other devices are immediately removed.

We put the bike in its usual position. Now you need to pull out the steering wheel and remove the plug from the glass:

Completely unscrew the steering pin fasteners, or “anchor” bolt.

install, front, fork, bike

The steering wheel is carefully removed from the fork. You can immediately wipe the pipe with a soft cloth.

Use a thin sharp object (screwdriver or office knife) to pry the retaining metal washer over the glass.

Use the same tool to press out the gasket under the washer. As soon as the ring comes off the edge of the glass, gently pull it out with your hands.

Raise the frame and gently pull the fork out from below. Why? To avoid damaging or losing bearings.

Next, you need to separate the crown from the stem. To do this, it is necessary to knock out the connecting ring on which the steering column bearing rests.

Carefully use a thin sharp object and a hammer to separate the ring from the edge of the fork. This completes the removal process.

How to remove, disassemble and lubricate a bicycle fork

If you do not know how to remove and disassemble a mountain bike suspension fork for maintenance, repair or replacement, then this article will help you find out what you need for this, and how to do it at home. Also, such questions will be considered here: how and how to lubricate the front fork, the frequency of maintenance and other tips on this topic. All this will be presented in the form of detailed instructions with pictures for each action, as well as a video for disassembling a bicycle suspension fork. In this article, we will analyze the RST GILA 100 mm spring-elastomer fork with disc brake mountings.

How to disassemble a bicycle suspension fork?

To disassemble the forks from bikes equipped with shock absorption, you will need to take several other steps.

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 by one, are pushed 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:

How To Install Forks | MTB Maintenance

  • 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.
  • Waste grease should be removed from all visible and easily accessible surfaces of parts, including the cuffs of the fork and the “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.

Removing the fork from a bike?

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

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.
  • 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.

Replacing the bike fork. a detailed description of the process

A bicycle fork is the connecting link between the frame and the front wheel. However, this mechanism is assigned the function of a shock absorber, smoothing vibrations and reducing loads. During operation, the mechanism breaks down, so every owner of a two-wheeled vehicle should know how to replace a fork on a bicycle.

How to put the fork back on the bike

First, inspect the bearing ring. There should be no damage or broken edges on it. Otherwise, you will need to replace it (if an old plug is installed). Assembly sequence:

Put the ring on the joint of the fork with the steering column.

Cover it with an adjustable wrench from above.

Using a hammer, press in the ring evenly with soft blows on the jaws of the key. We hammer “by sound”: while he is deaf, we continue to press, sonorous. the ring has fallen into place.

Lubricate the surface of the stopper (grease. lithol-24, buksol or special composition).

How to cut and install a new bike fork

Place the bearing carefully with the balls facing up. You can also apply a little lubricant to it. A sealing washer must be placed under the bearing.

Carefully insert the stem into the glass and repeat all removal operations in the reverse order.

How to remove a bicycle fork

Below you will find detailed instructions for dismantling the front suspension fork with explanatory pictures.

  • First of all, we carry out preparatory work, namely, we unscrew everything that is attached to the plug. In our case, this is the brake caliper, as well as the front disc brake hose, which is clamped to the fork legs. If you have V-brakes installed, then dismantle them. This also applies to the speed sensor from the bike computer, front fender, etc.
  • Unscrew the bolts securing the stem to the steering tube, and then unscrew the bicycle fork anchor bolt.
  • Carefully remove the steering wheel together with the stem and lower it down. At this stage, you should act carefully so as not to damage the hydraulic lines or accidentally hitting the metal parts of the steering wheel on the frame, so as not to scratch the latter.
  • Remove the spacer rings and the guide sleeve (cone). To do this, carefully pry it with a small flat screwdriver in the area of ​​the cut. Then we take out the upper rolling ring and the upper bearing. All these actions are illustrated by the pictures below.
  • All operations have been completed and now you can carefully remove the steering tube from the glass. After that, it remains for us to get the bearing, the lower rolling ring and remove the front wheel. To do this, we loosen the eccentric or unscrew the fixing bolts (depending on the type of attachment). This completes the process of removing the bike fork.

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 and how can you lubricate a bicycle suspension fork

I use Litol-24 grease to lubricate all the components of the bicycle front fork, including both the shock absorber and the head tube bearings. It is believed that it negatively affects aluminum parts when moisture gets in. But using it for five seasons, no negative consequences were noticed. The advantages of this grease include good temperature resistance. It does not thicken both in severe frost up to 50 C, and in extreme heat (up to 150 C).

Many people advise pouring liquid machine oils, sewing machine oil, and others into their forks. Personally, in my experience, a deterioration in the operation of the fork shock absorber was noticed (jerks were observed during compression and rebound of the spring). And if liquid oils worked better, manufacturers would have filled them in initially, which they do not.

We figured out how to lubricate a bicycle fork. Next, let’s see how to do this. We apply grease to the spring with excess (we ram the lubricant between the spring rings), the excess will come out through the hole under the stem and, if there is an excess in the pants, it will be squeezed out through the stuffing box seals (but you shouldn’t overdo it either). We also apply grease to the grooves of the cuffs and add forks to the pants. We lubricate all rubbing parts with a thin layer.

Before installing the plug into the glass, do not forget to lubricate the bearings, rings and cups.

This completes the lubrication process and you can go back to assembling and installing the bicycle fork.

How to remove and disassemble the front bike fork

A bicycle fork serves more than just a link between the frame and the front wheel. On MTB models, it also acts as the main shock absorber, smoothing out vibrations, stress on the arms and a negative effect on the mechanisms and the frame. Like any mechanism, it requires periodic maintenance, adjustment and replacement of component parts. And all this will require removal and disassembly. Is it possible to disassemble the bike fork by yourself? Quite, it only takes a little time, a few simple tools and accuracy.
