Detailed Product Description

The Cloyes S1019 crankshaft sprocket is a critical component in the engine timing system, responsible for transferring rotational motion from the crankshaft to the timing chain. Manufactured from high-grade steel, this sprocket offers resistance to wear and maintains precise tooth engagement to ensure consistent valve timing. The sprocket features 23 teeth arranged in a single chain row, which matches the original equipment specifications for compatible Mazda models. Its dimensions, including an inside diameter of 1.04 inches and an outside diameter of 2.13 inches, are designed to fit securely on the crankshaft, supported by a single mounting hole of matching diameter. The absence of a keyway notch and timing marks indicates it is intended for applications where these features are not required or are provided elsewhere in the timing system.

Compatible Vehicles and Applications

• Compatible with Mazda 3 models requiring a 23-tooth crankshaft sprocket
• Suitable for Mazda 6 engines with matching timing chain specifications
• Designed for Mazda CX-7 vehicles needing a single-row chain sprocket

Installation Notes and Tips

When installing the Cloyes S1019 crankshaft sprocket, ensure the engine is properly supported and timing marks on other components are aligned according to the vehicle’s service manual. Verify the sprocket’s mounting hole aligns precisely with the crankshaft to avoid misalignment. Since this sprocket does not include a keyway notch, confirm the correct orientation during installation. Use appropriate torque specifications for mounting bolts to prevent loosening or damage.
