Product Description
Milwaukee Belt Pulley Kit for MXF314
Model Number: 42-70-0012
The Milwaukee 42-70-0012 is a genuine OEM Belt and Pulley Assembly replacement kit for the Milwaukee MX FUEL 14 in. Cut-Off Saw (MXF314). The belt and pulley assembly is the drive component that transfers POWERSTATE Brushless Motor output to the blade spindle, maintaining the 5,350 RPM no-load speed needed to cut through concrete, rebar, and ductile iron. Under the extreme load and heat of heavy-duty cut-off sawing, drive belts are a wear item — a stretched, cracked, glazed, or broken belt results in loss of blade speed, slipping under load, or complete loss of drive to the blade. Replacing the belt and pulley assembly restores full motor-to-blade power transfer and cut performance to Milwaukee's original specification.
Using a genuine Milwaukee OEM belt and pulley kit ensures the correct belt length, pulley diameter, and material specification engineered for the MXF314's drive system. Non-OEM belts and pulleys may not match the original drive geometry, leading to belt slippage, premature wear, or misalignment under the cutting loads of concrete and rebar applications. 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.
