Gates VCP842 Engine Variable Valve Timing (VVT) Sprocket

Gates VCP842 Engine Variable Valve Timing Sprocket

The Gates VCP842 engine variable valve timing sprocket is built to OE specifications for fit, form, and performance. Also referred to as a cam phaser or cam actuator, this timing chain-driven component is designed for Hyundai Elantra, Tucson, Tiburon, and Kia Sportage, Spectra, Spectra5, and Soul applications where precise valve timing is critical.

Key Features

• OE performance VVT sprocket for timing chain applications
• Constructed with aluminum and steel housing materials for durability
• Timing chain drive with 26 teeth and .161 in. tooth thickness
• Overall diameter: 3.65 in.; overall height: 2.07 in.
• Designed to restore engine performance, fuel economy, power delivery, and emissions control
• Direct replacement for Gates VCP842 and cross-reference part numbers including 918-763 and VVT664

Product Details

Gates Engine Variable Valve Timing Sprocket VCP842 is engineered for OE-style operation in engines that rely on variable cam timing to manage performance and efficiency. The sprocket’s 1-row timing chain design, 26-tooth profile, and OE performance rating support accurate cam timing control in the engine valve train. This makes it a practical replacement for worn or malfunctioning cam phasers on vehicles such as the Hyundai Elantra and Kia Spectra when timing response, idle quality, or emissions performance has declined.

Gates’ Engine Variable Valve Timing Sprocket line focuses on OE-spec fitment and durable construction for long service life. The VCP842 is built to match the original component’s dimensions and operating characteristics, helping maintain proper synchronization between the timing chain and camshaft system.

Common Repair Symptoms

• Rough idle or inconsistent engine timing
• Reduced acceleration or loss of low-end power
• Check engine light related to cam timing or VVT operation
• Poor fuel economy caused by timing control issues
• Emissions performance problems tied to worn cam phaser operation

Installation Notes

Verify engine code, timing chain configuration, and OE part match before installation. Because this component works within the valve timing system, correct timing alignment and proper torque procedures are essential during service. Inspect related timing components, chain condition, and oil control passages at the same time to help ensure stable VVT operation after replacement.

Quality Assurance

Gates manufactures this VVT sprocket to OE performance standards using durable materials selected for long-term service in timing chain applications. The VCP842 is tested to help restore engine performance, fuel economy, power output, and emissions control when replacing a worn cam phaser or cam actuator.
