Cummins 5.9 Flywheel and Flexplate reusing Bolts and Torque specs

[Scott Johnson]

Hey Everyone and especially Tony, 

I am really sorry to hear about your daughters heart issues. I have had a friend have a heart attack recently and it is hitting a little to close to home and to age 51 for me. We have made a donation to the BC Heart and stroke foundation. I hope your daughter is resting and recovering. 

I have rebuilt my TD502’s and am about to reinstall them. I was wondering about a few things:

Engine: (2) 2006 Cummins 5.9QSB 305hp  Transmission: (2)  1985 Twin disc 502

Flywheel bolts : Can I reuse the bolts and flat washers that I have or should I get new ones? The manual says to use engine oil on the threads and torque to 22ftlbs +60 degrees after the 22ftlbs? is this correct?  very afraid of breaking bolts.. Also,  I have heard of people using loctite what are your suggestions? If loctite what colour? Or is oil needed for the correct torque etc..?

Torsion plate? I am installing a Suredrive MOD12, What length, grade of bolt and lock washers? the ones that I have that were on the original thin metal plate seem a bit short for the new plate? What also what about torque specs and and oil vs loctite for these bolts? 

Thanks again for any help or advise. 

 

Scott
