Multiquip BM1300 Gear Box - OEM Replacement Part for Portable Mixers

The gear box is the critical power transmission assembly that transfers rotational force from the motor to the mixing drum shaft, enabling proper mixing operation in portable concrete mixers. This component houses the internal gearing that reduces motor speed to optimal mixing RPM while multiplying torque for effective material blending.

According to Multiquip service documentation, the gearbox requires oil replacement every 6 months to maintain proper lubrication and prevent premature wear. During drum removal procedures, the mixing drum detaches by rotating counterclockwise from the gearbox shaft. Regular maintenance of the gearbox oil is essential for extending service life and preventing costly downtime. Signs that gearbox replacement may be needed include unusual grinding noises, oil leaks around seals, excessive heat during operation, or difficulty in drum rotation.

This gear box is compatible with the following Multiquip portable mixer model:
