Wusty Welic ... wonderful!

Your are fortunate to have a gearbox that is in good shape, many of them are stuffed . The later wartime T84 gearbox ( think it's the H type) have a seal at the rear end of the main shaft, this was an attempt to alleviate the transfer case oil migrating into the gearbox. There was a oil seal kit available during the war, mechanics could retrofit the seal into earlier gearboxes. Many restorers fit a modern double sealed rear bearing, but the little breather cap on the transfer case front output casting/cap needs to be functional otherwise pressure will build up and oil will be forced out through the seals. G503 forum has many posts on all this.

The chunk of metal may be from a shift fork ?

Article is from Dec. 44

I think that the chunk of metal is a piece of the cage of a ball bearing.

Thanks, Mike, for the article. I have a new un-sealed bearing for the gearbox (came with the spares), but will now purchase a sealed bearing for that rear position.

David - could be, but don't know what it started life as, just know it's not going back into this transfer case re-build!

Spent yesterday finishing off and undercoating lots of small stuff and getting the chassis finalised and ready for the sand blaster.

The axle housings went off to the sandblaster yesterday, suitably shrouded to avoid getting grit inside and masked to prevent sandblasting of the polished surfaces. Dismantling the axles was an interesting process - you know there is a problem when you take off the rear cover and bits of chewed-up steel drop out! A carrier bolt and keeper had come adrift at some stage, and been chewed up by the crown wheel & pinion, but surprisingly, neither have any visible damage. The bolt and keeper are another matter - I might have to replace them!

Yesterday I had to do a woodworking job on a treated pine post to erect another bird nesting box for the local Wood Ducks and Hooded Mergansers, so stayed with the theme and finally made an axle rack, neatly tucked out of harms way next to the work bench. This should reduce the risk of damage to threads and splines while in storage. It safely stows the axles from the current project, plus the spares for both the MB and GP.

The stacks of finished parts, ready for re-assembly, grow: the image shows one of three such stacks. I've also created a database listing of parts I'll need to purchase - that continues to grow, too!!

I see you have the later type transfer case housing . Reading the G503 forum , I found out that the housing was changed during WW2 production, this change was done in order to minimize the amount of oil splashing out of the breather cap .

Yes, fortunate to have the later variant of T/case. Don't think I've ever had an early one in three or four jeeps. I'd probably have known by the pool of oil!

I also have the still later variant with the 1.25 inch diameter intermediate gear shaft, which is in the spares box.

In case you don't know this:

There are two special dowel studs that locate the steering arms onto the steering knuckles . It was discovered that the steering arms were working loose so they came up with a fix bulletin.

The dowel studs have a 3/8" wide middle section . RFJP doesn't have them, I will make some myself on the lathe.
