Clean and Inspect
1 Clean all components in a commercially available cleaning fluid and blow dry using compressed air.
2 Inspect the springs and ensure they are not distorted or broken, replace as required.
3 Inspect all machined surfaces for damage, wear or burrs.
Reinstall
Reinstallation of the 1 – 2 accumulator assembly is the reverse of the removal procedure, noting the following:
1 Lubricate a new seal with petroleum jelly and install it to the piston. Ensure the piston seal does not bind in the piston groove.
2 Tighten the three bolts attaching the accumulator cover to the correct torque specification.

To prevent personal injury, wear safety
glasses when removing the clip.
NOTE
Note the following when removing the solenoid:
• If required, rotate the solenoid until the flat
part of the clip becomes visible.
• The removal is only necessary to access the
TCC solenoid attaching bolts.
4 Using a hooked piece of wire or a small flat blade screwdriver, remove the clip (1) retaining the
TCC PWM solenoid (2).
5 With a twisting and pulling motion remove the TCC PWM solenoid from the control valve body,
remove and discard the O-ring.
