The Chelsea 660 Series Power Take-Off, part number 660XSAHP-W3LD or 660XSAHPW3LD, is a 6-bolt mounted PTO built for medium to heavy duty vocational applications. It uses a wire/cable mechanical shift and delivers a 1-1/4" round output shaft with keyway. The 660 Series is rated for intermittent torque up to 375 lb-ft (508 Nm), with shaft power output of 36 HP at 500 RPM, 71 HP at 1000 RPM, and 107 HP at 1500 RPM. One-piece gears and cast iron bearing caps contribute to the series' torque capacity and service life. Tapered cone bearings on the output shaft and tapered bearings on the input shaft handle demanding load cycles. Compatible transmissions include Eaton/Fuller, Volvo/Mack, Hino, and other 6-bolt applications. Call us to confirm proper fit for your transmission and pump configuration.
The Chelsea 660 Series is suited for aerial devices, dump trucks, service trucks, blower and product pumps, and snow and ice removal equipment. The series offers twenty-six output options including a 360-degree rotatable flange for optimal pump positioning, four internal speed ratios, and ten shift options. Vocational markets served include construction equipment, aerial, and municipal applications.
