5-Z-1833 & 5-Z-2065 Pinion Nut Wrenches

Pictured above are the original Model A Ford script service tools used by dealers to remove and install the large lock nuts which retain the rear axle pinion gear bearings in the rear differential housing race.

The upper wrench is Ford service tool number 5-Z-1833, and is used for the 1928 pinion bearing nuts which were threaded directly onto the drive shaft, not onto the pinion gear. The wrench size opening is 2-1/16 inch for a 2 inch nut.

The lower wrench is Ford service tool number 5-Z-2065, and is used for the larger 1929-32 pinion bearing nuts which were threaded onto the pinion gear itself. The wrench opening size is 2-3/16 for a 2-1/8 inch nut.

These are forged steel tools, many of which were originally cadmium plated.
