NOTE
Intermediate gear assembly must be removed and disassembled in
order to adjust the backlash of drive gear.
To adjust the backlash of drive gear (22) with reduction drive pinion gear (29), add and remove
shims (23) and (18) in equal amounts; perform steps 2 through 14.
Remove second reduction gear assembly (30) from intermediate case (27), (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 shaft of second reduction feed
pinion (26).
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 (25).
Remove retaining ring (20), adjusting nut (19), bearing (21), drive gear (22), two woodruff keys (24),
and shims (23) from second reduction drive pinion (25).
To increase backlash of drive gear (22), add shims (23) and remove shims (18) in equal amounts. To
decrease backlash of drive gear (22), remove shims (23) and add shims (18) in equal amounts.
Assemble second reduction gear assembly (30) (subtask d, steps 3,6, and 7 through 10).
Install second reduction gear assembly (30) into intermediate case (27) (subtask e, steps 3
through 6).
Set up dial indicator gage through hole (28) in intermediate case (27) and confirm backlash between
drive gear (22) and reduction drive pinion gear (29) is 0.006-0.016 in. (0.15-0.41 mm).
If the backlash is not correct, repeat steps 1 through 12 above.
If the backlash is correct, perform subtask e, steps 14 and 15.
