Front Gearcase Assembly
5.
Install ring gear assembly, steel spacer, brass
spacer and side cover. Make sure lock bolt on
holding fixture is backed out of the way. Rotate
pinion shaft while slowly turning side cover inward
until gears mesh. As gear backlash is reduced to
zero, the shaft will begin to bind. At this point back
off 1/4 turn.
6.
Tighten locking bolt on holding fixture against
drive shaft until shaft is held securely and will not
rotate. This will also force ring gear against cover
to maximize backlash.
7.
Install backlash tool on pinion shaft as shown.
Position dial indicator 1.875" (47.63mm) from
center line of shaft which is indicated by first mark
on tool.
Be sure dial indicator shaft is
perpendicular to surface of tool. If dial indicator is
placed any other distance or angle, backlash
measurement will be inaccurate.
8.
Rotate pinion shaft back and forth to read total dial
indicator movement. Backlash must be between
.004"-.007" total movement.
NOTE:When changing backlash:
•
To reduce backlash loosen lock bolt securing
output shaft and rotate side cover clockwise
as viewed from cover side.
•
To increase backlash loosen lock bolt secur-
ing output shaft and rotate side cover counter-
clockwise as viewed from cover side.
•
Be sure to tighten the lock bolt against shaft
when rechecking backlash.
•
When backlash is properly set, rotate output
shaft 180
0
and verify proper backlash at this
paint on the ring gear.
