Ingersoll 131-664 Reverse Valve Detent Spring

Product Description

The INGERSOLL 131-664 is a reverse valve detent spring designed as a replacement internal component for Ingersoll Rand pneumatic power tools. The detent spring maintains positive engagement of the reverse valve mechanism, providing consistent directional control when switching between forward and reverse operation. This small but critical spring ensures the valve stays seated in the selected position under the vibration and torque loads typical of air-driven impact wrenches and ratchets. Installation is performed by licensed mechanics, tool repair technicians, and experienced pneumatic tool service professionals.

This part is used in pneumatic power tool repair and maintenance applications. It is suited for shop environments, fleet service bays, and professional tool repair benches where Ingersoll Rand pneumatic impact tools require internal component servicing. Replacement is typically performed when the reverse valve no longer detents firmly, resulting in unintended directional shifts during operation.

Key Features

• OEM-specification detent spring for positive reverse valve engagement
• Maintains consistent directional lock under vibration and torque loads
• Direct replacement for the original 131-664 internal spring component
• Suited for professional tool repair and rebuild applications

Compatibility

Designed as an OEM-style replacement internal spring component for Ingersoll Rand pneumatic power tools requiring part number 131-664.

Installation Notes

Installation should be performed by a qualified tool repair technician familiar with pneumatic power tool disassembly. Disconnect the tool from the air supply and depressurize the line before beginning any internal service. Small internal springs should be handled with care to avoid loss or deformation during reassembly. Consult the applicable Ingersoll Rand service manual for the specific tool model to ensure correct spring orientation and valve reassembly sequence.
