Milwaukee Locking Plier Spring Service Kit (Small)
Model Number: 40-50-0935
The Milwaukee 40-50-0935 Locking Plier Spring Service Kit (Small) is a genuine OEM replacement service kit designed for the smaller plier and clamp sizes in Milwaukee's TORQUE LOCK locking pliers product family, the professional-grade hand-locking pliers, C-clamps, swivel C-clamps, and long-nose pliers built for mechanics, welders, fabricators, ironworkers, and metalworking professionals. The kit bundles the spring components needed to restore correct over-center locking action and reliable release function on compatible Milwaukee locking pliers after the original spring has stretched, fatigued, broken, or lost tension. Milwaukee documents this part in service bulletin 54-49-3130 (September 2016), which is the master service parts bulletin covering the full Milwaukee Torque Lock pliers and clamps lineup.
The 40-50-0935 is the Small variant of the Milwaukee Torque Lock Spring Service Kit lineup, paired with the companion Milwaukee 40-50-0945 Large Spring Service Kit which fits the larger plier and clamp models in the same family (including the 48-22-3410 10 in. Curved Jaw, 48-22-3510 10 in. Straight Jaw, 48-22-3520 18 in. Swivel C-Clamp, 48-22-3521 11 in. Swivel C-Clamp, and 48-22-3531 11 in. C-Clamp). The Small kit is designed for the smaller pliers in the family, generally the 4 in., 5 in., 6 in., and 7 in. plier and clamp sizes. A worn or broken spring on a locking plier compromises the tool's over-center action and release function, which is the entire mechanical principle that makes locking pliers useful, so replacing the spring is one of the most common service repairs on a well-used set of Milwaukee locking tools. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your plier's catalog number against Milwaukee service bulletin 54-49-3130 before ordering to confirm whether your specific tool uses the Small (40-50-0935) or Large (40-50-0945) spring service kit. The companion Milwaukee 06-14-0105 Locking Pliers Adjustable Bolt Service Kit is often needed alongside the spring kit during a full rebuild and is sold separately. Verify by catalog number against Milwaukee's parts bulletin before ordering to confirm correct fitment.
