Nowadays, when people talk about MTB, it is very common to have shock absorbers, and casing type forks are the more common form of shock absorbers. If it is not properly maintained, it will reach the end of its service life in advance and become more and more hardened, and gradually lose its necessary comfort.
Necessary tools for maintenance
- Hexagonal wrench
- Wooden mallet
- Oiler
- Pump
Steps.
1 Clean the dirt inside the rubber sheath
The rubber sheath is a fairly effective layer of protection on top of the shock column, however, in each cleaning is to fold it up, and then use a rag to polish the fork telescopic column, and regularly check the shock column for damage.
2 Apply oil to the telescopic column
After each maintenance, put a few drops of oil or a thin layer of grease on the telescopic column to ensure that the column stays in excellent condition for a long time.
3 Disassemble the shock absorber
All shock forks have fixing screws, some on the outside, some on the inside, as for air pressure shock forks, the air must be removed before disassembly.
4 Clean the inside of the shock
Wipe off all the dirt accumulated inside the shock with a rag. Remember, do not use any solvent, otherwise it will cause damage to the inside of the shock, and check if there is any damage inside.
5 Oiling
Apply a thin layer of grease inside the shock post. A good oil for the fork should have the characteristic of not eroding the Teflon coating on the inner wall.
6 Put back the shock absorber
When assembling, do not tighten the screws too much, wipe off the extra grease and put the dust cover back in place.
7 Adjust the air pressure of the shock fork
Some shock forks, at least 3 to 4 times a year for pressure check, never use the air compressor to flush the air! A fork internal capacity is limited, when the air compressor will cause the internal components to be scrapped.
