Milwaukee 2nd Stage Gear
Model Number: 32-44-5375
The Milwaukee 32-44-5375 is a genuine OEM 2nd Stage Gear for use in the gearcase of a compatible Milwaukee tool. In a multi-stage gear train, the tool's motor spins fast but with relatively low torque, and the gear train steps that rotation down through successive stages to a slower, much higher-torque output that drives the tool. The 2nd stage gear is one of those reduction gears: it meshes with the gears above and below it in the train to transmit and further reduce the rotation, multiplying torque as it passes the drive toward the output spindle. On some tools this stage also carries a rotating clutch that protects the drivetrain by slipping under an overload. Because it carries the full working load of the drivetrain and its teeth mesh continuously under torque, the 2nd stage gear is subject to wear: worn, chipped, or stripped gear teeth cause noise, vibration, lost power, or a drivetrain that binds or fails to transmit power. Replacing it with the correct genuine Milwaukee OEM gear restores smooth, quiet, full-power operation of the gear train.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, and because a gear is matched to the exact gear train it runs in, always verify your tool's serial number against the official Milwaukee service parts diagram before ordering to confirm this is the correct 2nd stage gear for your tool, since the tooth count, module, and bore must match the mating gears exactly. Do not order by appearance, since gears that look similar can differ in tooth profile and dimensions, and the diagram is what confirms the correct part. Because replacing a stage gear involves opening the gearcase, the other stage gears, the shafts and bearings they ride on, and the clutch components that work with this gear are separate parts, so refer to your tool's parts diagram for the correct companion part numbers, and inspect the mating gears, bearings, and shafts when servicing since a worn gear often accompanies wear elsewhere in the train. Follow the correct service procedure and re-grease the gearcase with the Milwaukee-specified grease on reassembly.
