Milwaukee Gearcase Assembly 018762
Model Number: 14-29-0001
The Milwaukee 14-29-0001 is a genuine OEM Gearcase Assembly, service number 018762, for the Milwaukee 3670-20, 3671-20, and 3672-20 cordless grinders. The gearcase assembly is the complete housing and internal geartrain unit that encloses the speed-reduction gears between the motor and the tool's output shaft — the precision-machined housing that supports all gear shafts and bearings in their correct positions, contains the gearcase lubricant, and transmits motor rotation to the output at the correct speed and torque ratio. The 018762 designation is the specific gearcase service-assembly number for the tools it serves. Providing the gears and housing as a complete assembly ensures all components are factory-matched and pre-lubricated for direct installation, rather than having to source and align individual gears, bearings, and the housing separately. A worn, cracked, or failed gearcase assembly that is causing gear noise, lubricant leakage, or loss of output power requires replacement to restore correct gearcase function.
Using a genuine Milwaukee OEM gearcase assembly ensures the correct gear ratio and housing interface for the tool it serves. This assembly is specified for the 3670-20, 3671-20, and 3672-20 cordless grinders, but because Milwaukee changes service parts by production revision as well as by catalog number, the correct gearcase can differ between serial-number runs of the same grinder. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct assembly for your specific unit, and inspect the surrounding gears, bearings, and output components when servicing the gearcase, since these parts work together.

Please note: several of the screw holes in this gearcase assembly are unthreaded by design. They are intended for self-tapping (thread-forming) screws that cut their own threads as they are driven in, so these holes arrive without pre-cut threads. Unthreaded holes on this assembly are normal and are NOT a defect or a manufacturing error. Use the correct self-tapping screws shown in the tool's parts diagram and drive them into the original hole locations so the threads form correctly. Always verify by serial number using Milwaukee's online parts lookup before ordering.
