How to lubricate an e-bike plug without disassembling?
For proper lubrication, the fork must be disassembled. Without disassembly, it can only be cleaned using silicone grease or industrial oil. It is enough to drip a little oil at the place where the legs of the fork enter the pants, press down on the steering wheel and perform up and down movements so that the oil penetrates deeper. After that, it remains to wipe off the excess oil and return the protective anthers to their place. After this operation, the legs of the fork remain practically dry, with a thin layer of grease. Dirt sticks to oil weakly and can be cleaned off with anthers without any problems.
How and how to properly lubricate the front fork of a bicycle?
There are various options for how to lubricate a bicycle spring fork. Litol grease is well suited for these purposes. 24. It is designed for use in a wide temperature range (from 50 to 150 ° C), does not thicken and confidently copes with its tasks. It is undesirable to pour liquid oils into the fork pants in order to avoid them dripping, the mechanism running dry, the jerky functioning of the spring and other problems in the operation of the shock absorber.
In general, the choice of bicycle lubricants is very wide, but they can all be divided into 3 groups:
- Thick (consistent). Reliable and durable formulations that work well over a wide temperature range. But they are not easy to apply and attract dust. The thick formulations are ideal for machining bearings, arm bushings and other slow rotating components. Popular greases. petroleum jelly, lithium, graphite and calcium formulations.
- Liquid. Easy-to-apply products, easily poured even into unassembled units. Surplus of such funds can be easily wiped off. But liquid lubricants change viscosity when the temperature changes and easily drain from surfaces. Bicycle forks are lubricated with industrial oil.
- Two-component. These products are composed of a thick oil and a solvent. They are convenient when processing prefabricated mechanisms. Popular types of 2-component lubricants are silicone, teflon and wax. The latter requires more frequent updates.
Now let’s look at how to lubricate an e-bike plug by disassembling it. It is necessary to apply generous grease to the spring, ramming the composition between its rings. Excess grease will flow out through the stem bore and packing box. Additionally, you need to apply a lubricant to the grooves of the cuffs and pants. All rubbing elements must be lubricated with a thin layer. At the end of the lubrication process, it remains to assemble and install the fork back.
How and how to lubricate a bicycle fork?
The bicycle fork performs shock-absorbing functions, smooths out shocks, reduces the load on the cyclist’s arms, and reduces wear on the frame and other elements of the bike. Periodically, she needs to carry out repair and preventive measures: applying new grease, replacing bearings, oil seals or other worn out elements, aligning the steering tube and performing similar work. Before lubricating a suspension fork on a bicycle or replacing worn components, it must first be dismantled and disassembled.
It is recommended to lubricate the oil seals after about 700 km of run, at least once a season, and to sort out and lubricate the entire fork with a lubricant at a frequency of 4000 km. If the vehicle is operated in conditions of increased exposure to sand and other abrasive materials, its fork will have to be lubricated more often. They say about the need for prevention or repair of the fork: squeaks, knocking and other suspicious sounds during driving, jamming, uncontrollability, backlash, cranking or difficult movement of the steering wheel, cracks in pants or legs and other similar defects.
Fork disassembly algorithm
Before you lubricate the bike fork, you need to carefully remove the used grease from the elements and disassemble. New grease will be applied later, before reassembling the fork into the glass. To disassemble the plug, you should:
- Turn the fork over, remove the bolts.
- Remove the pants from the fork legs. Remove the oil seals as needed.
- Clean up past grease and dirt everywhere, including cuffs and inner edges of pants.
- Remove the lower stops and stops from the rods without undue effort.
- Using a special wrench or an alternative device, unscrew the adjustments on the fork legs. Remove the springs with caps and elastomers and 2 stems on legs.
- Completely remove any residual grease from the fork components.
After these procedures, the bike fork is ready to apply new grease.
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 legs of the fork. Tighten the bolts.
- Put on the assembled fork. Fix the stem and other dismantled elements.
- If there are rudder tube backlashes, 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 wipe off the excess of the applied composition after each rental.
Algorithm for removing the plug
To remove 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.
- Taking care not to hit 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 top rolling ring and bearing.
- 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.
Maintenance of a bicycle suspension fork is not an easy procedure and should be left to a competent mechanic. 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, does not attract dust, does an excellent job with its tasks and does not cause difficulties when wiping off excess.

How to lubricate the front fork of a bicycle? General issues
Nevertheless, with all the variety of bicycle suspension forks, there are a number of principles and points common to all of them that relate to their maintenance, including lubrication.
How to lubricate a bicycle fork?
In technology in general, and in bicycle technology in particular, only mutually moving parts, more precisely, their rubbing pairs, are subject to lubrication. For this reason, owners of bicycles with rigid rigid forks can safely ignore this information, since they have no moving and rubbing elements by default. It may be relevant only for owners of soft shock-absorbed bicycle suspensions of the front (and also rear) wheels, who have certain ambiguities regarding the organization of lubrication of shock absorbers.
So, the happy owner of a bike with a soft amovilka felt something wrong in its work, or simply decided to lubricate it in advance as a preventive measure. If he is still an inexperienced bicycle kettle, then two key questions arise in front of him in full growth:
- how to lubricate a bicycle fork?
- how to lubricate the bike fork?
Unfortunately, these key questions cannot be answered straight away. Why? Because there are many varieties of bicycle shock absorber designs, plus their numerous structural nuances are added by almost each of their manufacturers. And each of these designs has its own characteristics in terms of the order and technique of lubrication of the bicycle suspension fork.
How to lubricate a bicycle fork?
Shock absorbers for wheeled vehicles, including bicycles, are mechanisms made with sufficiently high accuracy tolerances. So the question is how to lubricate the fork of a bicycle? requires the most careful attention and understanding of technical nuances.
Strictly in relation to amovilka spring-elastomer design (lubricated), you should use only special bicycle lubricants of two-component composition: Teflon or silicone. They are film-forming teflons and silicones diluted with an organic solvent (Teflon) or a diluent (dispersion silicone), which, by their state of aggregation, are conditionally solid amorphous substances. Their characteristic feature is that after application they form a non-adhesive (non-sticky) film with a low coefficient of friction, on which road dust suspended in the air is deposited much worse than on a fatty organic lubricant.
Yes, indeed, the price of special teflon and silicone greases bites. Therefore, many cyclists are tempted to lubricate their front suspension forks with all-purpose, one-piece lubricants, which are more affordable. Most often, liquid oils (industrial, any motor), or solid lubricants (Litol-24, graphite) are used for this purpose.
But, nevertheless, this should not be done, because a thin greasy (sticky) film of such oils and greases during the operation of the shock absorber is inevitably carried out on the surface of the rods of the inner pipes outside the sealing gland, and then it is also brought into the glass along with the adhered to her with road dust. Very soon, an abrasive dust-oil mixture forms inside such a shock absorber, which quickly eats up precisely fitted rubbing pairs of its mechanism, and incapacitates it.
Any bicycle assembly tends to wear out during the operation of the bicycle. In order to extend the life of a certain element of the bicycle, it is necessary to change the lubricant in a timely manner. Bicycle lubricants are used in parts such as: bicycle fork, steering column, pedals, bicycle chain (pins), bottom bracket, bushings, shift cables / brakes.
Depending on the unit in which it will be used, lubricants are liquid and plastic (consistent). Liquid lubricant is placed in a plastic bottle with a thin nose, plastic. in a tube. Consistent paste is more durable, it can withstand low and high temperatures, but due to its composition, it is difficult to apply to the unit and collects a lot of dust and dirt. Liquid is conveniently applied to the knot, but due to the composition it tends to drain, thereby there is a chance to smear clothes or hands, changes property when the temperature changes.

Greases are used for lubricating bearings, threads, bushings and levers. Lithium greases are used to increase the sliding effect of parts and expand the used temperature range (from 50 to 180). The disadvantage is poor interaction with aluminum material. Calcium. used in units where moisture can get in, for example, a brake lever, bearings in the hub of a bicycle wheel. Calcium grease is used to protect the bicycle from corrosion; among the shortcomings, one can single out a narrow temperature range in which it can be used (from 30 to 50). Graphite grease is a powder that effectively increases the slip coefficient.
A thinner but viscous grease is used to lubricate rotary brake levers, shift cables or brakes, ratchets, bicycle hubs, most importantly, apply in small quantities in order to prevent the release of excess oil. Alternatively, grease can be used in these assemblies. Liquid lubricant is recommended to renew one. twice a month, as well as after each exposure to severe rain.
It is also worth considering a separate type of lubricant. two-component lubricant. Supplied in cans and vials. Composition. thick oil and solvent. It is used to lubricate bicycle chains, bushings, chain tensioners.
Teflon Lubricant. Recommended for bike chain lubrication due to its high evaporation resistance.
