The Chelsea 660 Series Power Take-Off, part number 660GQAHX-V3XD or 660GQAHXV3XD, is a 6-bolt-mounted PTO designed 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) and shaft power of 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. Compatible transmissions include Eaton/Fuller, Volvo/Mack, Hino, and other 6-bolt manual units. Cast iron bearing caps and tapered cone bearings on the output shaft contribute to durability under sustained load. Call us to confirm proper fit for your application.
The Chelsea 660 Series suits demanding vocational equipment including dump trucks, aerial devices, service trucks, snow and ice removal equipment, and blower and product pump applications. The series features tapered cone bearings on the output shaft and tapered bearings on the input shaft, improving load-bearing capability over needle-bearing designs. Continuous operation is supported with a 30% de-rating applied. The 660 Series offers 26 output options and four internal speed ratios across the full series lineup.
