Started tear down and inspection today, she was funky inside, gears in good shape just the upper and lower bearings on worm shaft are toast.Haven't done one of these before but the step by step instructions are in the -34, how hard could it be?

Well if the fresh out of AIT E-2 screwed it up Uncle Sam just bought a new one. I don’t think he’d do the same if you do. Good luck! No pressure :)

Got a little painting done today, more of an experiment, i see lots of sanding I'm gonna have to go back and do. Finally got my front steering gearbox adjusted out about right. I don't have a lot of the special tools and adapters they used in 3rd shop back in the day when rebuilding these so I made do. My kit was in good shape considering it was boxed up in 79.

You have to pay special attention as you have to set the pre load on the the bearings and gears in 3 different places to get it right, pretty happy with how it came out. Doing leak test today, TM call for 10 psi for 10 minutes should be no leaks, I don't have what it takes to pressurize it, so just filled it halfway with 90 wt, and look for leaks, so far none.

My only worry it the top race on my worm shaft was pretty rough, tried to smooth it up best I could, but I have a feeling I'll be back in here in a few years, in the meantime I'll be looking for a new worm shaft to squirrel away till then.

All other gears looked great, the design of this box sucks, or I should say location, think I'll always try to park nose uphill to keep the water out.

If no leaks I'll put it back in tomorrow.

Happy 4th Tom.

Its been three years and you haven't finished? I thought it just needed the engine buttoned up and it would be good to go. What loser did you buy the hunk of junk from? :grin:

That puts grease between the shaft and bushing in the spindle. Not the wheel bearing,
Check the LO. number 6 in the notes.

By the way, that bushing is phenolic.
Trying to remember, I think this was discussed here some time back, is this grease zerk on top of the hub just for post fording operations?

I am going to disagree with the lube order on this one. Here is a picture of a spindle assembly, you can see a black dot if you look directly below the grease fitting. This is where the grease comes out, not on the spindle shaft but on the inner bearing. If you pump grease in it's going to blow grease by the seal and you will have grease all over your brake shoes. Pack the bearings by hand and ignore those grease fittings. Originally they probably were to lube the spindle but some how the drawing was incorrect and the hole was drilled in the wrong location, hard to say.

Looking gooder and gooder…….I noticed the wife or kids put an additional thousand miles on it according to the odometer when you weren't looking.

Not real sure what this picture shows but that hole admits air from the engine air box to pressurize the brake drum. Check the connection ports on the spindle and make sure a zerk is not threaded into the air fitting, they are marked. It should be zerk, Hydraulic, air, on the drivers side. My zerk goes to the spindle bushing, a phenolic bushing that is supposed to prevent water from entering the drum. Suggest blowing air into that zerk fitting hole to see where it comes out. The markings for the air and hydraulic fittings are stamped into the metal at each hole.
