SHOCK ABSORBER ASSEMBLY

DISASSEMBLY AND ASSEMBLY

Disassembly Steps 1-13 & Required Special Tools:

DISASSEMBLY SERVICE POINT
[[A]] COIL SPRING NUT (SELF-LOCKING NUT) REMOVAL

CAUTION:
^ To hold the coil spring securely, install special tools MB991237 and MB991239 evenly, and so that the space between both arms of the special tool will be maximum within the installation range.
^ Do not use an impact wrench to tighten the bolt of special tool MB991237. The usage of impact wrench will break the special tool.





1. Use special tools MB991237 and MB991239 to compress the coil spring.

WARNING: Do not use an impact wrench to remove the coil spring nut (self-locking nut).
^ Vibration of the impact wrench will cause special tools MB991237 and MB991239 to slip and cause personal injury.
^ Vibration of the impact wrench will cause the valve inside the shock absorber to drop out.





Use a hexagon wrench and a pipe to secure the piston rod, and then remove the coil spring nut (self-locking nut) using special tool MB991681.

ASSEMBLY SERVICE POINTS
]]A[[ COIL SPRING INSTALLATION

CAUTION: Do not use an impact wrench to tighten the bolt of special tool MB991237. It will break the special tool.





1. Use special tools MB991237 and MB991239 to compress the coil spring, and install it to the spring seat of the shock absorber.
2. Align the end of the coil spring with the stepped section of the spring seat of the shock absorber.

]]B[[ SHOCK ABSORBER INSULATOR INSTALLATION








Install the shock absorber insulator as follows.
1. Position the coil spring lower end as shown.
2. Position a center line (A) of the shock absorber lower bushing inner pipe as shown from the arrow (B) on the shock absorber insulator.

]]C[[ COIL SPRING NUT (SELF-LOCKING NUT) INSTALLATION
1. Temporarily tighten the coil spring nut (self-locking nut).

CAUTION: Do not use an impact wrench to tighten the bolt of special tool MB991237. It will break the special tool. Vibration of the impact wrench will cause the valve inside the shock absorber to drop out.





2. Remove special tools MB991237 and MB991239. Using special tool MB991681, a hexagon wrench and a pipe, tighten the coil spring nut (self-locking nut) to 23 ± 2 Nm (17 ± 1 ft. lbs.).

SHOCK ABSORBER DISPOSAL

WARNING: Wear goggles when drilling to protect your eyes from flying metal debris.





The gas must be discharged from the shock absorber before discarding it. Place the shock absorber horizontally with its piston rod extended. Then drill a hole of approximately 3 mm (0.12 inch) in diameter at the location shown in the illustration and discharge the gas.

INSPECTION
^ Check the rubber parts for damage or deterioration.
^ Check the coil spring for deformation, deterioration or damage.
^ Check the shock absorber for deformation.
