The Chelsea 660ZFAHX-V3GF or 660ZFAHXV3GF is a 660 Series Power Take-Off assembly designed for medium- to heavy-duty vocational applications. It mounts via a 6-bolt pattern and uses a wire/cable mechanical shift. The output shaft is a 1-1/4" round configuration, with a keyed option available. Intermittent torque capacity for the 660 Series reaches 375 lb-ft (508 Nm); continuous operation is supported with a 30% de-rating. Shaft power output runs 36 HP at 500 RPM, 71 HP at 1000 RPM, and 107 HP at 1500 RPM. Compatible transmissions include Eaton/Fuller, Volvo/Mack, Hino, and select others. Common applications include dump trucks, aerial devices, service trucks, and snow and ice removal equipment. Call us to confirm proper fit for your specific transmission.
The Chelsea 660 Series is suited for aerial, construction, vocational, and municipal equipment. Output options across the 660 Series include SAE A pump flange, SAE B pump flange, ISO 7652 pump flange, and driveline configurations. Four internal speed ratios and ten shift options are available within the series. Tapered cone bearings on the output shaft and tapered bearings on the input shaft provide strong load-bearing capability. The space-saving shift cover is designed to maximize clearance under the truck. Also referenced as SP660ZFAHX-V3GF in some catalog systems.
