h. Point the stepped end of the φ14.5 × φ25 ×16 driven
wheel bushing toward the driven wheel, and install it on the
exposed optical axis of the drive shaft. Then screw on the
M14×1 hexagon flange nut on the drive shaft thread.
i.Same as the first step during disassembly, use a special
clamp to clamp the driving wheel drive disc and the driven
wheel clutch cover to prevent them from rotating freely.
j. Tighten the M12×1.25×35 hexagon flange bolts
clockwise with a torque wrench (or wind batch) and a 17#
sleeve. The tightening torque must reach 103±10N.m (10.5±1
kgf.m, 76±7). lbf.ft) range. Then tighten the M14×1
hexagonal flange nut clockwise with a torque wrench (or
wind batch) and a 19# sleeve. The tightening torque must
reach 75±7N.m (7.65±0.7 kgf.m, 55±5 lbf.ft) )scope.
k. At this point, the assembly of the stepless variable
speed sub-assembly is completed.
3. Common fault phenomena/troubleshooting
3.1 The engine can be started, but the rear wheel

3.3 Insufficient high-speed power
a. V-shaped transmission belt is worn or slipped.
b. The clutch cover and the clutch shoe slip.
c. The large spring of the driven wheel fails.
d. Ply ball wear.
3.4 When the engine is at normal idling speed,
the rear wheel rotates rapidly
a. Pulizhu is stuck in return.
b. The small spring of the driven wheel shoe is damaged.
●The vehicle must be parked on a flat and stable ground or a
