SHEAVE - CHAIN (Nissan NI973531H)

A worn sheave can cause chain misalignment and premature wear on the chain and other drivetrain components. The sheave, also known as a chain sheave, is a grooved wheel that guides and supports the chain as it moves. During operation, the sheave rotates on a bearing or bushing, and its groove must remain smooth and true to maintain proper chain tracking. If the groove becomes worn or the bearing fails, the chain may jump or bind, leading to erratic movement and potential load instability. This aftermarket replacement part is cataloged under Nissan reference number NI973531H. Verify the serial number or application, then call (562) 693-7748.
