Milwaukee Pulley Hub Washer
Model Number: 45-88-7165
The Milwaukee 45-88-7165 is a genuine OEM Pulley Hub Washer for compatible Milwaukee power tools — a precision washer that seats between the pulley hub and the adjacent mechanism component at the pulley mounting position to provide the correct axial spacing, bearing surface, and load distribution geometry for the pulley's rotation and drive function. Washers at pulley hub positions in Milwaukee tools serve multiple purposes — establishing the correct axial clearance between the pulley body and adjacent mechanism components, providing a hardened bearing surface at the hub contact point that resists the wear from the rotational loads of belt-driven operation, and distributing the clamping load of the hub fastener evenly across the pulley mounting face. When the pulley hub washer is worn, deformed, or missing, the axial clearance and load distribution at the pulley position change from the designed specification — potentially causing belt misalignment, excessive pulley side load on the bearing, or pulley wobble during operation.
Using a genuine Milwaukee OEM pulley hub washer ensures the correct inner diameter, outer diameter, and thickness for the specific Milwaukee tool model's pulley hub geometry — a washer with incorrect dimensions changes the pulley's axial positioning and bearing surface contact from the designed specification. Always verify your specific Milwaukee tool's model number and serial number at milwaukeetool.com before ordering pulley hub washer service components.
