130706KA0A Nissan TENSIONER ASSY CHAIN, Price: 28.89$, Weight: 0.15kg

Timing Chain Tensioner for quiet, precise valve timing

This engine part keeps the timing chain tight so cams and crank stay perfectly synced. It stops chain slap, protects guides, and keeps ignition and fuel timing correct. You need it to maintain smooth starts, quiet running, and long engine life—especially under hot oil, long trips, and stop‑start traffic.

How it works ⚙️

A strong spring preloads the plunger, then engine oil pressure adds force. A built‑in ratchet prevents rollback, so tension holds even after shutdown. The shoe/guide surface keeps the chain aligned at every rpm, cutting wear and noise.

Signs it’s failing

• Rattle on cold start (1–3 seconds)
• Check Engine light with cam timing codes
• Rough idle, lazy acceleration, poor MPG
• Metallic debris in oil or chain marks on guides

If you ignore it ❌

Slack chain can jump a tooth, upsetting cam timing. That can bend valves, damage guides, and lead to costly head work or a full engine rebuild.

Pro install tips

• Replace gasket/O‑ring and inspect guides and chain
• Prime the plunger with clean oil; verify free travel
• Clean oil feed passage; use correct oil grade
• Set timing to factory marks and torque to spec
