INSPECT.
1.
INSPECT GEARS FOR BURRS, SCORING, AND
WEAR.
a.
Visually inspect drive gear (33), idler gear (34),
drive gear assembly (35), and idler gear
assembly (36) gears, surfaces A, for burrs.
Inspect gear surfaces B for scoring.
b.
Use emery cloth to smooth any burrs on gear
teeth. Clean gears and shafts after polishing.
Refer to cleaning procedure.
c.
Use emery cloth to remove scoring that can be
felt with a fingernail on gears. Clean gears and
shafts after polishing. Refer to cleaning
procedure.
d.
Replace drive and idler gear assemblies (35 and
36) or drive and idler gears (33 and 34) if burrs
or scoring cannot be removed or if gear teeth are
worn to a point.
2.
INSPECT DRIVE SHAFT AND IDLER SHAFT FOR
WEAR.
a.
Use an outside micrometer to measure shaft
diameters C of bearing journals on drive gear
assembly (35) and idler gear assembly (36).
b.
If bearing journal diameter is less than 0.6850 in.
(17, 40 mm) replace gear assembly.
3.
INSPECT DRIVE AND IDLER GEAR WIDTHS FOR
WEAR.
a.
Use an outside micrometer to measure drive
gear (33) and idler gear (34) width. If gear width
is less than 0.441 in. (11, 20 mm), replace drive
gear and idler gears.
b.
Use an outside micrometer to measure drive
gear assembly (35) gear width and idler gear
assembly (36) gear width. If gear width is less
than 0.535 in. (13, 59 mm) replace gear
assembly.
c.
Inspect drive spline of drive gear assembly (35)
for cracks, chips, or wear steps. Replace gear
assembly if drive spline is worn or damaged.
