Anyone know the tightening torque for flex plate to TQ?

It's an OM617. (1980 300SD). Thanks a lot, I've tried searching under many terms and asked the question in other related threads but no dice so far.

The Haynes manual: Torque converter bolts...42 nm.....31 ft lbs.

My mercedes tech manual for cars of 1983 states:
Hex screws for attaching torque converter to drive plate ...42nm.

Thank you, Charlie. I finally found this spec somewhere online last night, (same answer, 42nm), I know that this tightening torque is pretty important. Too loose and they could unscrew, too tight and could fracture the screws or the flex plate.

I also read that these bolts should have a flat washer plus the wavy/lock washer on each one and maybe some blue Loctite. Mine only have the wavy washers now so I am going to get the flat ones from dealer and re-install them soon w/ Loctite. Might as well do them right, they're easy enough to get to. Thanks again!

Hmmm - Haynes does indeed say 42Nm however the ATSG manual for the 722.1 transmissions says 34Nm...

722.118 Automatic transmission rebuild (Monster DIY)

I'm not trying to be a pain - I wonder what the FSM says. I've got a German one on CD - if I can ever get my act together and put Windows on a blinking machine somewhere I'll be able to check it out... as Hinderows is a requirement for the anti-theft software...

I'm not sure if I should trust ATSG or Haynes on this one. The 1983 spec could be referring to the 722.3 you see...

Good to know Charlie - thanks - so ATSG might not be the reliable one then...
