The Chelsea 660XFAHX-H5XD or 660XFAHXH5XD is a 660 Series Power Take-Off assembly built for medium to heavy-duty vocational applications. This 6-bolt PTO mounts to Eaton/Fuller, Hino, Volvo/Mack, and other popular manual transmissions. Shift actuation is wire/cable mechanical. Output shaft is a 1-1/4" round with keyway. The 660 Series carries an intermittent torque rating up to 375 lb-ft (508 Nm), and shaft power reaches 36 HP at 500 RPM, 71 HP at 1000 RPM, and 107 HP at 1500 RPM. The cast iron housing and tapered cone bearings on both the input and output shafts support demanding duty cycles in dump truck, aerial device, and service truck work. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 660XFAHX-H5XD belongs to the 660 Series, a versatile PTO line offering twenty-six output options and four internal speed ratios. The 660 Series is suited for aerial devices, dump trucks, service trucks, snow and ice removal equipment, and blower and product pump applications. The cast iron housing and tapered cone bearings on the input shaft replace the needle bearings found in lighter-duty series, providing greater load-bearing capability. The space-saving shift cover design is intended to maximize clearance under the vehicle. For additional engineering and fitment detail, consult the 660 Series Parts List (HY25-2660-M1_US) or the 660 Series Sales Literature available from Parker Chelsea.
