Milwaukee Jaw Pusher Spring
Model Number: 40-50-8937
The Milwaukee 40-50-8937 is a genuine OEM Jaw Pusher Spring for the Milwaukee M18 Rivet Tool 2660-20. The jaw pusher spring is the return spring in the rivet tool's jaw assembly that pushes the jaws back to their open, ready position after each rivet pull cycle — resetting the jaws to accept the next rivet mandrel for the following rivet setting operation. Correct jaw pusher spring force is essential for consistent, rapid rivet cycling on the 2660-20; a weakened or broken spring causes sluggish jaw reset, incomplete jaw opening, or the tool's inability to accept the next rivet mandrel without manual intervention. A fatigued, broken, or set jaw pusher spring requires replacement to restore fast, reliable rivet tool cycling on the 2660-20.
Using a genuine Milwaukee OEM jaw pusher spring ensures the correct spring rate and free length for the jaw reset mechanism on the M18 Rivet Tool 2660-20. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct spring for your specific unit.
