3.2 Flywheel pilot bearing question

[wjdunham]

I'm a bit perplexed here, looks like I may not have the correct 3.2 flywheel? I don't see how I get the 3-bolt pilot bearing on the crankshaft and then fit this flywheel, which looks like it might want the press fit bearing. I sourced the used flywheel from a local tech and I just assumed it would be the right one as he helped assemble the engine. What am I missing?

That’s a later 3.2 flywheel with a lightly pressed in pilot bearing. It’s a 240mm flywheel for the G50. The 3-bolt flywheel is a 225mm wheel for the 915

Thanks, that explains it.

Bummer.... they're both 3.2, just not the right 3.2

I bought it from Scott Kinder, he's been great to work with and I'm sure we'll work something out, hopefully he has the correct one. If not, look for a WTB coming soon :-)

Let me know if you need the 915 style after corresponding with Scott (good guy, I agree wholeheartedly) since I have a good used one from my ‘86 I was considering selling on the classifieds. I have a new one on the shelf waiting for my engine to get reassembled by me someday. So the old flywheel will just sit on the shelf for years

Thanks Kevin! Will let you know after I hear back from Scott.

I think I also may need the throwout bearing spacer/shim. I can't find a part number for that as a separate item. I have the circlip part number, but not the shim.

Kevin, I sent you a PM on the flywheel, looks like I will need to find one.

I sent you an email detailing the flywheel I have. Let me check my collection of spare parts to see if I have the spring shim for the release bearing. I know I’ve got an old release bearing on the shelf so I probably do have the shim too

Old thread I know, sorry... so the older 915 bearing had an outside diam of 50mm.
Looking up the part number for a later 3.2, I get 931 102 111 02 and a quick google gets me to
https://www.sp-spareparts.com/en/p/6202-2rsr-c3-fag which shows an ext diam of 35mm. Does that sound about right?

I just picked up a 993 style bearing to use in a 3.2 flywheel on a crankshaft that doesnt have the 3 threaded holes to mount the original style bearing. The 993 style is 999-052-169-00-OEM
and has a 50mm outside diam. Just trying to understand all the different options over the years.
