Milwaukee Gearcase Assembly
Model Number: 44-70-0000
The Milwaukee 44-70-0000 is a genuine OEM Gearcase Assembly, the pump body and gearcase for the Milwaukee 2646 M18 Grease Gun. This assembly is the core of the grease gun's delivery system: the motor drives the gears housed inside it, and those gears drive the pump that pushes grease out of the barrel, through the hose, and into the fitting at working pressure. It carries the full load of the pump and the gear reduction that generates the gun's pressure, so it is the heart of how the tool moves grease. Because it takes the continuous load of pumping thick grease and the wear of the drivetrain, the gearcase can wear, leak, or lose pressure over the tool's life, at which point the gun pumps slowly, weakly, or not at all. Replacing it with the genuine Milwaukee OEM assembly restores full pumping pressure and output with the correct gears, bearings, and bores, where an off-spec or worn unit cannot deliver the gun's rated performance.
This gearcase assembly is the current service replacement for the pump body and gearcase on the Milwaukee 2646-20, 2646-21, and 2646-22 M18 Grease Guns, including the -059 and CT variants. This part replaces obsolete part number 44-70-0112, the earlier Pump Body/Gearcase Assembly, so if your parts diagram still shows 44-70-0112, order 44-70-0000 in its place. It installs with the motor, barrel, and hose assembly that make up the rest of the grease gun, which are separate items. 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.
