(1) DAMPER ROD (2) MARK
(3) HYDRAULIC PRESS
Damper
Check for oil leakage from the damper rod.
Replace the damper assembly if the oil is leaking.
Mark the damper rod at the first 10 mm (0.4 in)
exposed from the damper body.
Place the damper rod on a scale and measure the
force required to compress the damper until the
10mm (0.4 in) mark is flush with the damper body.
Compression force: 150 - 195 N (15.4 - 20.0 kg)
If the force required is less than 150 N (15.4 kg),
nitrogen is leaking.
Fill the reservoir with 980 - 1,280 kPa (10.0 - 13.0
