Udor M164 S164 Gamma Gearbox

The Udor M164-G62 (superseded by the S164-G62, part number 216 510006) is a heavy-duty reduction gearbox engineered to couple petrol or diesel engines to the Udor GAMMA 62 TS GR plunger pump. With a 6.4:1 reduction ratio and 16 HP (12 kW) capacity, this gearbox converts high engine RPM to the lower speed required for optimal pump operation, extending pump life and reducing wear. AES Waterblasters is New Zealand’s authorised Udor distributor, carrying genuine gearboxes and all service parts from our Auckland facility.
