Inspection and Repair
When wear, damage, or any other defects are observed
during the inspection, the part or parts must be repaired or
replaced. Wash all the parts with clean solvent, and
check that old oil, metallic particles, dirt, or foreign
materials are completely removed. Blow the air into oil
holes and grooves to remove foreign materials or residual
detergent.
Chain
Check whether the face that contacts the sprocket is
free from excessive wear or damage. If defects are
observed, replace the part.
If the chain interference mark is found on the inside
w a l l o f t h e t r a n s f e r c o v e r o r t h e c h a i n i s s o s l a c k t h a t a
skipped engagement occurs between the chain and
sprocket, replace the chain.
Sprocket
Check whether the sprocket tooth surface is
excessively worn or damaged, and there is evidence
of burrs, chipping, wear, or damage on the gear
spline. Remove minor flaws or scratches with oil
stone. If excessive wear or damage is observed,
replace the part.
If excessive wear or damage is observed on the
sprocket inside sliding surface, replace the part.
Gear
Check whether the gear tooth surface is excessively
worn or damaged, and there is evidence of burrs,
chipping, wear, or damage on the gear spline.
Remove minor flaws or scratches with oil stone. If
excessive wear or damage is observed, replace the
part.
Thickness of Reduction Hub
Measure the thickness with a micrometer.
If the measurement exceeds the limit, replace the
reduction hub.
Standard : 3.05-3.30 mm (0.120-0.130 in)
Allowable limit : 2.5 mm (0.098 in)

Lock-up Sleeve
Mount the mechanical lock hub, drive sprocket
assembly, and lock-up sleeve to the output shaft.
If the lock-up sleeve does not move smoothly, replace
the sleeve.
NOTE: Apply ATF to the area engaging the gear.
Thickness of Lock-up Sleeve
If the measurement exceeds the limit, replace the
lock-up sleeve.
Standard : 7.16-7.32 mm (0.282-0.288 in)
Allowable limit : 7.9 mm (0.311 in)

Reduction Fork
Check the reduction fork and shaft for wear, distortion,
and scratches. If defects are observed, replace the
parts.
Thickness of Reduction Fork
If the measurement exceeds the limit, replace the
reduction fork.
Standard : 3.41-3.79 mm (0.134-0.149 in)
Allowable limit : 4.4 mm (0.173 in)
261RW026
Lock-up Fork
Check the lock-up fork and shaft for wear, distortion,
and scratches. If defects are observed, replace the
parts.
Thickness Lock-up Fork
If the measurement exceeds the limit, replace the
lock-up fork.
Standard : 6.99-7.09 mm (0.275-0.279 in)
Allowable limit : 6.3 mm (0.248 in)
261RW027
Bearing
Check the profile of the needle, roller, ball, and thrust
bearings. Wash the bearings with clean solvent
completely, and dry with air.
NOTE: If the bearing is rotated excessively, the rollers
may be damaged. So, rotate the bearing slowly with your
hand. Apply grease to the bearing, and check the
smoothness of the bearing while slowly rotating the race
with your hand.
Use a dial indicator to measure the ball bearing play.
Allowable limit : 0.23 mm (0.009 in)
226RW143
Lock-up Fork Spring
Check the lock-up fork spring for distortion, cracking,
and wear. If defects are observed, replace the part.
Free Length of the Lock-up Fork Spring
If the measurement exceeds the limit, replace the
spring.
Standard : 60.96 mm (2.40 in)
Allowable limit : 55.0 mm (2.17 in)

Oil Pump
Remove foreign materials from the strainer. If the
strainer is damaged, replace it.
If the area into which the shaft is inserted is
excessively worn or damaged, replace the pump.
Multi Plate Disk Clutch
If the burned, mirror-surfaced clutch facing, or
scraping is observed on the clutch plates, clutch
housing, armature plate, and insulator washer,
replace the part or parts.
266RW003
Coil Assembly
Check the resistance of the coil with a tester. If
defects are observed, replace the assembly.
