Pipe Assembly - Valve Block To Rear Actuator - ACE

Service Repair No - 60.60.33

CAUTION: The ACE hydraulic system is extremely sensitive to the ingress of dirt or debris. The smallest amount could render the system unserviceable. It is imperative that the following precautions are taken:
^ ACE components are thoroughly cleaned externally before work commences.
^ All opened pipe and module ports are capped immediately.
^ All fluid is stored in and administered through clean containers.

Remove

1. Raise vehicle on a ramp.
2. Position container under valve block to collect fluid spillage.





3. Remove 2 bolts securing 2 rear pipe clips to chassis.
4. Remove 2 nuts securing rear anti-roll bar links to axle.
5. Release links from axle and pull long arm down for access to actuator pipe unions.
6. Position container under actuator to collect fluid spillage.





7. Remove 2 cap nuts securing pipes to ACE rear actuator. Disconnect pipes, remove and discard sealing washers.





8. Remove 2 nuts securing rear pipe clamping plate. Release clamping plate and pipes from valve block.

CAUTION: Always fit plugs to open connections to prevent contamination.

9. Remove pipe assembly.
10. Remove collets and clamping plate from rear pipes.

Refit

1. Ensure valve block and pipe connections are clean.
2. Install clamping plate and collets on rear pipes.
3. Position pipe assembly to vehicle and connect pipes and clamping plate to valve block. To avoid damage to seals, keep pipes square to valve block. Fit and tighten nuts securing clamping plate to valve block to 21 Nm (15 ft. lbs.).

CAUTION: Ensure pipes are installed in their correct ports or serious system damage will occur.

4. Fit bolts securing rear pipe clips to chassis and tighten to 6 Nm (4.4 ft. lbs.).
5. Connect pipes to actuator with cap nuts and new sealing washers. Tighten cap nuts to 29 Nm (21 ft. lbs.). Ensure pipes are not under tension or kinked.
6. Ensure washer is in place on lower ball joint of each anti-roll bar link, then connect lower ball joints to axle and tighten nuts to 100 Nm (74 ft. lbs.).
7. Renew ACE high pressure filter.
8. Bleed ACE hydraulic system.
9. Lower vehicle.
