Milwaukee Bushing
Model Number: 42-40-0101
The Milwaukee 42-40-0101 is a genuine OEM Bushing for the M18 FUEL 1-1/2 in. magnetic drill. A bushing is a precision-bored sleeve bearing that supports a rotating or sliding shaft, providing a low-friction wear surface between the moving component and the gearcase that carries it. Because the bushing is intentionally the softer of the two mating surfaces, it is designed to absorb wear that would otherwise transfer to the shaft, the bore, or the gear train it supports, so replacing a worn bushing at service time protects the more expensive components around it. Milwaukee uses distinct part numbers to differentiate bushing bore diameter, outside diameter, length, flange configuration, and material, and bushings that look nearly identical side by side are frequently not interchangeable, 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.
This bushing is identified as the Bushing, Figure 186, on the Milwaukee service parts list for the 2788-20 lineman magnetic drill, bulletin 54-46-0420, and it also serves the 2787-20 standard magnetic drill and the 2787-22, 2787-059, and 2788-22 versions across serial groups G56A, G96A, and G57A. On the service diagram it is installed into the Gear Case Assembly, part number 14-30-0023, before any lubrication is applied, and it sits in the same drive group as the spindle (32-75-0018) and the intermediate gears, so it is reached during a gearcase service rather than as an external swap. When the gearcase is serviced, Milwaukee specifies Type Y grease, number 49-08-5270, with 90 to 95 percent of the old grease removed before new grease is added, and the surrounding shafts, gears, retaining rings, and washers should be inspected and ordered separately as needed. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.

The shafts, gears, retaining rings, and washers this bushing supports are NOT included and are sold separately; refer to the service parts diagram for the correct part numbers. Type Y grease (49-08-5270) is also required for gearcase reassembly and is sold separately. Always verify by serial number using Milwaukee's online parts lookup before ordering, and order by the exact part number, since similar-looking bushings are frequently not interchangeable.
