Hi John! Ya I looked it up and it's torqued to 300ft lbs. I do have a few lock up pins and a 3/4" breaker bar. On my 540/M62tu, I used my impact gun to break the bolt loose. I have a 4' bar I slip over my breaker bar for more leverage.
I just want to see Earl's build move forward.

I'm looking forward to your pics on custom tools. Always looking for easier easy to do stuff.
