Blown O Ring/Seal - Strearing Box

This happen to anyone else? I am having a problem getting the gear box out. I have everything loose, just not coming out. Do you need to take off the stearing drop arm to get it out?

I still never even knew oil was in there until it started leaking. Sure is clean oil...looks brand new. Kind of a lot of oil for what it is for....

If your talking about the pitman arm, yes you do have to remove it, you'll need a pitman arm puller and if its stuborn like mine a good heavy sledge hammer. The puller wouldn't pull the arm off even with agressive torque on the screw. But a good solid smack with the sledge, combined with the load of the puller, loosened it right up.

Also instead of pulling out the horn wire from the steering shaft, look for a in line connector at the base of the steering tube where the wire comes out of the bottom. I know mine had one not sure if it is on all Pinz's.

Thanks Miles. Thought it wouldn't be that big of deal but I guess I was wrong. Guess Im on the look out for a pitman arm puller. I already have a BFH. Don't leave home with out it.

That seal behind the Pitman arm is the same as a Mazda 626 camshaft seal if you get stuck for one. I get mine from Carquest. Just give them the size to ensure you get the right year.

Are you talking about the seal that is on the outside of the truck? That's awesome. Thanks

Yes I refer to the seal inside the extn housing.
Basically the box has a long shaft on it that is covered by a cast alum tube (the one you see inside the cab and it protrudes just out of the floor pan on the underside to reveal the pitman arm.
Removal of the arm should allow you to slide off the dust boot to reveal the seal I was refering to. Don't forget to put some oil back in the tube once the job is completed.

just rebuilt my steering box on my 712. I had a small leak at the lower end. I purchased the rebuild kit from SAV. It is a complete set of shafts/bushings and seals. Removal of the old shafts was a pain as they were bent and had to be cut in two for removal. Now with all new parts it drives well again and no leaks. Most of the auto parts stores will loan you the pittman arm puller or rent it for a very reasonable price. The puller is not all that expensive anyway.

I guess I will never know, but after taking it all apart I might of not even of had a leak. Most all the bolts were barly hand tight. Doesn't seem like a big deal, just a pain when you have to look for tools.

By the way, what is the nut size on the pitman arm? Not the crown bolt-the other side. It was over 24mm I think.

Don't have it in front of me but I think it was (42mm or 1 5/8")-correction.

It is the only bolt that I have found of this size so far while dismantaling my Pinz for restoration. It should be easy enough to find a box end wrench in 1 5/8" size or a large crescent wrench should work just fine.
