Check the inner circular surface of the driven wheel clutch housing for wear or damage. Use a vernier caliper to
measure the inner diameter of the inner circle. It needs to be replaced when the hole diameter is greater than or equal
to
φ150.5 mm. (Note: The inner ring of the clutch housing has a wear resistant coating, it is not recommended
to polish it, It will increase the wear of the inner ring of the clutch housing, clutch shoes and may also cause
shaking of the ride.)

diameter of the hoof block. If the diameter is less than or equal to φ146 mm, it needs to be replaced.

the clutch shoes is not recommended, it will increase the wear on the inner ring of the clutch housing, the
clutch shoes and may also cause shaking of the ride. )
