Hi all,
Some time back I started a thread about rebuilding a T86 transmission out of a Power Hawk. This is the link to that discussion: http://forum.studebakerdriversclub.c...ild-question&p
Brief history. Bought the car in 2012. I knew it had a shifting problem with 2nd gear but thought is was clutch/linkage adjustment or worn external parts. It would not quite go all the way in gear and would pop out if I didn't maintain substantial pressure on the gear shift. Over time it got worse and finally started popping out of send gear continually on compression. So...........
It has finally cooled down enough in Phoenix to crawl around in the garage without turning into crispy bacon.
So on Sunday, Oct. 21st, I put the Stude on my home made lift (2X12 w/2 1/2" screws) 
and pulled the tranny. It gives me appox. 12" lift. Worked great. I pulled the case cover expecting to see a second gear that was absolutely trashed and a syncro that was broken/mangled. I saw none of this at first glance. As I turned the input shaft what did I find but...... 
. Holy Crickey! This is third gear on the main drive shaft. This section of the gear broken off completely and is roughly 1 1/4 inches long. Now, this caused NO noticeable issues what so ever. Since the synchronizer sleeve slides right onto the remaining teeth and off you go. But this didn't explain my problem with 2nd gear. Upon closer inspection, I found....
. The syncro looks pretty good from a wear standpoint but the gear itself is extremely worn. Some of the teeth have been worn and rounded off up to 50%. So when I put it in second gear and a rotate the main shaft this is what happens.....
As you can see the syncro sleeve does not have enough of the gear left to remain in place, so it drifts back. Then as engine RPM and tranny RPM approach 0 load....out she goes. Anyway, just an update. I will keep this post up to date. Hopefully by the weekend I will have Lollipop back on the pavement.
Thanks again Jack Vines.

Thursday, 10-29, I go out to the garage and cleaned up all the external parts to transfer to the replacement trans, thank you Jack Vines. Took off the govenor, the solenoid and the shift levers moved them over and replaced the rear flange seal. I figured the trans had been sitting for many years, so it's the least I could do for it. Then tried to figure a way to use my floor jack as a trans jack. My first attempt was to set the trans on the jack, secure it with a ratchet strap binder and a little duct tape. Then got busy for as few days.
There was a significant leak from the OD Solenoid and oil was leaking from the shift levers. I had changed the tail shaft seal but none of the others. Please learn from my mistake! Do it on the bench, not on your back. And change the shift rod seals, OD lever seal, solenoid seal and tail shaft seal. Change them all. Getting the shift rod seals out was a witch with a B. So, I had ordered new seals from Studebaker.com. They went in very easily but still found I had a leak at the solenoid. Some previous owner had put the oil seal for the solenoid at the base of the solenoid shaft, rather than in the adapter plate. So NOW I am leak free........except a drip here and there from the hill holder unit. Rebuilt it once but still leaks a few drops.
