Milwaukee Spindle
Model Number: 38-50-0102
The Milwaukee 38-50-0102 is a genuine OEM Spindle for the 2821-20 M18 FUEL SAWZALL Reciprocating Saw. In a reciprocating saw, the spindle is the shaft that carries the blade clamp and moves back and forth to drive the blade through its cutting stroke, converting the motion produced by the gearcase and cam mechanism into the reciprocating action at the blade. It is a precision component that must maintain tight tolerances and ride true in its support bushings and bearings so the blade reciprocates smoothly and squarely. Because the spindle carries the full cutting load and cycles continuously in service, it is subject to wear, and a spindle that is worn, scored, bent, or damaged introduces play, rough or misaligned reciprocation, and reduced cutting performance. Replacing it with the correct genuine Milwaukee OEM spindle restores the proper shaft dimensions and alignment the saw was built around, which an aftermarket part may not match, since a spindle out of tolerance can cause binding, vibration, or accelerated wear on the parts around it.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before placing your order, since running production changes can alter part compatibility within the same catalog number. This spindle is documented at Figure 58 on the 2821-20 M18 FUEL SAWZALL service parts list, where it works together with the cams, sleeve, barrel cam, springs, and bushings of the reciprocating drive. Those companion components are separate parts that wear together with the spindle, so refer to your tool's parts diagram for the correct part numbers and quantities, and inspect the surrounding drive parts when replacing the spindle. Replacing the spindle typically requires disassembly of the gearcase, so follow the correct service procedure and re-grease the mechanism with the Milwaukee-specified grease on reassembly.
