How to clean your bike s flywheel, rear transmission, guide wheel and chainring

It depends on how long your car has been used and how dirty it is.

If you and your friend on the first floor said that you don't want to take it down and clean it, it will definitely not be clean.

I really don't want to decompose, but I can actually clean it. There are professional cleaning liquids, which are more expensive. It can also be cleaned with diesel.

Slowly turn the pedal with one hand to turn the flywheel upside down, and use a small brush with diesel fuel to clean it. If you can't get it in the flywheel, you can use a rag to cover the ice cream stick and wash it with diesel.

In the end, I still don't recommend the above methods, or disassemble and clean it is not good, upstairs is very good.

Do it yourself, and you'll have a sense of pride in riding your bike.

Find two oil brushes, one large and one small, find a container, pour some diesel or gasoline, and then put the parts to be cleaned inside, cover the container in an object, after about 40 minutes, take out the cleaning so that the wash is relatively clean, after the oil brush is brushed, it will be good to dry for a while, if you don't want to dismantle the car, prepare a long tweezers, roll a cotton cloth dipped in gasoline to clean the gaps.

There is also a simple way, which is to buy a kind of cleaning liquid with a nozzle for cleaning the range hood, a dozen or so, spray it, dry it with a cloth, and then apply chain oil after drying.

First decompose, then prepare: kerosene, toothbrush, cotton cloth.

Just brush the soles of your shoes, soak them well, brush them back and forth, and finally wipe them off and then oil them, and then assemble them back.

1. Wipe the rear derailleur guide wheel, turn the crank with one hand, hold the rag with the other hand, squeeze the teeth of the guide wheel with your index finger and thumb, and wipe these teeth clean.

2. Clean the flywheel, put the rag between the two tooth pieces, and drag the rag back and forth to wipe the tooth pieces until each tooth missing piece is wiped clean.

3. Wipe the derailleur, flywheel and crankset, and the mud on the derailleur, flywheel and crankset can be cleaned with a short-bristled brush dipped in dish soap. The brushes of the derailleur and flywheel will be stained with oil, so you can't use the same brush to clean the frame and the drivetrain, otherwise the oil-stained brush will stain the bike. Remember to dry it with a pin-only cloth after brushing.

To clean the flywheel, you need to apply a degreaser that does not harm the paint to the flywheel, and then rinse it with clean water.

Note: After rinsing with clean water, the flywheel needs to be wiped dry with a dry cloth.

The mountain bike can only be washed by itself, and many dead corners can not be washed, so you can only take the car shop to disassemble the whole vehicle into parts for detailed cleaning and maintenance by professional technicians.

Wash your own car and get together:

Buy a set of bicycle cleaning brushes (if you don't want to buy, small toothbrushes, large washing brushes are necessary, and you can't only use them to wash cars in the future) Find a suitable location, there is a dam or a large toilet. It is best to have a faucet to pour water, and if you don't have it, wash it in a basin.

Remember that the brakes must not be stained with oil, including the caliper and disc. Therefore, when flushing, you should not flush from the chain side to the disc brake side. Clean the body with a special bicycle cleaner (if not, use dish soap water), especially the chain, flywheel, and crankset, carefully brush it clean, brush off everything that can be brushed, and prepare a slender iron wire or long bamboo skewer to poke off the stubborn oil stains.

Rinse with the most clean water, lift the car and go down to the ground freely, and shake off most of the water. It's best to go out for a lap and get the water out of the bike. After the whole vehicle is dry, oil the chain.

Precautions: In order to ensure the braking effect, wipe the net disc with alcohol. Never use a high-pressure water gun to flush the car, and use an ordinary faucet to be careful not to flush too much water to the front, middle and rear axles.

When the bike is covered in mud and the wire pipe is contaminated and unusable, it is time to give the bike a full body bath. It should be noted that there are many bearing parts in the bicycle, and these parts are very taboo to the invasion of water, so when cleaning, do not use high-pressure water flow, and be especially careful where there are bearings.

Introduce the steps and process of replacing a mountain bike flywheel.

Generally, use a cloth to pull vertically to wipe off the oil sludge on the side of the flywheel, use a toothbrush to remove the oil sludge before the teeth, and then reapply the chain oil! If it's too dirty, you have to go to the car shop and remove it with a special tool, soak it in kerosene first, then use a brush to remove the sludge on it, and reassemble it!

Spray with WD-40 (be careful not to spray on the disc brake disc), take a brush to brush, and then apply some chain oil from the roof stone, after 15 minutes, take a dry rag to wipe off the excess oil.

A high-pressure water gun, of course! 3 yuan a time, clean and clean, there is a car wash. I basically go once a month.

It can be cleaned with gasoline or carburetor cleaner, kerosene, diesel, etc.

There is a dedicated ultrasonic cell for cleaning.

2. Insert the special disassembly tool of the rotary tower wheel into the tower wheel and rotate it counterclockwise with a large live wrench to remove the tower wheel.

3. Screw the new tower wheel clockwise into the thread of the hub, and tighten the tower wheel with the rotary tower wheel removal tool.

4. Assemble the wheels back into the frame and lock them tightly.

Second, the replacement method of the cassette tower wheel:

1. Open the quick release or lock nut of the rear wheel and remove the rear wheel group.

2. Insert the special disassembly tool of the cassette tower wheel into the locking cover of the tower wheel.

3. Clamp the special tool for fixing the cassette tower wheel on the outside of the tower wheel.

4. Hold the tower wheel disassembly tool in the left hand, hold the tower wheel fixing tool in the right hand, and at the same time force into the arms to remove the locking cover.

5. Take out the tower wheel by removing the locking cover, and then put the new tower wheel into the tower base and screw it into the locking cover.
