What is a bicycle maintenance course? I will not touch on complex things – for example, the carriage unit, which must be disassembled with a special tool in order to get to the bearings. With such questions, you can get help from service centers, and I often use their services when I need to make a serious replacement or adjustment. I will talk about places that are very easy to get to and make their planned preparations for the operation process.
Lubrication system diagram
Before proceeding with the lubrication components parts, I perform small cleansing procedures with a damp cloth and then wipe dry. This is followed by an external inspection and inspection of all fixing bolts and nuts, for their reliable tightening. The main thing here is not to overdo it – some bolts are screwed into aluminum threads and even a child will have enough strength to break it.
So, all the parts and assemblies are normal, the wheels are not loose and pumped up, the steering wheel does not play, the spokes are not weakened, etc. Let’s start! For lubrication, depending on what needs to be processed, I use two types of oils.
Types of lubrication system
The first type is any universal plastic lubricant for mechanisms, in a convenient tube similar to toothpaste. Usually lithium-
The second is liquid engine oil, a plastic bottle with a thin spout-nipple. You can use a spray lubricant, but I did not have it at hand, so another time-
How to service suspension forks?
In the place where her legs (shiny pipes) enter her pants (the lower part with jumper), drop a small amount and, leaning on the steering wheel with your whole body, swing up and down so that it penetrates deeper. Wipe off any excess with a cloth and replace the protective anthers. In the end, the legs should be practically dry – the purpose of the work is to clean, not grease (for full lubrication, you need to disassemble the plug). After this operation, a thin layer of grease will remain on your feet, the dirt sticks poorly to it and will be easily peeled off with anthers.
Brake cable lubrication – Gear shifting cable
This operation should begin to do only when the cable has already begun to stick! Good stainless cable and braid (shirt) do not need to lubricate, it leads to the accumulation of dust on them and accelerated re-pollution. If you start to lubricate them – be prepared to do it regularly in the future.
No need to climb into those areas where the cables are connected to the switches, start lubricating with the frame. They are usually clamped in the mounting grooves and easy to remove. Especially carefully should clean the cable and the casing near the rear switch, this is the dirtiest place.
As a result, in front of you will be most of the cable, which you first need to clean, and then miss the mark and put everything back. A few clicks of the brake levers or levers arms – and you can move on to the next table.
Steering column grease
In narrow connections, which can be reached with a medical syringe with a needle, squeeze out some oil and twist the steering column in different directions.
First, you need to bicycle maintenance course and clean the stars in front and behind, as well as the rollers of the rear switch. If the chain is dirty, it should be washed with a solvent and wiped dry with a clean cloth. Then drip each roller out of the oil can with liquid oil, turn the pedals back until the oil spreads all over the chain, and again wipe off excess lubricant from the chain, rollers, and stars with a clean rag.
Parts requiring maintenance with plastic (solid) grease Front and rear wheel lubrication-
If you have flat wrenches to adjust the cones, you can disassemble the bushes and grease them with grease from the inside. If there are no such keys, then it is better not to touch them at all, but simply clean lubrication components them of dirt and dust as much as possible. Rear (and front) stars cannot be lubricated, they should always be dry and clean. They can be easily cleaned with a stiff metal brush.
Best grease for bike bearings
Armed with a thin flat screwdriver or knife, pick up the plastic plug from the end of the pedal. Sometimes, on more expensive pedals, it can be unscrewed with a hexagon. After that, it will be possible to adjust the pedal bearings and tightly fill them with grease. You cannot regret the grease; the surplus will come out later. After all these manipulations, return everything to its place and spin the pedals so that the lubricant penetrates into the required areas.
Bicycle seat shock absorber
Under the saddle on my stock is an additional shock absorber, which dampens the vibration created during driving. Lift the protective rubber cover, push the grease inside and put the rubber band back in place. Sit on the bike and swing slightly up and down.
So, everything seems to be done at home, you have done. Now you can go out and spend walking “races.” If, after the procedures performed, in the process of riding, extraneous metallic sounds or mechanical squeaks are heard, then you should conduct a professional inspection of the bicycle and entrust this business to the service center.
If you want the chain to stay clean for a long time and do not require frequent lubrication and washing, then boil it in paraffin (after washing it clean, this is very important). It will better resist dust, dirt, and water, and the bicycle maintenance course is chain cleaning process will subsequently be simplified.
Conclusion of an essay
Some types of oil and grease are not allowed on some parts of the bike, as this can lead to accidents. This applies to the wheel rim. Do not allow oil to get into the area over which friction of the brake pads occurs, otherwise, the brakes will stop working completely. The same applies to brake pads and discs. If the oil is still contaminated, then rinse and decrease the contaminated areas with alcohol or acetone (by no means with gasoline, etc.), wipe these places dry with a rag and check the operation of the brake system for operability.
