ABSTRACT:
An improved gear wrench is disclosed having an indexing clutch assembly operably coupling an output shaft with a gear assembly. The indexing clutch assembly includes a rotor, a freewheeling mechanism rotatably coupling the rotor to a drive shaft, a stator, and an indexing mechanism operably coupling the stator to the drive shaft. The freewheeling mechanism provides driving engagement of the rotor and the drive shaft in a first direction and freewheeling or relative rotation therebetween in a second direction. The indexing mechanism appropriately positions the drive shaft in a predetermined indexing position when rotated in a second direction and prevents further rotation thereat. The present invention further includes an angular adjustment mechanism for adjusting the indexing position of the drive shaft relative to the indexing clutch housing.
