Sadly I am another Crown up-grader, the casting of a corvair saginaw is rather thin where the Crown adapter attaches.

I have broken Phils former car a few times, one failure, the first discovered and only fail not my fault, a loose press fit on the pinion shaft bearing of the fancy input shaft that allowed the pinion set shim to burn, killing the setup, wearing out the 3.08 ring gear teeth. (Got the car this way, one owner between Phil and I, broke the worn thin ring gear tooth off within 4 miles of delivery) I rebuilt but had another issue within a few thousand hard miles (it has been 10 yrs, forgot what broke)

Currently the car has a Wills big car saginaw and a stock 65 3:55 open diff that has never been opened, it seems to be holding the power but I sorely miss the posi. No plans to C5 it, love the car configured the way it is!

Currently out road racing (non corvair) a bit preoccupied and having a blast.

Lately, the corvair only comes out on special occasion. Have NEW richmond 3.08 gear set, as well as, most everything to rebuild Phil's fancy diff. Anyone have a fix for the loose bearing fit OR a really nice OEM or fancy replacement?

If he still has it, the crown trans and shifter are still around, in possession of Chuck, not really a internet guy but a true a Corvair addict, ultravan and Kelmark owner, a member of South Fl. Corvairs.


Fancy= CIDCO? Phil, can you fill me in?

Ed...the owner in between us broke the ring gear the first week he owned Vairy.

So anything we (my Dad and I) did to build that trans and diff was null and void.

Very good to hear that you and Vairy V8 are still rocking and rolling out there.

Any insight/fix on the loose bearing issue? Is this a thing on other cars?

Maybe a place that rebuilds hydraulic cylinders could repair it. They have to rebuild bad shafts.

I will shelve all my Crown parts when and after I go to the C-5-6 diff. I can't drive too aggressively with that tiny ring gear. Broke on too many on track days and it sucks to get only a dozen or so laps in and POW! Just when you are getting a good feel for a track getting faster and faster.

I need a more bulletproof setup with many more gear options A Jerico will solve that issue. CV8 will never again see the street track only driven as hard and SMOOTHLY as my talent level permits. Way too much fun to thrash this car!

Crown V-8 mid engine conversions were made to GO FAST IMO. To bad they don't hold up well on the track.

Typically it is done by completely remaking the part, or building up the surface with hard plating.

On a Crown, once you figure out which pinion shim you need, you put the shim behind the rear bearing race, cant spin there! A miss match of rubber mounts at the adapter plate and solid in the rear causes twist and breaks the front of the trans. A simple solid mount set up with some bracing solves that issue. Not Dial indicating the Bellhousing causes all kinds of issues. Its all in the set up. Mike

I'm solid at three point, runout of bell is 7 tho still have issues. last failure was a Lakewood universal joint at speed! Got my attention. Broke all kinds of sh1t! Cambered to a point where it cut a brand new Proxis r888 launched the car bent the radius rod and the lower traverse mount bracket (Crown piece) cracked the diff housing, what a BAD day just as it was getting fun.
