PLANETARY CARRIER

Measure end play of each pinion gear, and make sure the mea-
surement is within specification shown below. If out of specifica-
tion, replace planetary carrier assembly with new one.

Check working face of each gear, bearing and others for dam-
age, burrs, partial wear, dents and other abnormality. If any is
found, replace planetary carrier assembly with new one.
SUN GEAR

Check if oil passage of sun gear assembly is clogged. For this,
try to pass a 3.6 mm (0.142 in) dia. wire through oil passage as
shown.

Check sliding/contact surface of each gear, bearing and others
for damage, burrs, partial wear, dents, and other abnormality. If
any is found, replace sun gear assembly with new one.
INTERNAL GEAR

Check internal gear teeth for damage, partial wear, dents and
other abnormality. If any is found, replace internal gear with new
one.
SHIFT ROD COMPONENTS

Check working face of shift rod and fork for wear, partial wear,
bending and other abnormality. If any is found, replace with new
one.Pinion gear end play : 0.1 - 0.7 mm (0.004 - 0.028 in)

BEARINGS
1. Make sure bearings roll freely and are free from noise, pitting
and cracks.
SUB-OIL PUMP
1. Check inner and outer circumference, tooth face, and side-face
of inner and outer gears for damage or abnormal wear.
2. Measure side clearance between sub oil pump housing edge
and inner gear/outer gear.
3. Make sure side clearance is within specification. If the measure-
ment is out of specification, replace inner and outer gears
together with new ones as a set.
MAIN OIL PUMP
1. Check inner and outer circumference, tooth face, and side-face
of inner and outer gears for damage or abnormal wear.
2. Measure side clearance between main oil pump housing edge
and inner gear/outer gear.
3. Make sure side clearance is within specification. If the measure-
ment is out of specification, replace inner and outer gears with
new ones as a set.
MAINSHAFT

Check surfaces which contact sun gear, clutch drum, clutch hub,
press flange, clutch piston, each bearing, etc. for damage, peel,
partial wear, dents, bending, or other abnormal damage. If any is
found, replace with new one.

OIL FILTER
1. Apply ATF to the two new O-rings (1), and install them on the oil
filter (2).
NOTE:
Do not reuse O-rings.
2. Apply ATF or petroleum jelly to the new O-ring, and install them
on filter stud.
NOTE:
Do not reuse O-rings.
3. Install filter stud to oil filter.
4. Install oil filter to center case and tighten bolts to specifications.
CAUTION:
Do not knock oil filter with a tool such as a hammer.
SUB OIL PUMP
1. Install outer gear and inner gear in to sub oil pump housing, and
measure side clearance. Refer to TF-133, "
SUB-OIL PUMP" .
2. Align dowel pin hole and mounting bolt hole of sub oil pump
assembly with center case. Install sub oil pump cover then
tighten bolts.
