face hammer; spindle and components will loosen from ring gear.
To assemble gears and bearings to spindle, reverse the proce-
dure of disassembly. NOTE: After assembling gears and shafts to

sary to replace a part, as Brinelling of the bearing races may oc-
cur, making replacement necessary.

move shaft, releasing gear. Repeat for removal of opposite shaft
