Attempt to make some progress on the tub. I'll grind off the slag and what not later on.
Removed the MC and dropped the T84/D18. Holding off on body work as long as I can. I have a leak coming from the pto cover so I'm picking up something to fix it.....
This should cure the leak....
Started to clean up the winch. It's a Koenig C-100. It's missing the mounting bracket and lever. I did a little test fitting with the pto and everything should clear the exhaust and axle fine.
Got the grill stripped down and separated the t84/d18.
The T84 is from a slat grill Jeep. Date code C17-42 which translates to March 17, 1942
Here is the D-18 main shaft gear. note the half F-script stamp.
So I found whats left of the front countershaft trust washer in the bottom of the t84 and we got some countershaft gear carnage. Overall I guess the transmission guts are in pretty good shape for being 75 yrs old.
Awhile back I did some measuring before the tub and all was removed; planned on staying with 750-16 but was gonna go with ndt's and combat wheels.
GPW fender clearance with 750-16
~ 5 1/2 inches to top of front fender
~ 5/8 to 11/16 clearance between tire and leaf spring.
~ 2 1/2 inches tire to tub right rear behind passenger
~ 7 15/16 inches clearance to top of rear wheel well
Got the d18 tore down and the intermediate shaft is shot (as I suspected). I plan on driving this unit when it's done quite a bit and would like to keep downtime to a minimum. So my question is go with a Novak intermediate shaft or is there someone else I should take a look at?
*The intermediate shaft is 3/4
Started cleaning up the gas tank. It's not the correct one for this GPW but since they are $400 I'll keep it. The fiberglass was a terrible idea
Got some dualmatic hubs yesterday and cleaned the T84.
Novak has the best shaft available AFAIK. Others are not hardened or not properly hardened and known to be problematic. Finding one NOS is another option. I was pleased with Novaks kit.
The G503 transfer case had a 3/4" intermediate shaft. Later jeeps were subsequently upgraded to 1 1/8" and then to 1 1/4".
If you were to find a different case, closely check the transmission to TC face to make sure the countershaft properly clears the TC. Years ago, I obtained an NOS WW2 transfer case (this was around 70-71; Border Parts had it for $60) to put behind a T90 in a Cj2A. I had to have the TC machined to clear the countershaft where it stubs out in the rear).
Got the T84 primed and ready for paint. Got some bearings for the T84 and D18 just need to get another cluster gear and everything can start going back together. I figured the bearings wouldn't cost so much but I was wrong.
D18 cleaned up nicely
Something went amiss on your last post...something about your photobucket account....
I am loving this rebuild...please keep posting...
Got some more parts cleaned up the other day. Trying to keep the ball rolling.
