NOTE
Intermediate gear assembly must be removed and disassembled in
order to adjust feed gear and hub backlash.
To adjust the backlash of gear and hub (17) with reduction drive
pinion gear (22), add and remove
shims (16) and (18) in equal amounts; perform steps 2 through 13.
Remove second reduction gear assembly (23) from intermediate case (24) (subtask a, steps 3
through 7).
Remove four screws (1), lockwashers (2), cap cover (3), and gasket (4) from cap (5).
Remove six screws
(15), lockwashers (14), and cap (5) from bearing retainer (13).
Remove cotter pin (7), nut (6), bearing (8), and shims (9) from second reduction feed pinion (20).
Remove
retaining ring (10), adjusting nut (11), bearing (12), retainer (13), and shims (16) from gear
and hub (17).
Remove gear and hub (17) and shims (18) from second reduction drive pinion (19).
To increase gear and hub (17) backlash, add shims (18) and remove shims (16) in equal amounts. To
decrease backlash of gear and hub (17), remove shims (18) and add shims (16) in equal amounts.
Assemble second reduction gear assembly (23) (subtask d,
steps
6
through
10).
Install second reduction gear assembly (23) into intermediate case (24) (subtask e, steps 4
through 6).
Set up dial indicator gage through hole (21)
in intermediate case
(24).
Confirm that backlash
between gear and hub (17) and reduction drive pinion gear (22) is 0.006-0.016 in. (O. 15-0.41 mm).
If
the backlash is not correct, repeat steps 1 through 11 above.
If the backlash
is correct,
go to subtask
e, steps 14 and 15.
