Multiquip BM1810 Pulley Gear Box - OEM Replacement Part for Portable Mixers

The gearbox pulley transfers power from the motor to the mixing drum assembly on battery-powered portable concrete mixers. This precision-machined component is essential for maintaining proper drum rotation speed at 25 rpm, ensuring consistent mixing performance in concrete and mortar production applications.

This pulley mounts directly to the gearbox shaft assembly and works in conjunction with the drive belt system to deliver reliable power transmission. The gearbox shaft connection point is critical—the drum must rotate clockwise and seat fully against the shoulder to prevent thread damage during operation. Regular inspection of the pulley and belt system is recommended, especially before operating with the drive belt cover installed as specified in safety protocols.

Compatible with the following Multiquip portable mixer models:
