The Chelsea 660 Series Power Take-Off, part number 660ZQAHX-A4XD or 660ZQAHXA4XD, fits most popular manual 6-bolt transmissions and is engineered for medium- to heavy-duty vocational use. This PTO shifts via wire/cable mechanical actuation and delivers an intermittent torque rating up to 375 lb-ft (508 Nm), consult Chelsea application pages to confirm the actual rating for your installation. The 1-1/4" round output shaft (with key) is driven through one-piece gears and supported by tapered cone bearings, giving the 660 Series its load-bearing edge over needle-bearing designs. Compatible transmissions include Eaton/Fuller, Volvo/Mack, and Hino applications. Shaft power reaches 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. Call us to confirm proper fit for your specific transmission.
The Chelsea 660 Series PTO is suited for aerial devices, dump trucks, service trucks, blower and product pump drives, and snow and ice removal equipment. Continuous operation is supported with a 30% de-rating applied. The 660 Series features tapered cone bearings on both the input and output shafts, a step up from needle-bearing designs, for greater load-bearing capability in demanding vocational cycles. Twenty-six output options and four internal speed ratios are available across the 660 Series; call us to confirm that this specific configuration matches your application.
