How to remove the front fork on a stealth bike

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 go;
  • 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 “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).

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 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.

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 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.

Dismantling the front fork for parts

You don’t need to disassemble a part to replace it, but its repair will require you to “fit” into the mechanism and dig into it thoroughly. 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 the “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.

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.

Front forks

The assortment of forks is diverse, they are grouped according to the type of shock absorption and device features.

  • tough;
  • spring;
  • spring oil;
  • air;
  • air-oil;
  • spring-elastomeric.

Hard ones contribute to the development of maximum speed on a flat asphalt road. Air, spring / elastomer, and spring forks soften sidewalk descent, but do not completely eliminate shock from small cobblestones. Air- and spring-oil assemblies remove even minor shocks as a result of a collision with a gap in the asphalt surface.

Air and air-oil forks can be adjusted for athletes whose weight differs from the usual 70-100 kg. To adjust the stiffness of these elements, you will need a high pressure pump, you will need to carry it with you on long journeys.

According to the features of the device, bicycle forks are divided into:

How to Remove and Reinstall a Front Fork on a Bicycle

  • ordinary, or one-sided;
  • one-legged;
  • double-crown;
  • inverted type.

Conventional (one-sided) mechanisms are used on vehicles that are intended for cycling tourism, riding on uneven terrain. Double corners are required for high-speed exits outside prepared tracks. Inverted structures are needed for jumping from dumps. One-legged elements support the axle with a cantilever attachment on one side only. This allows the camera to be repaired without first removing the front wheel.

Maintenance, its and frequency

A routine inspection helps prevent serious problems from occurring, but it is not enough to keep your bike performing well. It also requires constant care, which consists in:

  • cleaning and lubricating the feet in the oil seals (every 100–150 km);
  • disassembly and full lubrication of oil seals (after passing 500-1000 km);
  • oil change in oil forks (at least once a year).

It is recommended to lubricate the bicycle fork at least once a season, but if the vehicle is used intensively, this should be done more often.

  • Pour oil under the boot. use a syringe for this procedure.
  • Design a fork to spread the oil evenly.
  • Wipe off excess grease.

In addition to lubrication, maintenance also includes maintaining cleanliness. To prevent dust from entering the oil after the next trip, the legs of the fork in the area of ​​\ u200b \ u200bthe anthers should be carefully wiped with a soft cloth.

Fork repair and disassembly process

Manipulations to completely change oil, seals or oil seals and 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 a spring-elastomeric 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 that coordinates the spring force, 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. Replacing a shock absorbed bicycle fork should be entrusted to a person who specializes in such work, or 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.

How to assemble a bike fork?

The fork assembly 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 remove and disassemble the front bike fork

Many modern bicycles are equipped with a shock absorption system that improves handling and comfort while riding this vehicle. As a rule, bicycles are equipped with a front suspension fork, the presence of which makes it possible to easily overcome various irregularities on the road at a sufficiently high speed. The load on the hands and palms is at the same time very small. By helping to reduce vibration, a well-tuned fork extends the life of other components as well. The period of use of the fork itself will prolong proper care and constant maintenance.

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 we 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.

How To Replace Your Mountain Bike Fork

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.

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, 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 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, for the first time, there will be an abundant release of lubricant through the cuffs of the bicycle 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.

Fork routine inspection

Often, it is the prophylactic inspection of the fork that makes it possible to timely identify minor deviations from the norm in the operation of the device, and, accordingly, prevent a more serious breakdown. Typically, a visual inspection of the fork includes checking:

  • dropout states;
  • fork legs for dents, scuffs and other marks;
  • oil seals (anthers) for mechanical damage and oil leaks from under them;
  • pressure in air chambers;
  • the presence and condition of the lateral play of the legs in the “pants”;
  • the condition of the fastening bolts under the “pants” of the fork and adjustment knobs.

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.

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.

Fork maintenance intervals

The frequency of changing the lubricant of the 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.

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.

  • 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.
