Milwaukee Bushing
Model Number: 42-40-0019
The Milwaukee 42-40-0019 is a genuine OEM Bushing for the 2726-20 M18 FUEL Hedge Trimmer. A bushing is a precision-bored sleeve bearing that supports a shaft or fastener, providing a low-friction wear surface between a moving component and the housing or frame that carries it. On the 2726-20 this bushing is documented at the front of the tool alongside the 24 in. blade assembly and its mounting cap screws, where it supports the blade drive and mounting hardware against the loads and vibration of the reciprocating cutting action. 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 fastener, or the surrounding casting. Over the service life of the trimmer the bore gradually opens up from vibration, dust and debris ingress, and normal cycling, and once clearance exceeds the design tolerance the supported component begins to move off center. That shows up as play at the blade mounting, added vibration, uneven wear, and noise under load. Replacing a worn bushing with the correct genuine Milwaukee OEM part restores the original bore diameter and running clearance, which is the reliable way to bring the assembly back into proper alignment and keep the wear from spreading into more expensive adjacent components.
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. This bushing is documented at Figure 2 on bulletin 54-49-2700 for the 2726-20 with serial number H34A, and Milwaukee specifies a quantity of two per tool, so the trimmer uses two bushings and both should be replaced together as a matched set. On the parts diagram the bushings pair one-to-one with the M5 x 0.8 x 30 4mm Hex Cap Screws at Figure 3, which are also used in a quantity of two and are ordered separately as 05-75-0012. Milwaukee uses distinct part numbers to differentiate bushing bore diameter, outside diameter, length, and material across its tools, so bushings that look nearly identical side by side are frequently not interchangeable - order by the exact part number shown at the correct figure position on your tool's service parts diagram rather than by visual comparison.
