Hey guys,
Ive recently rebuilt one of these power steering pumps and i thought i would write up a guide with a few photos and show you how to recondition your own pump! these things are dirt cheap anyway but i had a streak where i went through a couple so now ive got a reco one in the shed ready for when i need it.
Its really not hard at all it is quite simple actually, you only need some simple tools but i must say if you dont have a G Clamp, 1" spanner or socket, assorted screwdrivers and pliers its going to make it ALOT more harder to get into the pump.

Tools Needed:
Hammer
G Clamp
Needle nose Pliers
Assorted Phillips and flat head screwdrivers (Big and Small)
1" Socket and a ratchet to fit the sucker or spanner
Bench Vice (depending on what you have around)
Air compressor or something to blow out the gunk.

Other assorted items:
Power steering pump rebuild kit (Comes with seals and a bearing)
A dab of power steering fluid
A couple cans of degreaser
Clean Rags


**Refer to this picture if you dont know what each part is called, or lost what order things go back**

1. First thing is to have the pump removed from your car unless you've gone down to the wreckers and picked one up to rebuild just to have as a spare. There's a few write ups on here about removing the pump from the car its not hard at all its 2 hoses and 6 bolts.

2. Once removed get a nice clear space and put an old towel or rag down and find a suitable container to sit the pump in as its still going to have fluid in it

3.Get hold of your G Clamp and like the pictures below line the clamp up over the allen key bolt on the front and the bubble groove on the back plate of the pump and tighten the sh#t out of it so it compresses in but try to keep your clamp straight otherwise it will compress wonky, after that leave it clamped down

4.With the G clamp still holding it down find the small hole on the outside of the pump, it may be filled with grease and crap but its right here on the pump
401485_4723706815707_919637402_n_zps25b8723d.jpg

After you find the hole put a small screw driver into and push and youll see the snap ring being pushed out a bit, grab another screw driver and get it out just watch your eyes mind had a bit of force when coming out.

5. Once you've gotten the ring out slowly undo the G clamp and move it out the away, now the back plate may be tight as or yours may be loose already if its tight just give it a tap with ya hammer and pull the back plate out it should look like this.

Pull the spring out and start to put your parts away in a SAFE container.

6. With the spring out you just have a plate starting at you
2012-09-06184332_zpsff36dbc5.jpg

now do this next part over a container cause parts can go everywhere, grab the pump and OVER the CONTAINER bang it on your hand if nothing comes out the pump bang it on the table but in the container, im serious i had sh#t go everywhere, keep banging the pump in your hand till no loose parts come out you should have a pressure plate, a ring, 10x vanes, 2x pins.

7. Now your looking at the rotor and a little circlip
2012-09-06182930_zps0fae6e14.jpg
2012-09-06182941_zpsc774e3b9.jpg

this is where you will need a very tiny flat head screw driver and a hammer, pretty much just hammer the little screw driver into the circlip and try pry it out a little bit, when you get a little gap grab another screw driver and pry it out, itll be bent back later so dont worry bout it being a little misshaped but if you completely bugger it just go to wreckers and grab another.

8.With that little clip removed pull out the rotor.

9. Pull off the thrust plate, it should just fall out.

2012-09-06184809_zps6fd45802.jpg


10. Rip out the main shaft of the pump just grab hold it from the front and back pull, other cases may need a tap from the hammer but mine come out pretty good.

An overview of all the parts ripped out so far
2012-09-06184928_zps1084be01.jpg


11. Grab your 1" socket or spanner and undo the bolt on the back of the pump, i dont have a vice but i did a mission trying to undo this bolt i have heavy sleepers of metal in my yard and there was a slight hole under the sleeper just big enough to jam the pump in wrapped up in a rag (accept for bolt exposed) and i undid it that way if you have a vice you are laughing if not im sorry you gotta improvise like i did.

12. After the bolt comes off a spring, a valve will come out also, chuck all of it your container accept the housing for the pump and fill it up as much as you can with degreaser
2012-09-07145942_zps3e4890aa.jpg

i dont know why but i threw the old bearing in there lol!

13. Take the housing back to your bench and put it facing upwards toward you, you will see a bearing pry it out with a screw driver or something but dont go psycho on it youll see the bearing in the picture below
2012-09-06185140_zpsc08a0d14.jpg


14. Pull the seals out the pump housing you'll see them on the walls of the pump there will be 2 of them also pull the seal off the 1" bolt valve, now chuck your pump housing in a container and fill it with as much degreaser as you can
2012-09-07145948_zps2bee7c17.jpg


I let all my parts soak over night, and then in the morning i blew them out with the air compressor and then let them sit in the sun on rag. I then decided to re paint my housing so i sandblasted it back and resprayed me housing

Partially blasted back

Finished Blasting
2012-09-08112823_zps8086cc23.jpg


All rust primered
2012-09-11173335_zps94e8fa03.jpg


All sprayed black, wanted to do silver but didnt have it.
2012-09-24082013_zpscf7285b1.jpg


All set up and ready to put it back together (minus the housing it was still drying at this point)
2012-09-23164528_zps07096936.jpg


15. Grab the seal kit, and pour a little bit of steering fluid in a container
2012-09-24081844_zpsf30bf50f.jpg
2012-09-24081700_zpsa0c051e5.jpg


16. Grab your new bearing and lather it a little bit with steering fluid and put it in the pump where the old one come from, youll need to tap it in with ya hammer but make sure you got something between the bearing and hammer and dont bash it in.

2012-09-24082243_zps2d7ad0cc.jpg


17. Grab one of the big O rings and smear some fluid on it and put it in one of the 2 O ring spots, just seat part of it in and run your finger round in a circle around the pump to make the rest follow in the groove, put the other O ring in the second slot when your done. (Do not put an O ring in the very last groove towards the back of the pump that is where the snap ring goes)

18. Install the main shaft for the pump and if its a bit hard just lather her up

2012-09-24083034_zps1f9f8160.jpg


19. Chuck the thrust plate in, dont worry it wont stay there until you secure it in with the 2x pins, they simply go into the small holes under the thrust plate.

2012-09-24084319_zpsae4124fb.jpg


20. Get your rotor and slide it over the shaft and put your circlip on, just use needle nose pliers and squeeze it back to shape around the rotor shaft after that start putting all your vanes in

All installed on the rotor
2012-09-24085555_zps10bb1c76.jpg


21. Install the Ring over the 2 pins it will slide straight in
2012-09-24090031_zpsd7ca6acd.jpg


22. Chuck the pressure plate over the top of the ring
2012-09-24090224_zpscebd76b5.jpg


23. Chuck the spring in place and the back plate, now the same as earlier use the G clamp to clamp it down and put the snap ring back! its alot harder then taking it off. i scratched up the back of my pump with the G clamp :(

The cork crap didnt work to well i just did it without it
2012-09-24092754_zps8bfc47e6.jpg


24. Grab the 1" bolt valve thing and put the last seal out of the kit on it, once you've done that put the spring in the hole first, then put the valve in and then the 1" bolt valve. Tighten it up **PLEASE NOTE, MY O RING ON MY 1" BOLT VALVE IS IN THE WRONG SPOT IN THE PICTURE, IT MUST SIT IN THE GROOVE ABOVE THE THREAD CLOSEST TO THE END OF THE BOLT, I DIDNT HAVE A CORRECT PICTURE TO REPLACE IT.**
(can be a bugger to put back in as well)

Nice write up. On top of the seal kit you can also by a rotor vane kit as these parts wear out as well.

If you have a good look at the pictures you can see some wear on the rotor vanes, these can be turned around so that you get another use out of them. I've done this but the pump is still a little noisy :(

VN Series 2 engine...
First up thanks a load for this write up I have just used it step by step to do the rebuild on mine, easy as to follow, beats paying someone else when it is pretty simple when you know how!

Only thing I noticed was where you have put the o-ring on the valve thing in point .24 of the write up seems to be in the wrong place... When I took mine apart the seal was on the bolt side rather than the thread side....check out your pic of all the parts in the plastic box you can see where the o-ring should be..

Thanks again, I was just about to order a rebuilt one when came across this write up.

anytime mate, it is certainly pretty easy! i did realise my o ring is on the wrong spot on the valve 1" bolt, just didnt have another picture :/

ill edit the post to make sure it says its on the wrong spot!

glad it helped you

Thanks for your write-up. My power steering fluid has been leaking for some time but I couldn't see where it was leaking from. I have done a pretty thorough degrease form underneath (car jacked-up and on stands), then gave everything the once-over with the high pressure gun.
Then I decided to replace the rocker cover gaskets and inlet manifold gasket. With all the "extra" bits off the front of the engine I could now see "red" oil on the pump mounting bracket. More stuff to take off and finally I see where the power steering fluid has been leaking, from the rear seals. This has been leaking for some time, but not that I could see, and running down side of block to rear cross-member, then on to drip tray.
Now with your excellent tutorial, I will dismantle the pump and fit a seal kit.

Cheers, Jet. :beer chug:
