Author Topic: How to know flywheel type (Read 2824 times)

Seems that time for clutch service will come soon on my E30 89' m42.
To order right parts its good to know which flywheel do I have - single or dual mass.
Does anybody know - is it present any change to know it without disassembling?
Thanks.

As I know clutch is the same for both...

Hmm, maybe difference is minor, I still have not change it on this engine.
But ETK shows:
Kit for single mass: 21 21 1 223 570
Kit for dual mass: 21 21 1 223 571

Is it pressure plate or clutch assy?

If you have air conditioning I would think you have the dual mass flywheel.

- No A/C. But I was making a SWAP from M10 and not sure that my current engine at "original" car was with or without.
