Description
Overview:
The Key 1/4" Sq x 3/4" is a genuine Altrad/Belle OEM replacement for the drive system of Belle Minipac 300 and MPC300 plate compactors. Made from precision-machined steel, this square-profile shaft key sits in the keyway to lock a hub (such as a clutch, pulley, flywheel, or exciter) to a shaft, preventing slip and ensuring consistent torque transfer. Its dimensions are 1/4 inch square by 3/4 inch long (6.35 mm square by 19.05 mm long), giving a snug, positive fit in correctly sized keyways. Built to withstand vibration and shock loads common in compactors, it helps maintain reliable operation and reduces the risk of downtime. Identified by MPN 06.8.028, it is a straightforward, service-friendly part for routine maintenance and repairs.
