The Chelsea 680GFAHX-V3XY or 680GFAHXV3XY is an 8-bolt power take-off from the Chelsea 680 Series, engineered for medium- to heavy-duty manual transmission applications including Eaton/Fuller, Volvo/Mack, and Daimler/Detroit platforms. The 680 Series features a cast iron housing with tapered cone bearings on both the input and output shafts for increased load capacity, making it well-suited to higher-torque demands such as pneumatic blowers. The series offers output power of 56 HP (42 kW) or greater, with shaft power ratings of 36 HP at 500 RPM, 71 HP at 1000 RPM, and 107 HP at 1500 RPM. A deep-mount housing option supports Mack transmission installations. Call us to confirm proper fit for your transmission and application.
