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.

Dismantling the fork on bicycles. for lubrication and repair

If you plan to replace the fork on your bike, skip this section.

Let’s take a quick look at the features of disassembling a bicycle suspension fork. Disassembly is needed in order to service the components of the mechanism, as well as replace them. The disassembly process looks like this:

  • Bolts are unscrewed at the bottom of the device.
  • After that, the pants are dismantled.
  • Any grease present must be removed from the pants, and the cavity of each tube must be cleaned.
  • Stops and stops are dismantled.
  • After disassembling the shock absorber, it should be cleaned of old grease and opened with a new one and replace the part if it is out of order.

Fork maintenance intervals

The frequency of changing the lubricant of a bicycle fork depends not least on the road surface on which you are riding. If there is an abundance of dust, mud, sand and other abrasive material on your routes, then the frequency of service should be increased. Here are the average figures after which maintenance should be performed.

Approximately every 700-800 km, the oil seals should be disassembled and lubricated, and every 4000-5000 km the entire fork is moved and lubricated.

How to remove a bicycle fork

Removing a bicycle fork is a process that should be done in a garage. It is possible to dismantle it in the field, but is it rational? To remove, you need to prepare the necessary tool, and only then perform each action, following the instructions:

  • Initially, you need to free the structure from third-party parts. To do this, unscrew all the parts screwed to the fork. the caliper, the fender (if any), the hydraulic line and the mechanical-type brake system, the bike computer. All parts that are attached to the fork must be removed.
  • The front wheel is dismantled.
  • The bolts that secure the stem of the steering tube are unscrewed. Then you also need to unscrew the fork armature bolt using a hex wrench.
  • Now remove the stem from the mountain bike and move it to the side. This must be done carefully so as not to damage the brake hose and not to scratch the paintwork of the parts.
  • The metal washer and plastic washer are dismantled. To remove these rings, you need to pry them with a screwdriver in the area where the cuts are located. Following them, the upper steering column bearing is removed.
  • The steering tube is slowly and carefully removed from the glass. The lower part also contains a bearing and a ring that must be removed.
  • The bike fork has been removed and you can start replacing it.

As you may have noticed, removing, disassembling and lubricating a mountain or city bike suspension fork at home is not that difficult. The main thing is to treat this process responsibly and do everything consistently. The better you take care of your iron horse, the longer it will delight you with its trouble-free work.

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 negative effects 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.

Why remove and disassemble the bike fork

A bicycle fork, like all other components, can be replaced, repaired or serviced. Therefore, before proceeding with these procedures, we need to remove it from the bike, and in some cases disassemble the shock absorber for parts. In what cases will we have to remove it? First of all, this is when it is replaced by another. Secondly, it may be necessary to replace bearings and / or support cups, apply new lubricant, and also, there are times when it is necessary to align the steering tube or perform other repair work.

Disassembling a fork shock absorber is most often necessary to replace lubricant or worn components. For example, these can be oil seals (cuffs), etc.

How and how can you lubricate a bicycle suspension fork

I use Litol-24 grease to lubricate all of the bike’s front fork assemblies, 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, there was a deterioration in the performance of the fork shock absorber (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 look at 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 negative effects 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.

Why you need to remove a bicycle fork

Obviously, there is no need to simply dismantle it from the bike. There are a number of reasons for this. replacement, overhaul and service. Replacement means removing an unusable part and installing a new one instead.

Repair. partial replacement of components. These can be bearings, washers, spring, damper or oil seal. Service includes adjustment, cleaning, lubrication.

The main symptoms that indicate removing the fork from the bike and putting it in order:

  • knocking on the move;
  • the fork is stuck and not adjustable;
  • bearing wear;
  • lack of lubrication (creaks);
  • cranking, heavy steering;
  • cracked legs and pants.

The device of the classic front shock absorption system is a metal spring and a rubber damper. Shrinkage of the spring and elongation of the elastomer rod degrade the properties of the shock absorber, making it stiffer. Regardless of the setting, the fork will knock on obstacles.

Backlash and tight handlebar travel indicate worn bearings and o-rings, as well as a dirty fork cavity. A suspicious creak when the bike is moving indicates that it is necessary to lubricate the part, and you cannot do without removing it.

Any mechanical damage leads to unexpected breakdown of the system. If cracks are found on the body and legs, the fork should be immediately replaced with a new one.!

In disassembling the shock absorber with your own hands, you will need tools:

  • Screwdriver Set;
  • flat sharp object;
  • sliding wrenches;
  • hexagon;
  • small hammer.

During operation, it will be necessary to clean and lubricate the part again, so you will need a can of grease, a few soft rags and gloves.

  • check the bike fork for integrity every 500. 1000 km;
  • clean the feet on the oil seals every 150. 200 km of the track;
  • apply a little grease to the stuffing box of the legs several times a season;
  • specially for hydraulic shock absorbers. change the oil every 5000 km.

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 on the sound: while he is deaf, we continue to press, sonorous. the ring is in place.

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

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 work in the reverse order.

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 the usual position. Now you need to pull out the steering wheel and remove the plug from the glass:

Unscrew the steering pin fasteners or anchor bolt completely.

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 carefully 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.

Dismantling the front fork for parts

To replace the part, you do not need to disassemble, but its repair will require you to get into the mechanism and carefully delve into it. Let’s consider how to sort out a spring-elastomer type suspension fork:

  • Unscrew the bottom fasteners with a hex wrench.
  • Remove the spring compression adjustment bolt. Preload. It is the main damper travel adjuster.
  • Remove the elastomer restrictor or damper.
  • Take off your pants.
  • Using a screwdriver, remove the seals from the pants.

The main reasons why the fork squeaks, makes knocks and does not smooth out vibrations while the bike is moving include wear of parts, water and dirt ingress, lack of internal lubrication. We put in order:

  • Remove all dirt from the inside of the pants.
  • Thoroughly wipe the fork legs, spring and seals.
  • Replace the defective part if necessary.
  • Install the elastomer damper (fill oil through the nipple for the hydraulic fork).
  • Lubricate the inner cavity. inject oil from a can.
  • Install Mounting Bolt and Preload.

How To Replace Your Mountain Bike Fork

It looks like a do-it-yourself bicycle fork bulkhead. Is it needed for a new part? There is an opinion that a plug that has been sorted out at once will be better tuned and will last longer. Much depends on the quality of the kit, but it will be found out in real riding conditions.

Scheduled repairs are done as needed, bulkhead once a season. And of course, you shouldn’t forget about prevention. After each ride, remove dirt from the surface of the oil seals, lubricate, check the fasteners and integrity.
