I know that omission on the chart is a mistake and it would seem that 150 in lbs is right. Do what you want and I am sure you will; but I have torqued a lot of crank cases and find that the 150 rating will sometimes strip out the nut or bolt. I like 120 inch pounds and don’t have any problems. This is right between grade five and grade two bolts, as shown in this chart:

Edit: And yes, my torque wrenches get checked.

Long live American manufacturing!
