Milwaukee Motor Mount Service Kit
Model Number: 44-66-0126
The Milwaukee 44-66-0126 is a genuine OEM Motor Mount Service Kit for the 2840-20 M18 FUEL 2 Gallon Compact Quiet Compressor. This is a kit, not a single part: it contains the hardware that mounts the pump and motor assembly to the compressor frame, specifically four bolts and four vibration dampers. The vibration dampers are the soft isolators that sit between the pump and motor assembly and the frame, absorbing the vibration the pump produces so it is not transmitted into the housing, which is central to the compressor's quiet operation and reduces stress and wear on the mounting points. When the dampers harden, crack, or tear, or the mounting bolts are lost or stripped, the compressor runs louder, vibrates more, and can loosen at the mount, so this kit restores the complete, correct mounting hardware set in one order. Using the genuine Milwaukee OEM kit ensures the correct damper durometer and bolt fit, where off-spec hardware can transmit more vibration or fail to hold the assembly securely.
This kit is identified as the Motor Mount Service Kit, Set of 1, Figure 58 on the Milwaukee service parts list for the 2840-20 compressor, bulletin 54-05-2840, serial L28A and B; the figure number can vary by bulletin revision, so confirm the position against your diagram. The four vibration dampers correspond to the motor mount bushings called out on the diagram, and the kit bundles them with the mounting bolts so the mount can be serviced as a set rather than sourcing each piece individually. Replacing the motor mount involves disconnecting and reconnecting the pump and motor assembly, so note the hose and wire connections while dismantling and match them on reassembly. 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.
