Browning 3MVB54P is a three-groove MVP companion sheave, cast in iron, for A- and B-section V-belts in variable-pitch belt drives. It uses a split-taper bushing bore (P1) that fits shafts from 1/2 in to 1-3/4 in and provides a 5.75 in outside diameter with three grooves for belt engagement. For MVP sizing, the belt-pitch diameters are 5.2 in (A) and 5.7 in (B), enabling selectable drive ratios in Browning MVP systems.
