Transmission stud repair?

Hi all,

well I found the reason why all the tranny oil ended up on the garage floor...

Can anyone recommend a good shop who can repair this in the Philadelphia Area?

I'm assuming it'll need some welding and re-drill/tap the stud hole.

This is a two (or three) step repair.
Remove both tranny shafts.
Weld hole shut, check yellow pages, welders, aluminum.
Drill and tap hole, check yellow pages, engine rebuilders (or a good garage).

Hopefully with the heat from the welding it does not distort the case and upset the alignment of the bore . Those shafts need to run through the case in a straight line. I have used dry ice or at the least wet rags around the area that is being repaired to keep the heat localized to help with the distortion issue. I can see also that the seal has been squeezed on the outside edge with a chisel or a screwdriver to make up for the oversize hole the seal presses into. That is OK, cause "Old Hogs" are like "old tractors", they just keep on runnin' but you may end up needing a fresh case with the problems you have to avoid issues in the future. Just saying...

"Staking" the main drive gear seal was standard practice from the factory and was recommended anytime you replace the main drive seal per the manual. Later seals don't require this practice anymore. Here is a photo of my 1946 4 speed case and you can see where the seal was staked in 3 spots.
