torque spec 1971 280SE flywheel bolts - PeachParts Mercedes-Benz Forum

I am involved in a project- 1971 280SE, changing from an automatic to a manual. I have all the parts from the donor W108, and new flywheel bolts. Anyone know the torque specs for the bolts? Should I use Locktite? Also, there was a ring between the auto flywheel and the bolts, should I use it on the manual FW? I looked online, and could not find any specs anywhere. I searched here as well, but nothing specific found. Thanks in advance, Rich

1) Initial tightening: 30lb/ft. Then 90-100 degrees of rotation.
2) No Loctite required, but Blue if you are nervous.
3) Do not use shim washer/ring; the bolt heads could interfere with clutch disc.
