Any tips on fitting trans axle

[crossram]

I have a 6 speed G97 transaxle Im fitting to the SBC adapter plate. I have tried numerous times to get it to fit with no results.

I made sure I had the clutch facing the right direction , added the grease to the transaxle shaft.

I pre fit the Sachs clutch on the spline of the trans axle... it fit

I mounted clutch with the alignment tool

it lines up nicely with the two fixed studs I can feel the tip of the transaxle spine touch the clutch but it won't go in.

I backed off and gave the flywheel a slight turn, tried again no luck


We then took the the clutch off and tried fitting the case alone to the adapter plate and it fit up nicely.

Clutch pre fit again , mounted again, but it just won't go on


Any tips or suggestions?

Another angle

[crossram]

Yes

When we pre fit the case I took angle measurements on both the engine and the trans axle while the unit was together.

Thinking that if I duplicate those angles it might make it easier to slide in.


still no luck

I ran a camera into the trans axle, it looks lined up, do you think maybe the clutch fork is preventing it?

But at some point you have to tighten down the bolts and try it the way I am now, we did prefit the transaxle to the adapter plate and it lined up perfectly.

Do they all go this way?

[crossram]

If you look at the picture I took of the spline trying to align with the clutch I don't think the clutch tube is involved

When you guys installed yours did it take two people to push it in? or were you able to do it by yourself?

I have the box on a sling at the same angle as the engine, I know they are at the same angle because I took measurements of both when I installed the transaxle without the clutch.

Do you have a G50?

[crossram]

It's very frustrating, I might just pull the whole engine out and pre fit it. but that means I will have to build a special stand for the engine that doesn't use the threaded holes on the end of the engine case.

Thanks I did and I also used a bar and carefully rotated the flywheel

[crossram]

I loosened up the pressure plate bolts to a point were the clutch will move about a 1/16 of a inching any direction. I slid the transaxle back in and pop! it slid in!


Thanks for that suggestion


I now know it fits

So any suggestions on how to remove it without changing the position, allowing me to tighten all the pressure plate bolts up ?

[crossram]

I tightened a few bolts on the pressure plate, then retested, removed transaxle. Tightened everything to spec and it popped in !


Thanks for your help

Thanks

It's a crossram manifold on a 327 Corvette engine using a Holley EFI CPU, Scintilla magneto is actually a MSD unit, because I had a width problem on the manifold. Real Magneto's and EFI don't get along well.

My build is retro and shares no body parts with the Ultima.

Dave Ehrlich of Autotrend USA built the unit. If you want a custom EFI unit he is one of the best technicians in the business with over twenty years experience in EFI.
