Milwaukee Bushing for M12 FUEL High Speed Ratchets
Model Number: 42-40-0017
The Milwaukee 42-40-0017 is a genuine OEM QPQ Bushing for the Milwaukee M12 FUEL High Speed Ratchet family — fitting models 2566-20, 2567-20, 2568-20, and 2569-20. The QPQ designation refers to the Quench-Polish-Quench surface treatment applied to the bushing — a hardening and polishing process that improves wear resistance and surface hardness while reducing friction at the bushing-to-shaft interface. Bushings are cylindrical bearing-style components that support a rotating or sliding shaft, pin, or spindle within the ratchet head assembly — maintaining precise alignment and reducing metal-to-metal friction and wear during the high-cycle ratcheting motion. A worn, scored, or damaged bushing that produces play in the ratchet head, unusual noise, or rough ratcheting action requires replacement to restore smooth, precise ratchet head performance.
Using a genuine Milwaukee OEM bushing ensures the correct dimensional specification, QPQ surface treatment, and material for the shaft or pin interface it serves within the M12 FUEL ratchet head. Non-OEM bushings may not match the original surface treatment or dimensional tolerances, leading to accelerated wear or increased play in the ratchet head assembly. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct bushing for your specific unit.
