# Cam chain

> The cam chain (timing chain) drives the camshaft from the crankshaft and keeps valve timing in sync.

- **Also known as:** Triger zinciri, Kam zinciri, Timing chain, Eksantrik gergisi
- **Turkish term:** Eksantrik zinciri
- **Category:** [Cam Chains & Tensioners](https://motorsikletparcasi.com/en/category/cam-chains-and-tensioners)
- **Page:** https://motorsikletparcasi.com/en/glossary/cam-chain

A **tensioner**, automatic or manually adjusted, keeps the chain taut, and the chain runs on plastic-faced guides. Replacing the chain and tensioner together is recommended.

## Symptoms of a problem

- A rattle from the top of the engine, especially on cold starts and at idle
- The tensioner running out of adjustment
- Power loss from retarded timing

A broken chain or one that jumps a tooth can let the valves hit the piston and cause severe engine damage.
