: Power Steering Pump rebuild

Hello Fellas,

I have a 70 Monte with a 454 and am planning to install the power steering pump back in. The unit is from a small block and it is the teardrop style.

I could buy a rebuilt pump but CarQuest wants $120 for it. Since I have to start being a bit more financially responsible they offer a rebuild kit for $25. I am going to look at the overhual manual tommorow and try to figure it out. In reading the chassis manual it seems first of all you need a special tool to pull out the pulley. There are 2 types of pullers one for stamped on # and the other for no stamps. Are these pullers still available?
The hoses are also pretty expensive and I was planning on going to a hydraulic to get some made from braided steel.
I am hoping to not rebuild the steering box. It doesn't leak butI haven't driven the car yet. The car has 99000 miles on it. The fluid in the pump isbrown so probably the fluid left in the box is bad too. There is a section in the chassis manual about bleeding the system but I assume you are mostly bleeding out the reservoir.
Anyone rebuilt one of these?

Thanks,

Kris

I rebuilt mine.

I think my pump was switched with a 70's model, since the rebuild kit for the 65 didn't fit, but I traced the main front seal to one from a 70's rebuild kit. It has the key'd pulley and integral tank.

My rebuild was easy and required no special tools. I think I used a generic three finger "puller" from harbor freight to get the pulley off.

I just installed an AGR box and their bleeding instructions consisted of putting the fron up on jack stands and turning the wheel lock to lock about 50 times, or until the resivour (SP?) didn't have any foaming (bubbles).

Thanks Charles,
I will try using one of those 3 finger pullers. CDN tire has a "loan a tool" program that
I can use for free. I looked at the overhual manual and it looks pretty simple. We really have
a lot of old manuals dating back to 1950's here at the Library. It is pretty interesting looking at how things developed from 1950-1973.

Might want to be careful with the 3 jaw puller. I think a few people have bent the pullies.

I ended up using a Lisle puller tool that worked fine. I misread the instructions and tried
to take it off without removing the retaining nut. There are a few chunks missing
but enough to take out the pulley. The pulley has one small bend in the channel I assume this is nothing to worry about. I basically have everything apart now and have learned a lot.

The real problem is 2 small pieces (1 vane,and the woodruff key) feel off my workbench and into a box of nails. I really hope I can find them maybe the rebuild kit has some extras in it.
If not I will have to buy a rebuilt pump unless I go a yard and buy a used pump.

Check with your local NAPA parts house. I just rebuilt my 72 pump with one of their kits. Good directions and complete parts. Kit sold for 15.00. I just used a small two jaw puller to remove the pully. It came off very easily.

The puller came out easily but the problem now is that I lost a vane from the rotor and also the woodruff key. I don't think it is in the rebuild kit so I am searching for other places to get it from. A GM dealer can't get them and a machinest would charge about $50. to duplicate the part. Next I will try a hydrylics shop. I remember when I was a kid building models small pieces used to fall on the floor and I never could find them and now the same thing happened to me again.

Well I just completed rebuidling it. My Dad took a look and found the small pieces (vane&woodruff key) I am very lucky having a father with good eyes.

The only part that was a bit hard to figure out was where the seal bewteen the flow control valve and the union go. I just put it after the flow control valve.
I think it will work fine. I hope one day I can help out a fellow TC member with this rebuild.
