The Chelsea 660GHAHX-P3XV or 660GHAHXP3XV is a 660 Series Power Take-Off built for medium- to heavy-duty vocational applications including dump trucks, aerial devices, service trucks, and snow and ice removal equipment. It mounts on 6-bolt transmissions compatible with Eaton/Fuller, Hino, Volvo/Mack, and other manufacturers. The wire/cable mechanical shift activates the PTO without an air line, and the 1-1/4" round output shaft with keyway drives hydraulic pumps or driveline accessories. The 660 Series carries an intermittent torque rating of up to 375 lb-ft (508 Nm) -- check application pages for the actual rating for your specific configuration. Shaft power output 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 transmission.
The Chelsea 660 Series fits most popular manual 6-bolt transmissions and suits demanding vocational markets including aerial, construction, and municipal equipment. Twenty-six output options and four internal speed ratios give this series broad application flexibility. The space-saving shift cover is designed to maximize clearance under the truck. Tapered cone bearings on the output shaft and tapered bearings on the input shaft (rather than needle bearings) are 660 Series design characteristics that contribute to its load-bearing capability. Compatible applications include blower and product pumps, aerial devices, dump trucks and trailers, service trucks, and snow and ice removal equipment.
