Description
Overview:
The GXH50 Gearbox Pulley Kit is a genuine Altrad/Belle replacement part for Belle site mixers, designed to restore smooth, reliable drive from the engine to the gearbox. Built from durable metal for long service life, it mounts on the gearbox and works with the drive belt to transmit power for consistent drum rotation. Suited to popular compact mixers such as the Minimix 140 and Minimix 150, it helps maintain mixing performance on small to medium pours. Key dimensions are 150 mm diameter (5.9 inches), 12.2 mm bore/centre hole (0.48 inches), and 20 mm depth (0.79 inches), allowing accurate identification before ordering. Supplied to match the original specification under MPN 900/31600, it is a straightforward like-for-like swap on listed models with no modification required.
