Gearcase Assembly
The 'loose head' symptom is caused by the loss of fastener preload in the screws connecting the ratchet head to the tool's yoke. Over time, the high-torque vibrations of the planetary gear set back the screws out, leading to physical separation between the metal head and the housing. Replacing the gearcase assembly or the fastener set with pre-applied thread-locking compound restores the structural clamp load required to maintain head alignment.
