The flywheel bolts were very very hard to get out from the factory. When I ordered new bolts they came with yellow thread locker on them.

Do not remember torque specs sorry.

 

I got it at for the flywheel
Stage 1 45 nm / 33 lbs ft
Stage 2 angle tighten to 65 degree

Pressure plate to flywheel.
25 nm / 18 lbs ft

Don't the flywheel bolts need sealing to stop oil leaking through them from the crank but not 100% on this as always use new bolts which have sealant on.

 

I discovered after installing my flywheel that several threads talked about using thread sealant to prevent an oil leak. Since I didn't do it I was little bit concerned, but I eventually found another thread that say it wasn't necessary when using new bolts (which I did). After 2000 miles no problem so far.
Also you should use a star pattern to tighten the bolts.

 

Thanks for the responses. I can't find a solid answer though: does anyone know if thread locker or a sealant is required on new flywheel bolts for an m66?

 

hey just wanted to clear things up i’m currently swapping my clutch and flywheel on my 05 s40 awd i bought the clutch kit off of elevate and the new bolts for the flywheel came with the thread lock that sets in by heat so i would say yes to thread lock for flywheel as long as it can handle heat but no to any thread lock on the clutch plate those bolts for me came new with no thread lock so i’m assuming no threadlocker on the clutch plate to flywheel bolts they honestly don’t need to be super tight i think someone earlier said about 30 ftlbs
