●Chain adjuster assembly bearing maintenance

It is recommended to inspect, maintain and clean the bearings every 6,000 km. After removing the chain

adjuster assembly according to the previous steps, clean the bearings inside with gasoline or diesel. Carefully

check the bearings for damage, smooth rotation, and noise. After confirming the pass, wipe it with a clean,

lint-free cloth and re-apply the grease evenly on the bearing.

the oil seal is damaged; the bearing needs to be pressed into place.
