Hi

I´m going to service the clutch, and was wondering to check the IMS/RMS issues at the same time.

Which IMS version (the bearing) do I have.

The engine number is M97/01 68702641 (the 5th digit can be "G" as well, difficult to say). So, when is the engine built?

Thanks

Kare

The best thing to do is look at it --

From Charles at LNEngineering a Deep inset flange is a single row, a shallower flange is a dual row.

This is supposed to be a single row -- I have not confirmed will do so soon

2004 996 3.6L

This is supposed to be a dual row -- I have not confirmed this one yet either.

1999 996 3.4L

This is what happens when it fails.

1999 2.5L 986

I was searching with different keywords information how to decode the engine number. As the model is M97/01, followed with 687.....I suppose the model year is from 2007??? Am I right? I don´t know it exactaly as I boufgt the engine separately...

Yes, serial numbers starting with 697 should be model year 2007.
