The Milwaukee 45-88-7165 is a genuine OEM Pulley Hub Washer and structural spacer designed for Milwaukee portable band saws. This precision component seats between the pulley hub and the adjacent mechanism component at the pulley mounting position to provide correct axial spacing and load distribution. It acts as a wear interface and thrust washer engineered to reduce friction and maintain axial tolerances within the pulley assembly, which is critical for proper blade tracking and reducing structural loads on the tool mechanism.
Features
Establishes correct axial clearance between the pulley body and adjacent mechanism components
Provides a hardened bearing surface at the hub contact point to resist wear from rotational loads
Distributes the clamping load of the hub fastener evenly across the pulley mounting face
Maintains axial tolerances within the pulley assembly to ensure proper drive function
Reduces friction between the pulley hub and mounting position components
Prevents belt misalignment by maintaining designed pulley positioning
Prevents excessive pulley side load on bearings during operation
Eliminates pulley wobble caused by worn or missing spacers
Engineered for specific Milwaukee pulley hub geometry to ensure precise bearing surface contact
