Wusty Welic ... wonderful!

[Mike K]

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 ?
