How To Lubricate A Bicycle Fork Without Disassembling

Bicycle fork: remove, disassemble, assemble, install

Bicycle fork device.

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 bike handling, and in addition, increases the 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. It will surely please the zealous owner of a two-wheeled friend, taking the high cost.

The plug without fail requires:

  • 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 plug, 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.

How often do you need to check

When properly selected, set up and maintained, a bicycle fork will significantly reduce the stresses that your hands and arms are subjected to while riding. In addition, if it is in good technical condition, it increases controllability and increases the life of the bearings (after all, in this case they suffer from vibrations much less). And the bike frame will last much longer

It is important to remember that without leaving the fork will quickly become unusable, and the price for a new one is quite high

Mandatory inspection of a bicycle fork includes the following:

  • Every 100-150 km. inspection, lubrication of the fork legs on the oil seals.
  • After 500-1000 km, you need to disassemble and lubricate the oil seals. It is imperative to inspect the “pants” of the fork for cracks and damage.
  • If your type of plug is oil, then every year you need an oil change (or after overcoming 4-5 thousand kilometers).

But before parsing the plug, you need to decide what type it is.

Dismantling the front fork for parts

It is not necessary to disassemble a part to replace it, but its repair will require “getting in” into the mechanism and thoroughly digging into it. Let’s consider how to sort out a spring-elastomer type suspension fork:

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

Admiring the disassembled suspension fork: on the left. legs, on the right. “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 elastomeric damper (fill oil through nipple for hydraulic yoke).
  • Lubricate the inner cavity. inject oil from the 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 fork that has been sorted out at once will be better tuned and 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 fasteners and integrity.

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 here will be considered such issues: how and how to lubricate the front fork, maintenance intervals 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 selected for disassembling the bicycle suspension fork. In this article we will analyze the RST GILA 100 mm spring-elastomer fork with a disc brake mount.

The bike 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 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.

Types of shock absorbers

More often than not, a suspension fork can only be found at the front of the bike, so manufacturers take care of reducing the force of impacts on the front wheel. Rear detail eliminates the drive wheel force that the front fork could not hide.

Shock absorbers are very different:

Spring-loaded ones, characterized by special rigidity. do not anticipate dampers.

With spring and elastomer. they consist of a metal spring and a rubber damper in the center of the fork. The forks are used in bicycles for traversing moderate to fine terrain. A significant disadvantage is the low resistance of the pin to cold temperatures.

Air. air is pumped into the plug, it just dampens the vibrations. However, over time, air penetrates through the smallest holes, how long such a shock absorber will last depends on the sealing characteristics of the cuffs.

Oil-filled. instead of a damper, the front and rear forks include an oil cartridge.

Why you need rear bike shocks

Cyclists are divided into two types: the hardtail and those who love comfort and safety. Lovers of a quiet ride must install a rear bicycle shock absorber. It is he who is considered the heart of the entire suspension of the bicycle, its correct selection and installation will significantly improve comfort and speed of movement on rough terrain.

How to assemble a bike fork?

Assembling the plug
runs 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.

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.

Difficulties in removing the front fork should not arise. 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 also need to be unscrewed in order to remove the plug. Everything is simple here.

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 C Volinets washer 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 connecting the fork to the handlebar. Next, this bolt is unscrewed (Do not be alarmed. it is quite long) from the tapered 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 bicycle wheel fender 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 fasteners to the wheel (here you need to loosen the nuts) and disassembly ends there.

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

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 enters. But using it for five seasons, no negative consequences were noticed. The advantage of this grease is 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 work 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 fill them in initially, which they DO NOT do.

We figured out how to lubricate the bike fork. Next, let’s see how to do this. We apply grease to the spring with an 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 of it in the trousers, 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 fork in 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.

Fork removal algorithm

To dismantle the front fork of an e-bike:

  • Unscrew all components attached to the fork: brake caliper, speed sensor, V-brake or disc brake hose, fender, etc.
  • Remove the bolts holding the stem to the rudder tube. Unscrew the anchor bolt.
  • Being careful NOT to touch the brake hose, remove and lower the stem.
  • Remove the spacer rings and the guide sleeve by carefully prying it in the cutting area with a compact screwdriver. Remove the rolling ring and bearing at the top.
  • Carefully remove the rudder tube from the glass. Remove bearing and rolling ring underneath. Remove the bicycle wheel by unscrewing the fasteners or loosening the eccentric.

How to disassemble a bicycle suspension fork

After we have removed the suspension fork from the bike, all of the above components, namely the bearings, cups and rolling rings, as well as the steering tube and second sections, should be removed from the old used grease. Applies a new one While it’s not worth it, we will add it back to the glass at the stage of installing the fork.

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

  • Turning the fork over and unscrewing the mounting bolts.
  • We remove the pants from the legs of the fork. If necessary, removing 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. Remember to remove dirt and grease from the cuffs of the bike fork, as well as from the inside of the pants themselves.
  • Then remove the lower travel stops and stop stops. To do this, I 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 the most self-made key for THESE cases. We attach the 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).
  • Remove old grease from all fork surfaces.

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

How to assemble and put the plug back

The assembly and installation process of the bicycle suspension fork is carried out in reverse order. The only thing that should be done carefully and carefully 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 it is imperative to eliminate them before the trip.

After you set everything up and start riding, the first time there will be an abundant release of lubricant through the cuffs of the bicycle forks. 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 remember to wash off excess lubricant after each ride.

How to lubricate a bicycle fork. conclusions

Maintenance of bicycle suspension forks is not an easy procedure and should be done by competent mechanics. Their help is especially relevant in situations where the suspension fork works with certain difficulties, and you need to find out the cause of the problem. But if you have free time, skills and tools, maintenance of the suspension fork can be done with your own hands at home.

In addition, you need to regularly carry out preventive measures. it is recommended to lubricate the fork legs with silicone grease before each rental. It does not harm rubber, and does not attract dust, does an excellent job with its tasks and does NOT cause difficulties when wiping off excess.

In our previous material, we present good advice for beginners and seasoned cyclists on how to ride an e-bike to get a new riding experience.

How to lubricate a bicycle chain

We proceed as follows:

  • By increasing the chain tension, move it to the corresponding large sprockets;
  • We thoroughly clean the chain from dirt, you can use a rag, press it against the free section of the bicycle chain and twist the pedal;
  • Then we lubricate the chain, it is better to apply 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 entire chain is lubricated, you need to intensively turn the pedals in the opposite direction for a minute. “idle” of the chain, and then, having selected the average speed, turn the bicycle chain in the forward direction.
  • At the final stage, 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. Therefore, do not 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:

  • She starts to sag;
  • Fuzzy gear shifting;
  • The extended chain will damage the cassette sprockets on the rear wheel.

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 lubricate the chain after 100 km of run, regardless of operating conditions. This is probably the most correct decision, since PLEASE READ to the regularity of maintenance.

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 here will be considered such issues: how and how to lubricate the front fork, maintenance intervals 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 selected for disassembling the bicycle suspension fork. In this article we will analyze the RST GILA 100 mm spring-elastomer fork with a disc brake mount.

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, you need to lubricate the “legs” of the plug after 150-200 kilometers, after 700 kilometers (on average) the oil seals are disassembled and lubricated, and annually or after a run of 3-4 thousand kilometers. Changing the oil in the shock absorbers completely.

Better show all fork care on. Than describe it in detail in text. For example, here you can see all the preventive maintenance operations for the front fork and shock absorbers:

Assembly and installation of the fork after lubrication

To assemble and put the plug back, you need to perform the above steps in reverse order:

  • Install 2 stems on legs and springs. Lock the adjustments on the fork legs.
  • Place the stops and stops located at the bottom on the rods.
  • Install the oil seals. Fix the pants on the fork legs. Tighten the bolts.
  • Put the assembled fork. Fix the stem and other dismantled elements.
  • If there are rudder tube play, eliminate them.

After inserting the lubricated fork back into the cuffs of her pants, lubricant will leak out, and this is normal. Gradually, excess lubricant will come out, and its release will stop. But for some time after lubrication, you will have to after each rental Wipe off the excess of the applied composition.

Why remove and disassemble the bike fork

The bike 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 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 trousers. If you have V-brakes installed, then dismantle them. This also applies to the speed sensor coming from the bike computer, front fender, etc.
  • We 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 brake hose or accidental impact of metal parts of the steering wheel in the frame DO NOT scratch the latter.
  • We remove the spacer rings and the guide sleeve (cone). To do this, gently 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 disassemble a bicycle suspension fork

After we have removed the suspension fork from the bike, all of the above components, namely the bearings, cups and rolling rings, as well as the steering tube and second sections, should be removed from the old used grease. Applies a new one While it’s not worth it, we will add it back to the glass at the stage of installing the fork.

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

  • Turning the fork over and unscrewing the mounting bolts.
  • We remove the pants from the legs of the fork. If necessary, removing 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. Remember to remove dirt and grease from the cuffs of the bike fork, as well as from the inside of the pants themselves.
  • Then remove the lower travel stops and stop stops. To do this, I 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 the most self-made key for THESE cases. We attach the 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).
  • Remove old grease from all fork surfaces.

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

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

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 your routes contain an abundance of dust, mud, sand and other abrasive material, 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.

Conclusion

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.
