RKN18532 Meritor governor assembly is a genuine Meritor part from Pro Gear and Transmission. A governor of this type watches reservoir pressure and signals the compressor to start or stop building air, which keeps the brake air system inside its normal operating band. The compressor keeps turning with the engine, so the governor is the control point for how the system is topped up. One on its way out may stop unloading the compressor, unload too early or cycle erratically, and worn internal valves or seals can leak air steadily from the exhaust port. Call us to confirm proper fit for your application.Features
