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. Remove auxiliary drive belt.





2. Loosen 3 clips securing air intake hose. Release air intake hose and position aside.
3. Position container to catch spillage.
4. Release clip on pump suction hose and disconnect hose.

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

2. Position pulley to ACE pump and fit bolts. Restrain pulley and tighten bolts to 25 Nm (18 ft. lbs.).
3. Clean mating faces of ACE pump and mounting.
4. Connect suction hose to ACE pump and secure with clip.
5. Ensure there is sufficient fluid in ACE/PAS reservoir to prime ACE pump.
6. Position ACE pump below level of ACE/PAS reservoir, with suction hose uppermost, and allow fluid from ACE/PAS reservoir to completely fill ACE pump.
7. Position ACE pump to mounting, fit bolts and tighten to 25 Nm (18 ft. lbs.).
8. Rotate ACE pump clockwise (viewed from pulley end) until a steady flow of fluid runs from outlet port.
9. Connect pressure pipe to ACE pump with banjo bolt and new sealing washers. Tighten banjo bolt to 28 Nm (21 ft. lbs.).
10. Position air intake hose and secure clips.
