The Chelsea 680 Series Power Take-Off, part number 680ZSDAX-A5RB or 680ZSDAXA5RB, mounts to transmissions with an 8-bolt PTO aperture and is compatible with Eaton/Fuller, Volvo/Mack, and other transmission manufacturers. It uses wire/cable mechanical shifting and delivers a 1-1/4" round output shaft with keyway. Intermittent torque is rated at 375 lb-ft (508 Nm) per application pages. Shaft power output reaches 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. The cast iron housing and tapered cone bearings on the output shaft suit higher-torque work like pneumatic blowers. A deep-mount housing option is available for Mack transmission installations. Call us to confirm proper fit for your specific transmission configuration.
The Chelsea 680 Series suits vocational applications including aerial lifts, dump trucks, refuse vehicles, snow and ice removal equipment, fire and rescue apparatus, service trucks, and blower and product pump systems. The cast iron housing and tapered cone bearings on the input shaft deliver greater load-bearing capability compared to needle-bearing designs. Thirty-two output options and four internal speed ratios give this series flexibility across a range of pump and driveline configurations. Continuous operation is supported with a 30% de-rating applied.
