The Chelsea 680 Series Power Take-Off, part number 680XRAHX-V5XD or 680XRAHXV5XD, is built for medium- to heavy-duty vocational applications demanding higher torque output. It mounts via an 8-bolt aperture and fits transmissions from Eaton/Fuller, Volvo/Mack, and other compatible manufacturers. The wire/cable mechanical shift and 1-1/4" round output shaft (with keyway) make this unit a practical choice for pneumatic blower trucks, dump trucks, aerial equipment, and refuse vehicles. Shaft power output runs 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. Intermittent torque is rated in the 301-400 lb-ft range; check application pages for the actual torque rating specific to this configuration. A deep-mount housing option supports Mack transmission installations. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 680 Series is designed for vocational markets including aerial, dump truck, refuse, fire and rescue, snow and ice removal, service trucks, and blower and product pump applications. The series features a cast iron housing with tapered cone bearings on the output shaft for load-bearing strength. The input shaft also uses tapered bearings rather than needle bearings. Continuous operation is supported with a 30% de-rating applied. The 680 Series offers 32 output options across the family, four internal speed ratios, and ten shift options. The space-saving air shift cover is designed to maximize clearance under the truck.
