4.10 REMOVING AND INSTALLING STEERING PUMP

Note:

When replacing a worn steering pump, you are

advised to fully drain the steering oil and replace

the steering oil reservoir and integrated filter.

In extreme situations, the steering pump may

have been worn to such an extent that metal

pump parts have entered the steering box. Check

the steering box for internal wear using the test

case.

Removing steering pump
1.

Clean the line connections.

2.

Place a receptacle underneath the steering

pump.

3.

Remove the lines from the steering pump

and plug the line and pump openings. The

filter is fitted in the return line, which means

that should any dirt enter it will immediately

also enter the steering gear.

4.

Remove the attachment bolts and remove

the steering pump (3) and the driver (1) from

the compressor.

5.

Remove the reservoir (4) from the pump (3).

Installing steering pump
1.

If necessary, fit the bracket (2) on top of the

new pump. Do not remove the cover from the

pump to do this. Tighten the attachment bolts

(1) evenly to the specified torque. See

"Technical data".

2.

Check the driver (1) for wear.

3.

If necessary, connect the line couplings to

the steering pump to be fitted. Tighten the

couplings to the specified torques; see

"Technical data".

If the specified tightening torques

are exceeded, the aluminium pump

housing may be damaged.

4.

Fit a new O-ring (2) on the steering pump

and grease it lightly.

5.

Crank the engine until the compressor driver

half is horizontal.

6.

Grease the driver (1) lightly and fit it to the

compressor driver half.

7.

Fit the reservoir (4) on the pump.

8.

Fit the pump (3). Tighten the attachment

bolts evenly to the specified tightening

torque; see "Technical data".

9.

Fit the lines.

10. Fill and bleed the steering gear hydraulic

system.

11. Take a test drive and check the pump and

line connections for leaks.
