Why are you torqueing the flywheel bolts down to?
I've seen people misread the torque specs in the Helms and only torque them down to 17 lbs. Whichs is wrong. I wanna say its like 75 lbs, but I'm not sure (been a while since I've instaleld a flywheel & clutch). Anyways. Make sure you are torqueing it right, and use the lock tite if you need to (I never have for the flywheel atleast.) Also next time you drop the tranny check the threads on the crank (where the flywheels bolts to.) Look for them being worn out or stripped. You may also wanna replace the pilot bearing since a lot of stress is on that when the flywheel isn't on right, it may of gotten messed up.
