Front variator bushing for Suzuki AD scooters (the size in the name is 22*39). It is the guide on which the movable half of the pulley slides.
Replace it if the pulley has play, is misaligned, or knocking appears. A worn bushing impairs the operation of the variator and speeds up belt wear.
- Make sure there is no oil on the parts and the belt.
- Replace worn variator parts as a set, not one by one.
- Also inspect the neighboring parts of the assembly: they often wear out together.
