Regreased ? The amount of grease required is merely enough to just SMEAR the faces of the sprag. Any more than that is enough to stop the pivoting of the sprag inserts, that in turn means that the unit will slip , and not drive. Any further problems send the unit to me and I will check out.
Designed drives with sprag clutches for a long time, not overgreased and not slipping - the motor stalls. The drive is short of power, and the more I do the less I think it's the drive, and the more it seems to be the engine demand that's changed.
