Good parts haul off the old dumper

Was breaking down the rear bogey and was amazed at some of the parts I got.

The rear drum was held on by 3 countersunk hex head screws that were staked in place. Had to drill them out. Good thing the hex head made a good pilot hole for the 1/2in drill. My truck has slotted screws, we'll see what the other 3 drums have on them later.

My $20 harbor Freight pneumatic drill. I really like the Dewalt bits with the starter tips.

Those lining look brand new. They are bad though.. the drum wore uneven and the linings had a significant taper to them. But the red oxide backing plate, axle and shoes do show that the inside of the drum is primered only (like the jeep). They are post war parts.. the lining were held on by brass rivets. Wartime brake shoes switched to steel rivets.

And the reason for all this work.. one brake cylinder with adjusting ends... I have no idea what the insides look like and I don't care.. a sleeve and its brand new again.

Here are the cups.. notice that one is original BENDIX the other is French. Seems that non-usgi parts hold up quite nicely.

The split axles had some odd plates on them:

First was this one in French:

Blah blah blah??? Gonna have to Babelfish it and see what comes back.

Here's one in in the casting:

Not sure if this is a GMC original part or not. Will have to check my other splits and see.

All in all not a bad day. About 3 hours to tear it down to this point. Lots of heating, banging, drilling etc. But the other side and the other axle should be quicker now that I know what to expect.
