Milwaukee Locking Shuttle
Model Number: 45-24-1255
The Milwaukee 45-24-1255 is a genuine OEM Locking Shuttle service part for use in compatible Milwaukee tools. A locking shuttle is the sliding control element that moves through a track in the tool housing to engage or disengage a mechanical lock. Depending on the tool, that lock may hold a trigger in the off position as a safety lock-out, hold a switch on for continuous running, or index a selector into a chosen mode position. The shuttle itself is the part the operator's thumb contacts, and it carries the internal detent features and lock tabs that actually do the work once the shuttle reaches the end of its travel. Because it is a molded control that sits proud of the housing, it takes direct impact whenever the tool is dropped, set down hard, or knocked against framing, and it collects dust and grit in its track under normal jobsite use. The most common failures are a shuttle that will not travel its full range, one that no longer holds its position at either end, one that feels gritty or binds partway through its stroke, and one that has cracked or broken off entirely at the thumb pad. Any of these is a functional safety issue as well as a convenience issue, since a lock-out that does not positively engage is a lock-out the operator cannot rely on.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before placing your order, since running production changes can alter part compatibility within the same catalog number. Milwaukee produces a number of visually similar shuttles across the 45-24 and 42-42 part number series, including forward and reverse shuttles, speed selector shuttles, and locking shuttles, and these are frequently not interchangeable even between tools that look closely related, so order by the exact part number shown at the correct figure position on your tool's service parts diagram rather than by visual comparison. Note that on several Milwaukee bulletins the locking shuttle is paired with a separate shuttle spring at the adjacent figure position, and that spring is what returns the shuttle and gives it its detent feel. If your complaint is a shuttle that travels freely but will not hold position, the spring is at least as likely to be the cause as the shuttle itself, and both should be inspected together. The shuttle spring, along with any housing screws that must be removed to access the shuttle, is sold separately, so refer to your tool's parts diagram for the correct part numbers and required quantity.
