DD15 major overhaul Part 2 how to torque main bearings

This video is part 2, will cover a DD15 major overhaul, as i mentioned in part 1, the engine block has been properly machined by the guys over at Engine Saver Reboring in Chino, California.

I am going to break these videos down into parts, I will explain everything as clear as possible.

In part 1, I went over main bearing installation along with installing a new crankshaft.

This video includes how to torque properly torque the main bearings in a four step process and the tools you will need. You will need a torque wrench, you can use 15/16 socket (12 point).

Here are the steps you will need to follow.

Step 1: 111 ft lbs
Step 2: 184 ft lbs
Step 3: 90 degree torque turn (almost equal to 400 ft lbs)
Step 4: 90 degree torque turn (almost equal to 600 ft lbs)

I recommend, in between each step to rotate the engine, this will verify that the engine can rotate freely and there is no binding or restrictions.
