I just rebuilt my 1977 Ford poer steering pump and I have noticed something after putting it back together and I am not sure if it is correct or not. I removed the pulley to rebuild the pump and I had to drive it back on after reassembling the pump, since it is a press fit. I drove it on till the pulley flange was flush with the pulley shaft. I notice that the pulley shaft can move in and out ~ 1/4", is this normal? I never tried this before I rebuilt the pump, so I do not know if this OK or not. The shaft that slides in and out a 1/4" has gear teethon the other end and mates with the pump with complimentary gear and feels as though it still coupled whether pushed in or pulled out. When installed on the engine the pulley alignment has the pulley pushed in tight to the pump housing. I do not know how the pump is going to work yet,since I have not installed my rebuilt engine yet.
I have another related question reguarding this power steering pump. On my engine rebuild (1977 302) I installed a set of 1990 E7TE mustange GT heads and a new waterpump amoung other things, but when installing the PS pump using the original 1977 brackets and hardware I ran into an alignment issue with the other pulleys. I had to shim the pump in towards the engine ~ 5/16 and reduce the spacer thickness ~ the same amount and I had to shim out the water pump pulley ~ 1/16" to get all the pulleys to line up properly. The alternator alignment seems fine w/o any shimming. Anyone have this issue before? Having changed the heads and water pump I suspect that they may have caused the misalignment. Thanks.

I went out to the truck and tryed to move the pullely. Mine seems pretty tight, only got about a 1/16 of play, but the belt was still on it so that may not show all the play. I can not understand why you are haveing this happen if it is the same block. What could they have changed? Do you have the right brackets in the right spots? Erv

 

Most likely you ruined the pump and bearings by driving the pulley back on.

You will need to get a reman pump now and trade that one in for a core.

 

There are more than one application/design of PS pulley's.

What do you mean by "Drove it" onto the shaft?

Pulleys should be pounded onto a shaft.
There is a special tool (for $12.00 for DIY) that removes it and installs it.

I hope you have damaged the pump ?

 

Pulleys should NOT be pounded onto the shaft.

I think he did damage the pump.

 

That was supposed to say shouldn't.....as per the "special tool" I stated later

The word "have" should have been "haven't" in the last sentence.

I was obviously in a hurry when I typed that and didn't get back to it

Why didn't you just fix it Eric ?

 

I used the special pulley puller tool to remove the pulley, but the tool does not reinstall the pulley only remove it. In order to have a tool to reinstall the pulley the shaft would have to have a threaded hole in the end of it and it does not. The end of the shaft does have a hexogonal hole, which an allen wrench could fit into, but that does not help me. There are no bearings in this pump, only a long shaft bushing. Have any of the people responding to this question ever rebuilt one of these Ford PS pumps? The pulley is a press fit and I believe it was meant to be pressed on with an arbor press, but I do not have one of these tools, so I used a large rubber mallet to drive the pulley onto the shaft.

Ervin, I believe you would have to remove the belt in order to see how much movement the pulley shaft would have. When I installed it on the engine and tightened the belt it was much harder to move the shaft.

 

I've done about 5 of them.

I was talking about the R & R kit.

This is the snap-on kit

but there are cheaper kits available for the DIY'ers
Do you have a pic of that pulley.

There should be a threaded area on the end of the shaft.

 

There is a threaded portion BEHIND the hex part of the shaft. It is possible that there is gunk built up in the hole. The installation tool consists of a bolt that threads into the end of a shaft and a nut with a washer that threads down the bolt and presses the pulley onto the shaft without putting any load on the rest of the pump.

BTW- I have always been told that Ford PS pumps are non-rebuildable. Where do you get parts?

 

Well I'll be! There are threads behind the grease and dirt in that hex part. I really do not want to buy an $85 tool to put my pulley back on though. I got the rebuild kit from NPD for $9 and change. Thanks for all the help on Part "A" of my question. Any one have any ideas on Part "B" of my question on pulley alignment (See beginning of thread)?

 

I didn't expect you to buy an $85 snap-on tool.
That post was only for the picture of one.


If you read the rest of the post it mentioned buying a cheaper version for the DIY (Do it yourselfer.
Mine cost me $12.00.cdn

 

Sorry Mil1ion, after being in the garage all day I didn't have enough energy to finish reading your post! Actually I got as far as your SnapOn tool link and I clicked away to lala land. I found one on ebay for $15.99 BIN, so I will have it soon. Thanks.

Jim

 

I don't think the play is normal. I'm concerned that by driving the pulley on you damaged the pump.

Second question, I don't know for sure since you are using different heads, but I've never had to shim pumps to line them up. I'm wondering, did you possibly install the pulley backwards? The pulling hub has to be facing out.

 

I think the play I have in the PS shaft is due to the pulley not being on far enough. I was able to only drive it on flush to the end of the shaft. Now that I have been enlightened about these pulley installation tools I will use them to install the pulley again. I will first take it apart again to look for damage before I put it back together.

The pulley is facing the right direction w/ the puller groove to the outside. Thanks.

Well I disassembled my power steering pump to see if I could find out why the pulley shaft was moving in and out ~ 1/4". Well it turned out I caused this problem when I drove the pulley on with a BFH! The pump assembly fits into a cylinderical housing and is supported by two springs at the bottom of the cylinder. The bottom of the cylinder steps down to a narrower circumference and when I drove the pulley on I also drove the pump down into this narrower part and it got stuck there. I got the pump unstuck, reassembled the pump, and installed the pulley with the correct installer and the play is gone. One question though, how far are you supposed to install the pulley onto the shaft? Right now I have it installed, so that the tapered end of the shaft protrudes just beyond the pulley flange. Thanks.
