jig tool looks necessary to me.

I'm willing to assist as needed. feel free to borrow my press that has the modified "table" for pressing large gears.

Jig definitely looks necessary for a one-shot re-shim. Not sure I could fake that with some accurate measuring method and playing it with different shim options and measuring endplay sounds dumb. I need the actual needed measurements too. I sent a PM to that guy, he's on Grand Island. Still active on the site so I've got fingers crossed.

I expect to need to replace bearings ($120 on fleabay, should just push the button and resell later if they're all fine) and I expect to have excessive input shaft play which indicates need to re-shim.

I hope to find all gears spinning smoothly on the mainshaft and to have no chipped or pitted teeth. I have no synchro complaints at all, so as long as they all spin smoothly and the mainshaft looks good I'm not going to pull anything off.

What is considered excessive? I checked mine with motor out, no in/out but probably has 1/16" - 1/8" in either direction of float. Didn't find much info on it, aside from post 2 in this thread which was enough for me to stop worrying about it.

If you are talking about side to side to play with the G56 actually REMOVED from the truck, some movement is actually ineveitable, because the front of the shaft is no longer supported by the oem bushing at the center of the dual mass flywheel. In ohter words, with the tranny removed from the truck, the entire input shaft is supported ONLY by the main bearing at the back of the bellhousing, which is actually near the center of the shaft (in terms of length) so when you move the front of the shaft from side to side, it WILL move, though when installed, it no longer can move because it is supported by the bushing at its very front tip. I hope that makes sense.

 None of that is to say that should be ALOT of side play when checking for play with the tranny removed. When my G56 was out of the truck for a clutch upgrade, I could move the front of the shaft almost more then 1/8" in each direction, though NOT in and out. The dealer and 2 different tranny shops told me that this was normal, so I finished the job, re-installed the G56, and have absolutely NO shifting problems or noises.

 Another way to check for bearing wear in the input shaft bearing is to look for discoloration of the bearing or tranny case from overheating, or actaul stress cracks in the case where the bearing sits, or even check to see if the actual bearing is loose or not properly seated in the tranny case. Those ARE signs of too much wear from overheating or overpowering the aluminum case of the G56. Also, IIRC, there should be NO end play (in and out)

 Hope that helps some.

Service manual indicates shimming to zero clearance on the bearings, so no in/out would be the key.

 Found this upon starting work on removal. Good sign to see mixed fresh/old hole in a trans case, right?



Then I got it out and found the bad stuff



Source:



Intermediate disc disintegrating at the pins






Throwout bearing spins smooth but very dry. Fingers not happy with it.



Starter teeth warn pretty badly. Flywheel is fighting coming off the crank so I haven't checked it's teeth carefully yet



Gif, you up for a little aluminum welding project? :(

No need for welding the bell housing back together. Going to see if I can find a fresh front housing. How much I'm willing to spend on that depends on what south bend says about the clutch. Not sure if I qualify for the $600 reman price with that sort of damage.

Countershaft bearing boss is full of cracks. I thought at first they might be casting marks but some show through to the other side.










5th gear has 2 chipped teeth. I guessed that was the case when I bought the truck. Amazing the countershaft looks fine. Countershaft 6th has one tiny burr, no damage on 6th. Bearings all look perfect, nothing cooked nothing rough nothing of note.
