Flywheel Shim to Measure End Play
I dug these pieces out of a box of parts I bought. ID is 50mm. OD is 60mm. Each is .5mm thick. I am guessing they are VW shims? Can I use these to measure flywheel end play before I buy a new shim?
Our original flywheel and shim were lost in shipping. So unless these work, I’m left to buy a new shim just to check the end play.

Re: Flywheel Shim to Measure End Play
Do they match the diameter of the #1 main bearing? 36 hp vw shims would, later ones will be too large diameter.

Re: Flywheel Shim to Measure End Play
The ID appears to be the same. The OD of the bearing is larger.Martin Benade wrote: ↑Sun Dec 01, 2019 5:02 pm Do they match the diameter of the #1 main bearing? 36 hp vw shims would, later ones will be too large diameter.

Re: Flywheel Shim to Measure End Play
A slight correction of flywheel shims;
All shims--including the thick S90, have 49mm ID x 65mm OD, except the S90 which has its 70mm OD to suit its
larger flanged 2-piece main bearing.

Dick, that is confusing. Could you clarify it?

Re: Flywheel Shim to Measure End Play
It’s been a while, s 90 has both a thick shim and a thin one used together?

Re: Flywheel Shim to Measure End Play
No; just one thick one. I have used a thick AND a thin on a S-90 when the correct thick one was not available. You have to be sure to install the thin one on the flywheel side!Martin Benade wrote: ↑Wed Dec 04, 2019 10:54 am It’s been a while, s 90 has both a thick shim and a thin one used together?

Re: Flywheel Shim to Measure End Play
Thanks. I was confused because Dick gave both diameters for the S 90 shim

He posted that all the shims were the same ID and that the S-90 had a larger OD.Martin Benade wrote: ↑Wed Dec 04, 2019 11:10 am Thanks. I was confused because Dick gave both diameters for the S 90 shim

Re: Flywheel Shim to Measure End Play
When referring to a S-90 specific shim, is its use dictated by the case, crank, flywheel, or bearing?Vic Skirmants wrote: ↑Wed Dec 04, 2019 11:00 am No; just one thick one. I have used a thick AND a thin on a S-90 when the correct thick one was not available. You have to be sure to install the thin one on the flywheel side!
We have a S-90 case, with 356C / 912 crank, 200 mm flywheel, and single-piece #1 main bearing.

Dick:
It might be a bit clearer if you said "All shims have 49mm ID x 65mm OD, except the S90 which has its 70mm OD to suit its
larger flanged 2-piece main bearing. "
Not being critical and I want you to know that I appreciate all of your substantial contributions and enjoy reading your posts!

Dennis; S-90 determined by crankshaft and bearing.
Bruce; the thin bearing has too small an OD to work with the S-90 bearing's larger flange.
