2. Inspect for damage and oil leakage.
3. Inspect the rubber bushing for deterioration and wear.
4. Compress and extend the shock piston at least three times. Verify that the operational force does not change

and that there is no unusual noise.

FRONT SHOCK ABSORBER DISPOSAL

id021300800900

Warning

• Whenever drilling into a shock absorber, wear protective eye wear. The gas in the shock absorber

is pressurized, and could spray metal chips into the eyes and face when drilling.

1. Clamp a shock absorber on a flat surface or with the piston pointing downwards.
2. Drill a 2— 3 mm {0.08— 0.12 in} hole at a point

20— 30 mm {0.8— 1.2 in} from the bottom of the
tube, so that the gas can escape.

3. Turn the hole downwards.
4. The oil can be collected by moving the piston rod

several times up and down and cutting the tube at
the end.

5. Dispose of waste oil according to the waste

disposal law.

Note

• Shock absorber gas is nitrogen gas.

• Shock absorber oil is mineral oil.
