PSB Links?

[Shawn]

Anyone have ant good links on how to rebuild a saginaw PS box?

In looking at the cruisers box,,, I see that both the pitman seal and the input shaft seal are leaking...

anyone?

I don't have any links or informal manuals on hand, but saginaw boxes really aren't that hard to rebuild. The hardest part is getting all the little balls back into the worm gear assembly correct. It probably took me about 10 tries to finally get it right.

To get started, pull the sector shaft and all the seals from the top of the box. Then tap on the round aluminum end piece with a rubber mallet to give the inner clip some room, use a punch through the small hole to push the large c-clip out, then cycle the input shaft and it will push the end cap out. Be careful not to go to far if you don't want the balls to fall out all over the floor. You really don't want to lose any of those.

Another thing to watch for, when you go to put the piston back in you are very likely to tear one of the seals on it. Stupid sharp corners on the box housing... Use lots of lube.

Also, when you go to put the sector shaft back in, make sure everything is centered and aligned. It was pretty simple. I think that there were alignment marks inside the box, but I don't really remember.

The stealership has a tool that is supposed to make this part a piece of cake

Here is a write up of the rebuild

Thanks Zog,,
Is there a reason to tear the box all the way down?
I was just going to replace the seals and the pinion shaft bearing. Are there more bearings inside some where?

As long as you are into it why not port it and cap the ports incase you ever decide to run hydro assist.

I will be.

I will be.

Are you going to port the caps or the main body? I think you will have to disassemble it all the way if you are porting the main body, otherwise you will have shavings kicking around in there

 

[Herzog]

yeah, if your going to port it, tear it completely down. That is, if you going to port the housing and not the caps.

I had some pictures on my computer from when I did this, but I can't find them anywhere...

Anyways, if you're just replacing the outer seals, then that is cake. I think the input shaft seal is just behind a c-clip or something.
