Multiquip EM600131 Output Drive Pinion - OEM Replacement Part for Plaster Mortar Mixers

The output drive pinion is a critical transmission component that transfers power from the engine to the paddle shaft in plaster and mortar mixers. This gear engages with the drivetrain to rotate the mixing drum when the clutch is activated, enabling the 12 cubic foot drum to process mortar and plaster materials effectively. When this pinion wears or strips, symptoms include grinding noises during operation, loss of paddle rotation despite engine running, or complete failure to engage the mixing drum.

This genuine OEM pinion is precision-manufactured to exact Multiquip specifications for the mechanical drive system. The EM12M series features a clutch-engaged paddle shaft that requires forward movement to activate mixing—this output drive pinion is essential to that power transmission system. Regular inspection of the drive components should occur during the mixer's annual gearbox service, which requires draining and refilling 1.27 quarts of gear oil. Replace this pinion at the first sign of tooth wear, chipping, or unusual noise to prevent secondary damage to the gearbox assembly.
