How do you remove the power steering pump on a mini?

Answer 1

Tools and supplies needed:

10, 13mm sockets with ratchet and extension(s)

Medium side-cutters (6" or so) to remove the crimped hose clamp.

Floor jack and pair of jack stands

New hose clamp

Small screwdriver to release the tabs on the power connector

Medium screwdriver to install the new hose clamp

Drain Pan to catch the mineral oil

1L can of Pentosin CHF 11S

Optional: new O-ring for the high pressure line

De-greaser to remove spilled oil

Procedure:

1. Remove the two 13mm nuts that attach the fan bracket to the PS pump bracket

2. Disconnect the fan electrical connector and set the fan assembly aside.

** This would be a good time to check the fan to make sure it spins smoothly and easily.**

3. Remove the two connectors from the PS pump. - The small connector has one retainer that can be released by squeezing the tab toward the connector body. - The large connector has two tabs that need to be released by gently prying them away from the connector body. It is easy to break these tabs.

4. Remove the hose clamp from the hose that goes to the reservoir. Since it is crimped on it can be a PITA to remove. I have successfully at removed these by putting a screwdriver in the crimped area and prying the crimped area apart. YMMV

5. Remove the 13mm bolt that holds the high pressure line to the pump.

6. Position the catch pan to catch the oil that will spill when the hose is removed from the pump. - You may want to have some rags handy to keep the oil off the sub-frame. Clean up will be easier this way.

7. Remove the two hoses.

8. Remove the 13mm nut and the two 13mm bolts that attach the PS pump bracket to the sub-frame - The two bolts are visible (barely) at the rear of the sub-frame in the area of the down-pipe.

9. Drop the pump far enough to remove the wire retainer clip.

10. Remove the pump.

11. Remove the four 10mm nuts that hold the pump to the mounting bracket.

12. Installation is the reverse of removal.

The thing that was the most frustrating was the removal of the low pressure hose. Everything else was pretty straightforward. If you have everything ready to go, it should only take about 1/2 hour or so. Partly depends on how difficult it is to remove the hose clamp.
