c. Check whether the Puli beads are worn out or round,
and need to be replaced if they are out of round and
deformed. Use a vernier caliper or an outside micrometer to
measure the diameter of the outer cylindrical surface of the
Puli beads. It needs to be replaced when the diameter is less
than or equal to φ24.5mm (1 in).
d. Check whether the V-shaped transmission belt is
damaged such as cracks, broken wires, or missing teeth. If it
does, it needs to be replaced. Use a vernier caliper to detect
the widest part of the V-shaped drive belt. It needs to be
replaced when the width is ≤25.4mm (1 in).
e. Check whether the inner circular surface of the clutch
cover of the driven wheel is worn or damaged. Use a vernier
caliper to measure the inner diameter of the inner circle. It
needs to be replaced when the hole diameter is ≥φ151mm
(5.945 in).
f. Check whether the driven wheel clutch shoe is worn or
damaged. Use a vernier caliper to measure the hole diameter
of the hoof block. If the diameter is less than or equal to
φ146mm (5.748 in), it needs to be replaced.
g. Check whether the 61903 ball bearings and 28×18
needle roller bearings press-fitted in the fixed shaft of the
driven wheel are worn or damaged. If they are worn, loose
and loose frames, they need to be replaced.
Note that the bearings don’t need to be geased to prevent
the grease from slipping on the belt.
2.4 Assembly
Caution:
●Before assembling, it is necessary to conduct a
comprehensive inspection of all the parts of the
disassembled continuously variable clutch sub-assembly, and
replace the parts that reach the limit of use.
●Use compressed air to completely clean the dust
accumulated in the left crankcase belt chamber before
assembling.
●Before assembling, it must be ensured that there is no oil
stain on the driving wheel, V-belt, and driven wheel to avoid
slipping failure after assembling.
a. First install the φ23.2 × φ40 ×3.25 washer on the
crankshaft and assemble it in place.
b. Then check whether the 8 Puli beads are completely
placed in the Puli groove of the driving wheel sliding disk
(Figure 1 below), and then assemble the slope plate with the
four guide blocks corresponding to the position of the driving
wheel sliding disk guide post on the driving wheel. The wheel
slides on the disc (picture 3 below).
Caution: The covered end of the inner hole of the Puli
bead points to the counterclockwise rotation direction.
Otherwise, it is easy to cause the failure of the embedded
steel sleeve of Pulizhu to fall off when the engine is
running! ! !
