Filter - high pressure - ACE

$% 60.60.21

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.

l

ACE components are thoroughly cleaned
externally before work commences;

l

all opened pipe and module ports are
capped immediately;

l

all fluid is stored in and administered
through clean containers.

Remove

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

3. Remove filter cap and discard 'O' ring.
4. Fit M6 bolt into base of filter and pull on bolt to

remove filter from valve block. Do not turn
filter in valve block.

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

Refit

1. Ensure new filter has 'O' ring fitted, then fit filter

to valve block.

2. Fit new 'O' ring to filter cap. Fit cap and tighten

to 35 Nm (26 lbf.ft).

3. Lower vehicle.
4. Check fluid level in ACE/PAS reservoir.
