The Chelsea 660 Series Power Take-Off, part number 660GSAHX-A3XV or 660GSAHXA3XV, is a 6-bolt mechanical and wire/cable-shift PTO designed for medium- to heavy-duty vocational applications including dump trucks, aerial devices, service trucks, and snow removal equipment. It fits transmissions from Eaton/Fuller, Volvo/Mack, Hino, and other compatible manufacturers. Intermittent torque capacity reaches 375 lb-ft (508 Nm); for continuous operation, a 30% de-rating applies. The 1-1/4" round output shaft with key delivers 71 HP at 1,000 RPM and 107 HP at 1,500 RPM. Cast iron construction with tapered cone bearings on both the input and output shafts contributes to load-bearing strength and service life. Call us to confirm proper fit for your transmission and application.
The 660GSAHX-A3XV is part of Chelsea's 660 Series, which offers four internal speed ratios, twenty-six output options, and ten shift configurations. Applications include blower and product pumps, aerial devices, service trucks, dump trucks and trailers, and snow and ice removal equipment. The series features tapered cone bearings on the output shaft and tapered bearings on the input shaft for greater load-bearing capability compared to needle-bearing designs.
