6. Using an appropriate pressing tool, press the Input
Ring gear (recessed side down) into the hub sub-
assembly.
NOTE: Do not use excessive pressing force because it will be
reacted by the main wheel bearings.
7. Install the input carrier sub-assembly into mesh.
The output sun portion of the sub-assembly will
mesh with the output planet gears and the planet
gears mounted on the sub assembly will mesh
with the input ring gear.
8. Install the input sun gear into the area between
the 3 input planet gears.
9. Apply a coating of grease to the cover o’ring and
install it into the o’ring groove of the hub.
NOTE: It may be helpful to stretch the o’ring out prior to
assembly to avoid pinching or shearing when the
cover is assembled.
10. Apply a heavy coating of grease to the cover thrust
washer and place it in the center counter bore of
the cover. The grease will help keep it in the bore
during assembly.
11. Center the cover in the hub bore so that the “JLG”
logo is up. Push it into the bore.
NOTE: Do not hit the cover with a hammer or mallet, shocks
may cause the cover thrust washer to dislodge and
drop into the gear cavity prior to the cover getting
positioned properly. If all the parts are to size and
assembled properly, the cover should not need exces-
sive force to assemble.
12. Install the cover retaining ring into the hub
groove.
