Re: Cummins NH220 torque spec main and connecting rod
connecting rods,, tighten to 70-75 ft lbs, then to 140-150.
Loosen them all the way, tighten 20-30, 70-75, then to
140-150. I like to give the rod caps a few taps back and
forth when the torque is at 30 ft lbs just to make sure they
seat nice and clean. ![]()
