Key Features

• Engine timing crankshaft sprocket for specific fitment
• Metal construction with gray finish
• 18-tooth design with 1-row chain configuration
• Helical tooth form for quieter timing system operation
• Precision-machined bore for true fit
• Keyway notch included for proper crankshaft indexing
• CAD-designed and manufactured using advanced materials

Detailed Description

Cloyes S925 is a specific-fit timing sprocket used in the engine timing system to maintain accurate crankshaft-to-chain engagement. It is engineered for outer position applications on vehicles such as the 2002-2011 Toyota Camry, 2001-2008 Toyota RAV4, 2005-2010 Scion tC, 2008-2015 Scion xB, 2009-2013 Toyota Matrix, 2010-2012 Lexus HS250h, 2009-2010 Pontiac Vibe, 2002-2008 Toyota Solara, and 2001-2007 Toyota Highlander. The S925 part number is also referenced by OE-style interchange numbers for the same application.

This sprocket is designed for engine rebuilds and timing service where accurate bore size, tooth geometry, and fit are important. Cloyes recommends replacing the chain tensioner, sprocket, and guide components together when servicing the timing chain system to maintain proper chain control and tension.

What This Part Helps Address

• Timing chain noise from worn sprocket teeth
• Incorrect chain engagement caused by sprocket wear
• Crankshaft timing irregularities during engine service
• Fitment issues from a worn or out-of-spec bore
• Timing system service on Toyota, Scion, Lexus, and Pontiac engines

Installation Notes and Tips

Verify engine code, timing system layout, and outer sprocket position before installation. Inspect the timing chain, guides, and tensioner for wear before reassembly, and confirm the keyway notch aligns correctly with the crankshaft. For fitment-specific confirmation, reference the vehicle application details for the S925 before ordering.

Quality Assurance

Cloyes designs and manufactures timing components with CAD-based engineering and advanced materials, then tests parts for function and durability to support reliable engine service. The S925 is built for specific applications and is intended to meet the demands of timing system repair and rebuild work.
