Milwaukee Tool Free Spring
Model Number: 40-50-0083
The Milwaukee 40-50-0083 is a genuine OEM Tool Free Spring, a precision-dimensioned spring that provides the return and holding force for a tool-free mechanism on the tool it serves. Tool-free features, such as tool-free blade clamps, tool-free shoes and guards, and other quick-change mechanisms, let the operator change accessories or adjust the tool by hand without a wrench or key, and they depend on a calibrated spring to return the mechanism to its home position and to hold it securely in place. This spring supplies that force. As with any working spring, its rate, free length, and wire diameter are all critical to correct function, so an incorrect spring can cause the tool-free mechanism to fail to hold, fail to release, or feel wrong even if it physically fits the space. Because the spring is actuated every time the tool-free feature is used, it is subject to fatigue and can weaken, set, or break over time, at which point the mechanism no longer holds or returns as designed. Replacing it with the correct genuine Milwaukee OEM spring restores the proper spring-loaded function the tool-free mechanism was built around.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, and because springs are specific to the exact mechanism they serve, always verify your tool's serial number against the official Milwaukee service parts diagram before ordering to confirm this is the correct spring for your tool and its tool-free mechanism. Do not order by appearance, since springs that look similar can differ in rate, free length, and wire diameter, and the diagram is what identifies the correct part at each position. Order this spring by its exact catalog number, and refer to your tool's parts diagram for the surrounding tool-free mechanism components, which are separate parts that should be inspected when the spring is replaced since they work together.
