Milwaukee Gear Case Assembly for 2604-20
Model Number: 14-29-2604
The Milwaukee 14-29-2604 is a genuine OEM Gear Case Assembly for the Milwaukee M18 Brushless Compact 1/2 in. Hammer-Drill (2604-20). The gear case is the transmission housing that contains the internal planetary gear sets responsible for converting high-speed motor output into the controlled torque and RPM delivered at the chuck. In addition to standard drilling and driving modes, the 2604-20 gear case supports the tool's hammer drilling function — transferring the cam-action hammering mechanism that drives the bit forward with rapid percussion for drilling into masonry, concrete, and hard materials. A cracked gear case housing, stripped gear set, or damaged cam mechanism that causes gear noise, loss of drive, or loss of hammer function requires replacement to restore full drill and hammer drill performance.
Using a genuine Milwaukee OEM gear case assembly ensures the correct gear ratios, hammer cam geometry, bearing fits, and housing dimensions engineered for the 2604-20. Non-OEM gear cases may not replicate the original gear ratios or hammer mechanism tolerances, leading to inconsistent torque output, loss of hammer function, or premature drivetrain failure. Replacing with an OEM gear case assembly restores the 2604-20 to its original transmission specification. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm compatibility with your specific unit.
