The Chelsea 660XSAHX-A3XK or 660XSAHXA3XK is a 660 Series Power Take-Off assembly built for medium to heavy duty vocational applications. The 660 Series fits most popular manual 6-bolt transmissions and is compatible with Eaton/Fuller, Hino, Volvo/Mack, and other transmission manufacturers. This unit ships with a 1-1/4" round output shaft with keyway and uses a wire/cable mechanical shift. Intermittent torque capacity for the 660 Series reaches 375 lb-ft (508 Nm); continuous operation is supported with a 30% de-rating applied. Shaft power output at 1,000 RPM is 71 HP (53 kW), reaching 107 HP (80 kW) at 1,500 RPM. The cast iron housing with tapered cone bearings on the output shaft and strong tapered bearings on the input shaft distinguish the 660 from lighter-duty series. Available from Pro Gear and Transmission. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 660 Series is suited for aerial devices, dump trucks, service trucks, snow and ice removal equipment, blower and product pump applications, and other vocational and municipal equipment. Four internal speed ratios and ten shift options are available across the 660 Series, along with 26 output configurations including Chelsea's 360-degree rotatable flange for flexible pump positioning. Refer to Chelsea 660 Series application pages to confirm the correct torque rating and speed ratio for your specific installation.
