130706KA0D Nissan TENSIONER ASSY CHAIN, Price: 32.18$, Weight: 0.05kg

Timing Chain Tensioner Assembly for Precise, Quiet Timing ⛓️

This engine timing component keeps constant preload on the chain so the crankshaft and camshafts stay perfectly synchronized. It prevents slack, rattle, and timing drift, which protects power, fuel economy, and emissions. Replacing a tired unit restores smooth starts, quiet operation, and long chain and sprocket life.

How It Works ⚙️

A spring-backed, oil-fed plunger pushes on the chain guide. As oil pressure rises, the plunger extends and a built-in ratchet locks incremental positions to stop rollback. This design maintains tension across temperature swings and high RPM, stabilizing valve timing even during rapid load changes.

If It Fails ?

• Cold-start rattle or buzzing at idle
• Rough idle, misfire, reduced power
• Poor fuel economy, CEL for cam/crank correlation
• Chain jump (no-start) or severe jump causing valve damage
• Accelerated wear of guides, sprockets, and chain
• Oil seep at body/O-ring lowering hydraulic control

Pro Tips for Installation ?

• Pre-prime in clean oil; lock and release per procedure
• Set crank at TDC; align timing marks exactly
• Replace guides/rails and gasket together; torque to spec
• Use correct oil grade; change filter after fitment
• Allow idle fill; verify rattle disappears warm
