FEULING PARTS – Manufacturer Ref: 8027

Complete pressure relief valve kit (valve, springs, and piston) designed for the oil bypass systems of large displacement Touring bikes. The valve plunger is precision machined from heat-treated steel to ensure a finish and repeatability suited to the demands of a high-displacement engine. The included spring provides the necessary setting to control the release pressure and oil flow in the bypass channel.

• Function: increases the release pressure of the relief valve compared to the original spring.
• Materials: heat-treated steel plunger, calibrated components for engine use.
• Origin: made in the United States.
• Compatibility: designed to meet the needs of high-displacement Touring models (e.g. CVO 117 on certain listed Harley-Davidson models).
• Workshop advice: bench testing recommended with the cam pressure test tool PART #3801-0071 to check the sealing and proper functioning of the valve after installation.

Ideal for touring and road riders looking to maintain firmer oil regulation on demanding engines — installation and adjustment by a professional recommended to ensure proper setting and engine safety.
