Crankshaft Timing Gear for Nissan Engines ⚙️
Why this part is needed
This precision gear drives the timing chain from the crank to the camshafts and oil pump. It locks valve timing to crank rotation, keeping power, economy, and emissions in check. If you’re refreshing a chain set, rebuilding, or chasing timing noise, this is the core piece to replace ️.
How it works
Mounted on the crank nose via a keyed hub, its hardened teeth mesh with the primary chain ⛓️. Timing marks align with factory references for exact phasing. The gear’s heat-treated profile resists wear, maintaining quiet operation and stable cam/crank correlation.
What happens if it’s worn or broken
Tooth wear or a loose keyway can make the chain jump, causing rough idle, loss of power, rattle on start-up, misfire, and cam/crank sensor codes. In severe cases, valve-to-piston contact can occur, leading to costly engine damage. Metal shavings in oil and erratic timing are red flags .
Pro install tips
Inspect crank key and nose. Replace chain, guides, and tensioner together. Align timing marks, oil the gear, and torque to spec. Always verify with a manual.
