My car is a a 96 2.8 12v FWD Manual and I bought an engine from a 96 2.8 12v Quattro FWD. I just ran into a rather big problem, my clutch/flywheel doesn't fit into the motor I just bought. Does anyone know a fix?

There has to be a fix, swap or shave pilot bearing maybe?

 

Unless you can source an adapter of some sort, you'll have to swap crankshafts due to the drilling differences.

 

On another forum, I'm being told that all I need to do is remove a "torque converter bushing". Have you ever heard of doing this? Swapping crankshafts is a humongous task that I'm not sure I'm capable of doing properly right this moment.

 

I haven't heard of that but I'd definitely follow up on it. I was always told that the actual bolt pattern was different for mounting a flexplate vs a flywheel.

 

I'm pretty sure all you have to do it shave the crank or something of that nature. The pattern in the pic looks the same but measure to confirm then i would measure that part sticking out and shave the auto one down to match.I wonder if the tranny input shaft will fit in tho.

 

Ditto, I've always heard you have to swap the crank. I'd be interested in being proven wrong....

 

Are you and ImTheDevil talking about on the 2.8 or 1.8 motors?

 

both are the same.
its officially official...

heres a quote from the thread

To overcome the crank/pilot bearing issue I did a number of things. First of the input shaft needs a bearing that is 15mm ID and the end of the crank/inner hole in the flywheel is 43mm. I searched around and found a company that sells that size sealed bearing, coincidentally its for an alternator. (43mmOD, 15mmID). The end of the crank sticks out 6mmm, I ground off 4mm from the end which allowed the bearing to sit very nice and snug in that spot. Bolt everything up and its perfect. I couldn't be happier.

 

Nice find jonbonesjones.

 

Agreed - that'll save someone a lot of headache.
