Clutch selector valve detent spring for Pettibone 30 12000

The 40TR-7204 spring serves as a mechanical component within the clutch selector valve assembly. It provides the force required to maintain the valve in a specific detent position, ensuring the clutch selection remains secure during operation. This component is designed to prevent accidental movement of the selector valve, which helps maintain consistent transmission engagement.

This part is compatible with the Pettibone 30 12000 model. It is a compression spring with a diameter of 3/8 inch and a length of 1-1/2 inches. These dimensions are specific to the requirements of the clutch selector valve assembly in this transmission unit.

In heavy machinery transmissions, detent springs are used to provide tactile feedback and mechanical locking for selector valves. By holding the valve in the selected position, the spring prevents the gear or clutch engagement from slipping out of place due to vibration or hydraulic pressure fluctuations during machine operation.
