This is the second part to my Saginaw 800 series steering gear rebuild how to. With information on rebuilding the Saginaw steering gear being very vague, incomplete and hard to find. I'm hoping this how to will aid the backyard mechanic with the proper tools to successfully service their Saginaw steering gear. To aid in the assembly you will see I fashioned a board that attached to the mount holes of the steering gear so i didn't have to place the gear in the vice after i had painted it, yes I'm anal about those things along with keeping parts clean prior and during assembly too.
If your attempting to service your Saginaw steering gear and encounter worn out components, DO NOT REUSE THEM!!!, obtain replacement parts that are good and use them instead, or use a JY box and rebuild it instead!!!, throwing bad parts at a good project will only yield bad results!!!
Now on to the fun part!!!!
With the tear down complete I started in on the cleanup of the various parts and further inspected them for any damage, I couldn't find any with the exception of some minor grooving from the old seals on the sector/pitman shaft of which i sanded down most of it being very careful not to touch the needle bearing surface, i was able to eliminate 95% of the double lip seal groove and about 75% of the single lip dust seal groove, enough to not damage the new seals.
I glass bead blasted the steering gear housing in preparation of painting it.
I made certain not to blast any of the critical internal sealing or hydraulic surfaces. After masking all surfaces i didn't want painted i always do a little trick that has worked extremely well over the years and this is to use a propane or map gas torch to heat the metal up to evaporate any moisture that is resident in the metal, yes metal can soak moisture in and is huge cause of paint work bubbling up due to rust!. After its cooled off i proceeded to shooting the primer and color on.
I received the rebuild kit and laid out all the o-rings, seals, Teflon rings and related hardware in preparation for rebuilding.
A side note..... check all your rubber parts for softness as you lay out the parts, some have reported getting defective rubber O-rings that were very hard and or brittle.
Some of the assorted tools ill be using in the rebuild.
Let the rebuild begin!!!!!
First thing to do is press in the sector/pitman shaft bearing. (NOTE*) the lip side is up and the bearing is pressed from the bottom side of the steering gear housing as shown.
