NISSAN 13021-VC200 Crankshaft Timing Sprocket

The genuine NISSAN 13021-VC200 timing chain sprocket (GEAR CRANK) is an essential component of the engine valve timing mechanism. Mounted directly on the crankshaft, it transmits torque to the timing chain, ensuring precise synchronization between the crankshaft and camshafts during valve opening and closing cycles.

Technical Specifications and Operation:

• Part Type: Crankshaft Timing Sprocket (Crankshaft Timing Sprocket / Gear Crank)
• Manufacturer Part Number: 13021-VC200
• Manufacturer: NISSAN (Genuine OEM part)
• Installation Position: Engine block / crankshaft nose, timing drive
• Material: Precision-machined, surface-treated, hardened carbon steel for maximum wear resistance and load capacity
• Function: Direct mechanical drive of the timing chain and maintaining precise engine timing phase

Wear and Failure Symptoms:

Wear on the timing chain sprocket typically presents as tooth profile wear, shark-finning, or hooking, most commonly caused by normal chain elongation or inadequate lubrication. A worn sprocket can cause noisy operation (chain rattling), timing drift, and in extreme cases, chain skipping or breakage, which can result in catastrophic engine damage. Replacing the sprocket is strongly recommended during a complete timing system overhaul.
