Re: '46 Chevy Shorty

Thanks Jack --- and Roger working out the sequence of things. Good example are those rear window frames. They were single piece affairs that hosted both the quarter round and the rectangular glass in front of it. My plan included deleting the rectangular glass on both sides with steel inserts welded in place. At the last moment it occurred to me that if I ever had to replace the remaining quarter round glass there would be no way to do it. I wound up having to cut the existing frame then build a support for the delete that is separate from the other part of the frame.

Got lucky on that one. Who know how many similar issues I will discover I missed down the road.

Oh well, as they say in Galaxy Quest...

Onward!

Re: '46 Chevy Shorty

DammmitDammitDammmit!!! --- just discovered that the new Dana 80HD axle has a bent lug bolt. Tried fitting the new rim and it slipped right on one side but the other wouldn't go. Measured all the lugs and somewhere, likely in transit, one lug got whacked hard enough to throw it off about three millimeters. And from what I can tell, doing it right and replacing it requires tearing down the freakin' axle. It appears it cannot be put in place without major disassembly.

Therefore...

I plan on trying to heat that sucker and whacking it BACK into position. Wish me luck.

Re: '46 Chevy Shorty

Hey Tango. Before you go further I'd suggest that you jig up the axle and check it for runout from several points. I rebuilt a Suburban roll over once upon a time and had the same bent lug problem. although the lug was no problem to change out, it turned out that the accident had caused a bent axle flange--which I would have picked up on had I done a runout test. Fortunately, replacing the axle shaft solved the problem. Can you find out from the place (person) you bought the rear end from about its history? Not good news but better to find out now rather than after the bus is all new and shinny and you are in the middle of nowhere on a camping trip. Jack

Re: '46 Chevy Shorty

Thanks for the info Jack --- I had it gone over by the top axle shop here in town when I re-geared it. They said it was in great shape (?). That said...the lug bolts were not on the check list and the one problem child is not visibly out of line. I had to mike them to find the culprit. May have happened in transit from the re-builder. He was a bit of a dufus who drug it around pretty hard unloading it.

Let's hope that's all I find. Next stop after picking up a few nuts for it...the torch and a big-ass piece of pipe.

Re: '46 Chevy Shorty

tango, can you loosen the backing plate to get clearance for removal/insertion?

Re: '46 Chevy Shorty

Howdy claydbal --- Being totally unfamiliar with this axle other than it's specs & reputation, I plan on going by a Chevy dealer after Labor Day to see if I can find a trick on replacing these puppies. Years ago, I would have assumed there was no way a manufacturer would engineer anything so stupid as to require major disassembly for a minor and vulnerable part...but these days?

And, don't even ask me about changing a frikkin' headlight on a #%&# !Toyota 4-Runner!

I'll let you all know what I learn.

Re: '46 Chevy Shorty

The "trick" used to be a lugnut (to protect the threads) a little heat, and a BFH. Not approved but never had a failure as long as the threads were still true.



Or get out the special press tool. Basically an overgrown C clamp with a hole in the backside to press out the stud.

Sometimes parts stores have this in their free tool rental.

Re: '46 Chevy Shorty

Roger the lugnuts & BFH --- Problem is still that the lugs are too long to remove without major axle disassembly. Hoping someone at the local Chevy house can provide some kind of shortcut. Otherwise, it's oxy acetylene & a BFH to try and whack it back where it belongs.

Thanks to all for the tips & support.

Re: '46 Chevy Shorty

Is there a place on the backing plate with a big enough open space to bore a hole, or is the axel flange also in the way?
