Six. Inspection of parts and limit values for use
Note: Every 20,000 kilometers, the CVT clutch sub-assembly needs to be inspected, maintained or
repaired ! ! !
1. Check items and usage limits of the driving wheel
①
Use a knife-edge ruler to align the tapered working surface of the driving wheel (Main fixed disc and sliding disc) in
parallel, and then use a feeler gauge to check the amount of wear. It needs to be replaced when the gap is greater
than or equal to 0.5mm. Use a vernier caliper or inner diameter micrometer to measure the inner lining aperture of the
driving wheel sliding disc. The aperture ≥35.15mm needs to be replaced.
②
Measure the outer diameter of the distance cylinder with a vernier caliper or an outer micrometer. It needs to be
replaced when the outer diameter is less than or equal to φ34.9 mm.
③
Check whether the centrifugal roller is worn and out of roundness, and need to be replaced if they are out of round
and deformed. Measuring the diameter of the outer cylindrical surface of the centrifugal roller with a vernier caliper or
an external micrometer. If the diameter is less than or equal to
φ24.5 mm, it needs to be replaced.
④
Check whether the V-shaped transmission belt is damaged such as cracks, broken wires, or tooth loss. If it occurs,
it needs to be replaced. Press the measurement method shownin the figure below to measure the widest part of the V-
shaped drive belt (dimension a in the figure). It needs to be replaced when the
width is ≤25.5mm.
