Milwaukee Blade Release Shaft Bushing
Model Number: 42-40-0640
The Milwaukee 42-40-0640 is a genuine OEM Blade Release Shaft Bushing replacement for compatible Milwaukee power tools — a precision-machined bearing bushing that supports and guides the blade release shaft in its correct position within the tool's blade change mechanism housing. The bushing provides the controlled sliding or rotating bearing surface for the blade release shaft to move smoothly and precisely through its actuation travel — the bushing's bore must be accurately sized relative to the shaft diameter to allow free movement for reliable blade release activation while preventing the excessive shaft play that would cause imprecise mechanism engagement, binding, or incomplete blade release and retention actions. When the bushing wears from the repeated shaft actuation cycles of professional blade changes, develops oval or scored bore surfaces from debris contamination, or is physically damaged, it must be replaced to restore smooth, reliable blade release mechanism function.
Using a genuine Milwaukee OEM bushing ensures the correct bore diameter tolerance, material hardness, and length for the specific blade release shaft application — a bushing with incorrect bore diameter allows excessive shaft play that causes mechanism binding or unreliable blade retention, while an overly tight bore prevents smooth shaft travel that makes blade changes difficult. Bushing specifications are unique to each tool model and mechanism design. Always verify your specific Milwaukee tool's model number and serial number at milwaukeetool.com before ordering, as bushing specifications vary between Milwaukee tool models.
