Is 21207536792 (pilot bearing) the correct part number to use when using a 550i/335is clutch with a 2007 335i 8 bolt original flywheel?

Also which is the correct rear crank seal for the 2007 335i? 11117584398 or 11117587168? Found these two on realoem. I have been told these are two different sizes?

thanks.

Yes, part number is correct: 21207536792. Check the fitment below:

Ref No. 01 in the diagram above:

So, for a 2007 335i, you'd usually go with part number 11117584398 for the rear crank seal. This one's sized at 90x110x12mm and fits the bill for N51, N52, and N54 engines from 2006 up until 2009.

Thank you!
is the 12mm (11117584398) seal which requires a silicone gasket maker? is it the case for 8mm too?

[Gemini562]

For the 12mm seal (part #11117584398), you need silicone gasket maker. No need for it with the 8mm seal (part #11117587168).

Can I use 8mm seal on 2007 n54?
