which flywheel seal???
 

I'm confused... my flywheel seal seems to be leaking - this is the one you can see after removing the flywheel looking at the outside of the engine.

Checking with the parts catalog, I discovered two part # per Perlican parts site:

99911342640 Crankshaft to Flywheel Seal
99911326440 Flywheel Seal

The parts catalog I have (Parts & Technical Reference Catalog by Porshce) and all the diagrams I have seen does not seem to show the Flywheel seal.

So, which one do I need? Why one has the correct part #?

bump.... anyone?

If I look at our host's catalog:

The 99911342640 is for the 78-89 Crank and the 99911326440 is for the 90-98 964/993 crank. I would think that for your 87 930 you would need the 99911342640 which is listed as K-113-426-40 by our host.

Thank you John... I must have been blind :(

No problem, hope it fixes the leak.

Yes, that is correct. Here is a link:
