How to Rebuild your CA power steering pump

Post by SMKNG ACE »

I recently did mine and decided to do a little tread on this.
What you will need:

Cir clip pliers.
Spanner sizes 12,14,13,19,27.
Socket 12,14,13,19,27 short and long extensions with power bar and ratchet
Clean nylon rags.
New Power Steering Seal kit From Nissan.(R530)
2 New copper washers.
New Bearing size 6202 at Midas (R20) or other spares shop.
A bearing press or bearing puller (medium size).
New 2L of ATF Dextron 2 from any spares shop.(R120 )

1. Drain the power steering fluid from the reservoir.
2. Loosen the pump and remove the Belt.
3. Loosen the Banjo bolt size 27 from the pump and the supply pipe to the pump from the reservoir.
4. Remove the bolt size 14 witch hold the pump onto the bracket.the pump should look like this only with the pulley still on.

5. Remove the Pulley loosening the size 19 bolt and hitting the pulley with a small hammer a t the back of it Remember the pulley is splined so is the shaft be careful not to damage it or the treads.
6. Remove the 4 bolts at the back of pump to remove the back cover. You may need a engineers vice to do this.
7.Remove the inside center sections there will be a spring at the back of these parts.Remember to take note as the parts come out they need to be reassembled in the reverse order if you not sure consult the service and repair manual.

Part 2 of it.

9. Use a bearing press or puller to push or pull the bearing with the shaft out of the casing.

10. Now pull or press the bearing out from the shaft Make sure not to damage the splines or bent the shaft.
11.Remove the mechanical seal in the housing.( see above pic)
12. Blow parts out with air and clean the shaft .
13.Replace the mechanical seal using a socket or suitable tool to gently tap it in with a hammer. place some ATF fluid on the seal after it is fitted where the shaft will run.

13. Push the new bearing onto the shaft make sure not to damage the new bearing.Also DO push it almost completely flush otherwise it will cause the shaft to be to far back and push against the back shaft housing seizing it up or damaging the housing where the shaft runs.
14. Replace all the o-ring seals with new ones using a bit of ATF fluid to coat it for a seal at reassembly.
15. Put back the shaft in the pump housing pushing it with a socket down (do not worry about the seal to damage it there is a little shoulder for the bearing to stop.)
16. Replace the Cir clip back.
17. Replace the rest of the center parts.( in reverse order as taken out )
18. Replace gasket and fit the back pump housing.
19. Fit the pulley back and turn the pump. it should turn free by hand and not very stiff.

20. Fit the pump back and fit the banjo bolt with New copper washers and tighten tightly be careful not to shear the banjo bolt.
21. Replace pipes and fill reservoir with new ATF fluid.
22. Replace the Power steering belt. Not to tight as the tighter it is the more strain it puts on the bearing and in time could cause the bearing to fail.

All should be done.
