I just put in a new HPOP and the instructions I had from Rubberduck on here said torque was about 160 ft/lbs on the 18 mm bolt that holds on the gear. Well I set my torque wrench for 150 ft/lbs. but it never clicked, instead I noticed I was turning the crank, so would that be considered tight enough ?
I put a breaker bar on the crank bolt and it wedged against the frame, then tightened as much as I could. I didn't use a torque wrench, but you need to get it tighter than just once the motor turns. I used rubberducks torque specs too,
I always tighten it til the engine turns over then give it a good hard pull about 3 times and call it good. i don't wedge the crank or anything. So yes, it needs to be a fuzz tighter.
Whatever you do DON"Ttry to torque to 160, at 120 my bolt snapped the head off
I went to the dealer and talked to a friend who is a mechanic there and we looked it up in the book. The torque for the 18mm bolt is 95 ft/lbs. Luckily we were able to get the old one out without any damage to the new pump.
Dam I wish we could have caught you earlier. But glad you got the bolt out. This happened before, and it got heated for no reason. Yes, it's a writeup, but I did say "I think" and stated I didn't know the real torque spec. And the real specs have been at the end of the thread for a long time. But I'm sorry you broke the bolt, and glad you got it out without problems. I tried to edit the post a long time ago, but could not. Again I'm sorry for any trouble.
