Gates VCP865 Engine Variable Valve Timing (VVT) Sprocket - Exhaust (Left)

OE-Style VVT Sprocket for BMW Exhaust Left Applications

Gates VCP865 is an engine variable valve timing sprocket built to OE specifications for fit, form, and performance. This exhaust-side left cam phaser is designed for BMW engines that rely on precise timing control for smooth operation, fuel economy, power delivery, and lower emissions.

Engineered with aluminum and steel construction, the VCP865 uses a timing chain drive and OE Exact grade dimensions to match the original component layout. It is a direct replacement for select BMW 545i, 645Ci, 745i, 745Li, 550i, 650Ci, 650i, 750i, 750Li, and X5 applications with exhaust (left) VVT service requirements.

Product Details

Gates Engine Variable Valve Timing Sprocket line is built for OE-style replacement service where accurate cam timing matters. Part number VCP865 is manufactured to restore proper variable valve timing operation on the exhaust side of the engine, helping maintain the timing response expected from the original BMW cam phaser design. This part cross-references Dorman OE Solutions 916-502 for the same application.

Compatible With select BMW 550i, 650Ci, 650i, 750i, 750Li, 545i, 645Ci, 745i, 745Li, and X5 models in exhaust (left) positions across the listed model years. VCP865 is also referenced by Standard Ignition VVT534 for related service applications.

What It Helps Address

• Rough idle caused by worn variable valve timing components
• Loss of low-end or midrange engine response
• Check engine lights related to cam timing performance
• Reduced fuel economy from inaccurate valve timing
• Higher emissions from inconsistent exhaust cam control

Installation Notes

• Verify engine code, model year, and exhaust left position before ordering.
• Inspect the timing chain system, guides, and related seals during service.
• Follow factory timing procedures and torque specifications during installation.
• Confirm the sprocket alignment and cam timing after assembly.

Quality Assurance

Gates designs this VVT sprocket to OE specifications and tests it to help restore engine performance, fuel economy, power output, and emissions control. High-quality materials are used to support durability and service life in demanding timing system applications.
