For many motorcycle owners, changing the fork oil is one of the things they never experience. Neglecting this service can result in reduced ride quality, premature fork wear, and abraded fork seals that allow oil to enter the front brakes.
Functions of a lubricant. What is it used for?
Fork oil is used in the shock absorber system, provides working out shocks and bumpiness of the surface being driven by transport. The viscous lubricant reduces the wear of mechanisms, reduces the friction force between parts at the time of use.
The consistency and composition of modern oils covers the rubbing particles of structures with a thin film. It protects against premature destruction of metals, the occurrence of rusty deposits.
Marking and characteristics. Packaging Information
Viscosity is the resistance of a fluid. Measured by flowing a specified amount of liquid through a capillary tube (called a viscometer). The flow rate is expressed in square centimeters per second or centistokes (cSt).
The following combinations are indicated on oil containersnumbers and Latin letters: 0W, 2, 5W, 5W, 7, 5W, 10W. These designations are not enough to make a purchase. Before going to the store, it is advisable to familiarize yourself with the characteristics of the goods sold on the manufacturer's website.
Pay attention to the following parameters:
- Viscosity Index (VI);
- boiling point Boiling Point, °C;
- Pour Point, °C.
Often, the manufacturer indicates the kinematic viscosity at different temperatures. Such information will help experienced mechanics to understand the advantages and disadvantages of a particular company.
How often do motorcycle fork oil change? Tips from experienced bikers
Lubricant loses lubricity, gets dirty, and it is advisable to change it every 10,000 miles or once a year. You can quickly change the fork oil in the following way:
- Remove the front wheel.
- Remove the plug cap and stopper.
- Measure the height of the fork legs.
- Remove fork legs.
- Unscrew the shock absorber bolt, clean.
- Install the shock rod.
- Pour in new oil.
- Reinstall fork legs.
- Carefully insert the springs, spacers and washers, then the fork caps.
Before starting work, check the manufacturer's manual to determine what type and viscosity of oil is recommended. Lubrication has a unique set of requirements, and machine lubricant counterparts have never beenshould be replaced with fork oil.
