Now this my friends is a torque wrench:

Didn't get a lot done today except for getting the gland nut torqued-down. Some smart friend suggested that I needed to take the engine to a place that works on semi trucks and other large diesels to find the big 3/4" torque wrench for the job. The factory spec is 260 lbs./ft. and the current wisdom from some respected engine builders is to go tighter, as long as you use the right gland nut. The SCAT chrome moly one we're using is supposedly unbreakable, I am not willing to test that claim but I decided that it will be 300+ lbs.

Believe it or not, this is less than at least one builder recommends. I remembered that the only big truck shop I know of happens to be owned by a very respected Porsche guy, Marty Metarian. He is the chief driving instructor for POC, (the racing org. that runs the best school/licensing program in SoCal), and He had helped me out in the past when I rebuilt my Powerstroke diesel. I called him up today.

"Hey Marty, do you have a really large 3/4" torque wrench?"

"Yes."

"How high does it go?"

"I think that one of them goes to 600 lbs./ft."

"That'll do."

So I put the 356 engine in the back of my truck and drove out to Van Nuys to Von's Diesel Repair. Here is the torque wrench:




I kneeled on the opposite side of the motor and he asked me how much torque.

"300."

"Click-click".
