DISASSEMBLY
REASSEMBLY
Grasp ring gear in one hand and tap drive end of spindle with a soft
face hammer; spindle and components will loosen from ring gear.
Gearing should not be disassembled further unless it is neces-
sary to replace a part, as Brinelling of the bearing race may occur,
making replacement necessary.
To further disassemble, remove bearings (33704), rotate snap
ring (40842 or 40843) so the open portion of the ring will allow the
removal of shaft and remove shaft releasing gear. Repeat for re-
moval of opposite shaft and gear.
NOTE: Pack bearings and lubricate gears liberally with 40036-1
grease, or equivalent, during assembly. Gearing assembly
should contain approximately 1/4 oz. of grease.
Assemble snap ring (40842 or 40843) to spindle, aligning open
portion of ring with one shaft hole in spindle. Assemble gear and
shaft to spindle. Rotate snap ring and assemble opposite gear
and shaft. Rotate snap ring to secure both shafts in place. As-
semble bearings (33704) to spindle. Assemble spindle, with com-
ponents, to ring gear, being sure ring gear contains retaining ring
(33708) before replacing spindle and components.
