Hey guys and girls, what is the best place to find the bearing clearances for the main and rod bearings on my OM617? I have some plastigage and want to check them really quick while I have the oil pan off for modification. Also where can I find torque specs for the engine?

Factory service manual, also the Technical Data Book, April 1985 edition?

From the FSM, section 03-318:

Permissible radial runout of of crankshaft journals when mounted on outer journals:
Journals II, V: 0.16 mm
Journals III, IV: 0.25 mm

Is that what you are looking for? Seems like too large of a number to me.

If where you place the plasti guage before torquing is what you are inquiring about, it is between the crank journal and bearing at the low part of the arch (generally laid on bearing). If you are looking for what main and what cylinder that would depend on if you have had the crank ground or just replacing bearings.

Pay special attention to the number one rod bearing clearance in comparison to the others.

I don't suspect anything is amiss with the factory bearings but since I have the oil pan off to modify it, I want to check them to be certain. The crank is still factory and the bearings are factory as well, so just the stock clearance needed for rod journals 1-5 and the main bearing journal clearances.
