Good To Know

Q: What does a timing chain tensioner guide do? A: It supports the tensioner and keeps the cam chain at the correct tension so valve timing stays accurate. A worn guide can contribute to chain noise or timing drift.

Q: Should the guide be replaced along with the chain? A: Replacing wear items together during a timing service is common practice. Confirm your model and serial number before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
