Halp! Refitting transmission nightmare

mike saunders · 02-20-2012, 05:16 PM

Anyone have any quick tips on how to make sure the tranny input shaft mates properly with the teeth in the flywheel?

PoisonBeef · 02-20-2012, 05:54 PM

Um, it just has slipped on most times, without too much trouble.

mike saunders · 02-20-2012, 06:03 PM

I replaced the flywheel so I'm guessing I don't have the splines aligned...

Went through this today.

You keep wiggling and pushing the trans onto the engine.

The other guy turns the crank and intermediate shaft ever so slowly (lots of teeth)

Usually about 3 minutes in, right before you want to take a break and check again for what's holding you up, it pops on. Pop! just like that.

Always a pain!

This drama has just been noted.

I'm dropping my box in a couple of weeks.

Be prepared everyone for many threads of me fucking shit up

I apologize in advance

Say what? The Teeth on the flywheel connect with the bendix of the starter. The input shaft connects the clutch, Just turn the engine over while your installing the trans.

May sound dumb but I don't really know you. Did you use the clutch alignment tool to center the clutch. If so then like they said have somebody turn the engine over slowly. If you don't have a socket that fits the crank pull you could use a pry bar on the flywheel teeth if needed

This is what I ended up having to do. It sucked. I was alone under the car with the trans on my chest turning the flywheel ever so slowly to get it all to mesh up.

mike d · 02-21-2012, 04:56 AM

i usally dont turn the motor over to aling it, i just shake the CV input to turn the gearbox side..

Did you use the alingment tool? i have an old input spline that i cut off a blown tranny at the shop that works magic.

also, how are you suporting the trans? some people say to use a jack, but ive never had luck with it,, i usally tie the trans up by a motor hoist, and swing it in,, this seams to work much better.

BuHuSPG · 02-21-2012, 05:27 AM

I would 2nd (3rd) the request as to whether you used the alignment tool. Pretty hard to get it in without, so I bet thats the issue.

If you did, then it's a matter of putting it in level (hard to do, usually requires a little fight) and turning the splines of the FW.

VI009DZ · 02-21-2012, 05:51 AM

funk that...........

If you loosened the pressure plate and let the clutch disc move around, put the disc back on, tighten up the pressure plate bolts but only enough so that you can still move the disc around. Center the disc, on the pressure plate (use your fingers to "feel" the edge of the disc in relation to the edge of the pressure plate, around the whole circumference), and adjust as necessary. When you have it centered, lock it down the rest of the way with the pressure plate bolts.

Done no less than 10 this way; never used a tool.

mike saunders · 02-21-2012, 06:07 AM

The clutch splines are probably misaligned. I replaced clutch and flywheel and probably need to loosen the pressure plate to use the tool, which came with the clutch.

I was in the shower about an hour ago and realized what a dumb douche I was being for not understanding that the frigging clutch was probably the issue...then I read the replies here and got confirmation...

I used a wagon hitch pin for my alignment tool. Worked great.

BuHuSPG · 02-21-2012, 06:58 AM

Yes, agreed with the above. There is nothing special about the "actual" tool.

I too have used my finger, a piece of a broomstick, and a deep socket before.

Point is: you have to center it somehow.

mike9000aero · 02-21-2012, 07:02 AM

Yeah you don't need the tool. I can't Denver what socket I used but there's a socket that works perfect

DeLorean · 02-21-2012, 07:08 AM

First thing, you should be sure to use a clutch alignment tool. Even with the tool, there is some play, be sure the disc is centered.

Trans should be in gear, and as you engage the clutch disc to the splines if it does not want to go in rotate the input shaft a bit by turning the drive axle output shaft and it should drop in place.

This. I had to turn the output shaft a little bit to get mine to mate up last time.

I use a center punch and a socket to line up mine. Worked perfect on the Saab and Subie.
