Balance point for a G54/TC combo?

Balance point for a G54/TC combo? - 05/15/13 09:35 PM

My rear main seal just blew out, so it looks like I'll be pulling the transmission off to fix it.

Has anyone figured out the proper spot to jack up the tranny/transfer combo for a roughly 50/50 weight split?

Thanks

I have a harbor freight tranny jack (use my electric impact to lower/lift), so that helps. I put it just in front of the TC. Not much weight in the bell housing.
This is also without the cross member attached.
When swapping out my brother's Tranny/TC, by fluke, we found that jacking the rear end up and suspending the tires about 2-3" off the ground, and leaving the front tires on the ground, made it so when the engine leaned back against the firewall, it was actually LEVEL with the ground.
That made the r/r of the tranny so easy, we didn't even start the 4letter words!
I was expecting to have to lift and slide forward the whole thing, but it just slid right on. Took us by surprise.

Hope this helps,

Todd

Good call, that's definitely a stable point to put the jack on. Now though, the jack doesn't go low enough to get the tranny out from under the truck to clean it off <img src="/forums/images/graemlins/scared.gif" alt="" />

And the education continues…

If I remember correctly, we were able to rotate the trans 180 while under the truck so the bell housing came out back by the rear wheels. He has 31" tires, not sure if that makes a big difference though. We did remove the shifters (assuming you did as well) as well as the rear drive shaft.

Wound up using ratchet straps to hang the tranny while I got the jack out, then lowered it onto my creeper with a couple boards on top. Slid right out then.

Resurfaced the flywheel, changed the rear main seal, put a Marlin HD clutch and short throw shifter in. Put everything back in and changed the Tcase output shaft seal. Got it all buttoned up around 9 this morning. All together, maybe 16 hours of work or so. Not too bad for doing it completely myself, for the first time, too.

NAPA sells some fantastic degreaser in a purple bottle. 25 years of oil and dirt came off with a little scrubbing, and it's shiny aluminum except for a few spots.

The adapter to turn a regular jack into a transmission jack worked OK.

I'm sure a dedicated jack would have been a little easier, but I made it work. The angle adjustment was nice for getting the transmission back in. The single bolt attachment point seemed a little cheesy, but nothing broke so I guess it works.
