engine models
Removal
1 Disconnect the battery negative lead.
2 Drain the fluid from the hydraulic system as
follows.
a) Remove the cap from the fluid reservoir.
b) Place a container under the high pressure
fluid pipe union on the steering gear, then
unscrew the union.
c) Allow the fluid to drain into the container.
d) Turn the steering from lock-to-lock
several times to completely drain the
system.
3 Counterhold the pump spindle, and slacken
the pump pulley securing bolts (see
illustration).
4 Remove the pump drivebelt as described in
Chapter 1.
5 Remove the bolt securing the alternator to
the adjuster bracket, then swing the alternator
upwards, clear of the power steering pump.
6 Remove the securing bolts, and withdraw
the pump pulley.
7 Unscrew the fluid pipe union, and
disconnect the pipe from the pump.
8 Slacken the hose clip, and disconnect the
fluid hose from the pump. If the hose clip is of
the crimped type, discard it and fit a new
worm-drive clip on refitting.
9 Unscrew the two front and two rear
securing bolts, and withdraw the pump from
the mounting brackets (see illustrations).
10 The pump cannot be overhauled, and if
faulty must be renewed.
Refitting
11 Refitting is a reversal of removal, bearing
in mind the following points.
a) Tighten all fixings to the specified torque.
b) Where applicable, use a new securing clip
when reconnecting the fluid hose to the
pump.
c) Refit and tension the drivebelt as
described in Chapter 1.
d) On completion, refill and bleed the
hydraulic system as described in
Section 21.
