Getting ready to do clutch replace on 66 corsa.

Hi.Going to do clutch replacement on 66 corsa.I did one several years ago on my 65 corsa,the big difference is the 66 is turbo and the 65 just had 4 carbs on a 140 engine.Will I be able to drop rear of engine down and slide it back when I separate trans from engine or would it be better to lower the coplete drivetrain?It's been a while so I would appreciate any suggestions.Thanks steve

It will come out either way and I would suggest removing the entire powerpak also. When I removed mine, engine first, I had the front and rear on jackstands. After lowering the engine I let the frontend back down to the floor then raised the back another 4 - 5" or so to clear the turbo. I was using a Harbor Freight jack. When putting back in the transaxle was put in first then the engine. The tilt adjustments on the jack would not work and I had to use wood blocks to get the angle right. There was no way my jack adjustments were going to work when lifting the entire powerpak. I hope you have a good jack. I am now shopping for another!

Can be done either way. If the transaxil is left in, it will have to be held at the downward angle with some kind of bottle jack and wood blocks. Also have to be careful that the input shaft does not press down on the throwout bearing slide snout and break it. How many of those have we seen?eye rolling smiley

If one has minimal jacks and tools... removing the complete uni-pack as suggested above is probably the better way to go.

If one has a lift, like the EZ Car Lift or other, the project will be much safer and much easier.

It is too easy to damage the input shaft or the clutch if you try to pull just half the power-pack. Drop it all as a unit and then do your work on the floor or a rolling cart (or leave it on the jack). Get help unless you have an overhead crane to support the trans/diff when you separate it from the engine. It's that bending that does the damage. Replace the T/O bearing, pilot bearing and the entire clutch, turn the flywheel. On LM be sure the shop turns the step the exact amount they turn the flat flywheel face. EM are all flat so turn it all.

The entire park will come out on a transmission floor jack. Just put it in the center between the engine and trans/axel so it is balanced. Expect some excitement as you lower it, they can shift. It needs about 24" in the rear to roll it all out so be sure it's jacked up that far. It was a good tip to start with the front jacked up so it can come out level.

Dave, you need to qualify that statement!

On a late you will have to hold the diff down with a block on top of the diff and small bottle jack.

On an early you will have to pull the axles and then hold the diff up after you get to the angle you want.

I recommend removing the entire power pack as well. I've done it a lot lately. angry smiley But hopefully no more for a while.

Just a note to the above, 1964 might be an early, but has the stepped flywheel, as they also have the 164 cubic inch engines!

I suggest dropping the whole drivetrain, as I used to just drop the engine on lates, but the input shaft always hangs up, and now one would want to change the little strut rod bushings anyway... I am speaking of the little rods with the shock absorber style bushings. And most people forget to disconnect the shifter coupler, so they bend that on engine only removals.....

Never miss an opportunity to change a pilot bushing in a Corvair.

Hmmm, I'd check the clearance, and if OK, re-oil the bushing and move on.
I've seen more than one new one not fit after being pressed in place. (fit on end of shaft before, then apparently was compressed to become out of spec when installed)
I've seen improper materials sold (not oiled bronze)
No need to replace without "just cause" is my opinion.

Dan, it may be a personal thing with me. The very first major thing the went wrong with my Vair was the pilot bushing. It was beyond squealing and now shaking the entire car. I was more than 1000 miles from home for work and it was about to drive home. This 1969 and the car was still relatively low miles. I went to the biggest Chevy dealer in Waterloo Iowa and talked to their Vair mechanic. I didn't even finish my sentence and he said pilot bushing. What those last almost forever, how many go in Corvairs. Quick reply "TOO MANY". He told me how to remove it and install the new one with the shaft you are use , not the driver tool. Also get a disk and throw out while your in there, which I did. The disc, throw out and flywheel were all still good, just the stupid cheap little bushing was bad. Several months before that my brother experienced the loose rivets on the flywheel with his 63. Again another Chevy mech, back home, said change the pilot while your in there, there cheap. Fast forward some years later my flywheel started to rattle. I was already starting to hear the squeal again. So it got another new bushing. Well that disc made less than 30K until it couldn't handle the boost. Sure enough the pilot was loose again, this time it got a rebuilt PP, new disc , new throw out, bolted flywheel a new pilot plus balancing. For me, not changing one that has any amount of miles on it is close to Russian Roulette. Even when they are tight, oil light bushings go bad and lube clogs the pours. Over the years I have met other guys with the same issue.

I guess I should add, unlike almost any other car in the world, the Corvair input shaft is also a large and long torsion spring. Who knows what kind of loads hit the shaft and bushing when you flat shift a Turbo or any other hot Vair.

Speaking of pilot bushings and shafts, what's considered too much slop between the two. I just checked both as I'm about to reinstall the diff/trans onto the bell housing. PB diameter is .592 and shaft measures .585. The PB is new.

As long as it doesn't wiggle!

Porous Bronze only... Lube with motor oil... squeeze between Thumb and index finger... until oil comes out pores...
