I recently purchased all the goodies for my 2.7 to mate to my 901 box. the ring gear adapter, clutch, and PP. Im having issues though trying to get my flywheel and ring gear mated the the measurements seems to be a tad off on the adapter and I cant put them together. Should I just do a hot cold thing to try and get the metal expanded to where itll fit together or what?

How much are they off?

I would think something isn't right, it shouldn't take heat or cold to make things fit.

PS: Here's my setup, lightened 993 flywheel, ringear adapter and KEP Stage 3 clutch and pressure plate:

I'm confused. Is that ringgear cut down at all? This looks like a complete flywheel.

The ringgear goes on the surface side of the flywheel. The pins are used to locate the pressure plate to the ringear, not to mount the ringear to the flywheel.

Yes, that's more like it. Does the ringear fit flush with the flywheel? Hard to tell from your picture.

No... but it could be because I heated up the gear and cooled the flywheel. Hopefully thats why, if not what would I need to do?

Good question.

It also looks like your ringgear is missing the mounting holes to secure it to the flywheel.
On mine, the pins were removed and the holes reused to countersink bolts to mount it to the flywheel.
The other 6 remaining holes are used to mount the pressure plate to the ringgear.

Where did you get your parts from?

Is the new resurfaced area flat all the way to the flange 360 around ?? I looks like the resurface may not be 100% centered to the flange, leaving a step ??


Andy the ring gear is part of the spacer on this style..

Hmmm. If you look at my ringgear picture, you can see 3 larger holes. That's where the pins were originally. The holes were enlarged (but not all the way through) and 3 countersunk bolts were used in there, then 6 bolts were used to mate the pressure plate to the ringgear (those were longer bolts going all the way into the flywheel).

I'm guessing just using 6 long bolts and leaving the pins would probably work OK for your application.

I know that but if you look at his picture, it looks like the ringear does not evenly touch the flywheel surface.
If it sits on the outer lip, the flywheel needs to be machined to make it sit flush.

The ringear is supposed to fit inside tightly and make full contact with the flywheel surface.

Also note that the inner edge of the ringgear is often chamfered and can make it appear as if it doesn't sit flush when in reality it does.
