[QUOTE=sawdustdad;260619]On the locking collar issue, I believe the manual is correct (imagine that). Lock the collar counterclockwise standing in front of the engine facing the PTO. This is necessary because resistance to the engine's rotation (caused by a load on the belt) creates a clockwise torque, effectively tightening the collar.
I thought of that, but I figured that if the bearing is freely rolling, then there won't be any rotational connection from the pulley to the bearing collar at all. The bearing is simply there to allow free wheeling while disengaged. When the PTO is engaged the bearing really only helps keep the pulley hub on center. There is no transfer of torque through the bearing when functioning properly. When the bearing fails through seizure, then there are other symptoms that are seen before things get dangerous.
Wouldn't you agree?
