Right you are regarding 400 Nm. I found a link which will help calculate all that. You need to know the actual Tightening Torque of the bolt/nut, how many pounds of Force
You can deliver, and how long your lever (extension on the end of the torque wrench) needs to be.

Using my Tightening Torque of 400 Nm as a target reference, and assuming I can deliver 74 Pounds of Tightening Force (shouldn't bust my b*lls at all), I need a four (4) foot Long Extension. The Length of the extension was what I wanted to know when I went shopping for tools and supplies. If I used the 3 foot handle from my floor jack, the Tightening Force would be 100 Pounds. I'm opting to let the extra 1 foot of extension do the work.

PeachPartsWiki: Replacing Front Crankshaft Seal with "Special Tool"
The flywheel lock is indeed an important part of the job - with the engine removed (yeah I know!) "standard" flywheel locks like BGS 1771 can be used but I've not reached the stage where I've tried to use one of these locks with the engine in the vehicle before.
When I fitted the front seal to my OM617 when it was fitted in the car I ended up using a block up against the front balancer to stop the crank from turning - it wasn't pretty. I guess there's a mega torque requirement for that front crankshaft bolt on the M110 just like there is for the OM617 and M102 (two engine types where I've done this job) - a big effing torque wrench is required. |
