I am finally reassembling my 914-6 after the Dr Evil transaxle rebuild clinic. I do not recall seeing an O-ring between the flywheel and crankshaft when I dissembled.
What size is the O-ring? It appears to go in the inner grove as shown in the pic. Appears to be 27mm OD, 22mm ID, 2.5mm cross section. Or should I say my kit has one about that size that fits. Does anyone have the exact size? |

Do you mean a dowel pin? If I recall correctly, no dowel pin. Only 6 brand new flywheel bolts.

Ha ha! I thought his finger was pointing at a flywheel bolt hole!

Pilot Bearing Thanks! I found my bushing and new pilot bearing. (This is what happens with long delays between take apart and put together, LOL.) Not obvious where the O-ring would go? I assume between the flywheel and crankshaft? The outer grove is barely a grove, and is way more than the 58mm mentioned for OD. I believe this is the original -6 flywheel. (Yes has been machined / resurfaced.) |

There's no o-ring in there at all. Do you mean the rear crankshft seal?

Thanks for all the replies. So no O-Ring on a 914-6. (Only on a -4.)
Is there a felt washer? If so, I assume it goes between the pilot bearing and the 6-hole washer / plate, correct? Thanks! |

Not that I know of but my flywheel isn't a 914/6 one but 911 2.2T,no "o" ring in mine. The felt washer is built into the pilot bearing. What concerns me is the machined surface that mates to the flywheel appears to have been sandblasted ?? is that just me or just the photo?. Cheers. |

Looks like the felt washer is #6 in the "bush complete" listed as 901 102 025 01
Will check what's in mine when I remove the old bearing from the bushing, likely guess at size to replace it. |
