Product Details

This timing crankshaft sprocket is used in the engine valve train timing system, where it works with the timing chain, tensioners, and guides to maintain proper cam and crank synchronization. Cloyes recommends replacing the chain tensioner(s), sprocket(s), and guide(s) when servicing the chain, since these parts work together to keep the chain tight and aligned. This part cross-references Nissan OE numbers 13021-7Y000 and 13021-AL51A for the same application. Compatible vehicle coverage includes 2016-2021 Nissan Maxima, 2015-2017 Nissan Murano, and 2019-2020 INFINITI Q50, along with additional Nissan and INFINITI models listed below. The S947 is also used in applications such as 2003-2014 Nissan Murano, 2002-2014 Nissan Altima, and 2003-2009 Nissan 350Z, making it a relevant search match for timing crankshaft sprocket replacement on these platforms.

Common Problems This Part Can Help Address

• Worn or damaged crankshaft sprocket teeth
• Timing chain noise caused by sprocket wear
• Improper chain tracking from a worn bore or keyway area
• Timing system service during engine rebuilds
• Replacement of a timing sprocket during chain, tensioner, or guide service

Installation Notes and Tips

• Verify engine code and timing system configuration before ordering.
• Confirm whether your application uses the outer position or a timing crankshaft sprocket position.
• Inspect the timing chain, tensioner(s), and guide(s) for wear before reassembly.
• Follow factory timing marks and service procedures during installation.
• Check the keyway notch and bore alignment during fitment.
