Maintenance & Replacement
Inspect sprocket tooth wear and matching at the undercarriage service; reverse or replace when the tooth profile wears hook-shaped or cracking appears at the root, to protect the chain and final drive. Early signs it may need attention: A growing chattering or clunking from the rear undercarriage as sprockets and chain lose phase; Worn, hooked or chipped sprocket teeth that snag the bushing; Badly worn sprockets accelerate final-drive seal and hub wear.

Fit new seals, gaskets or O-rings and torque every fastener to the manual's figure.
