The Chelsea 880GMAHX-H3GS or 880GMAHXH3GS is an 880 Series Power Take-Off Assembly designed for 8-bolt manual transmission apertures. It delivers up to 500 lb-ft (678 Nm) intermittent torque and is rated for 48 HP at 500 RPM and 95 HP at 1000 RPM. The output shaft is a 1-1/2"-10T spline with a 1410 series companion flange. Shift is lever mechanical, and the 880 Series supports continuous operation with a 30% de-rating. Compatible transmissions include Volvo/Mack, Allison, Eaton/Fuller, and others. The dual-pump output allows mounting a hydraulic pump on each end of the unit. Typical applications include fire trucks, bulk haulers, oil field equipment, winch systems, and large truck recovery. Call us to confirm proper fit for your transmission.
The Chelsea 880 Series PTO is suited for demanding mobile and on-highway applications including bulk haulers, fire trucks, oil field equipment, aerial units, winch systems, and large truck recovery. The series supports a range of output configurations including SAE B and SAE C pump flanges, ISO 7652 pump flange, and driveline outputs. The cast iron housing and tapered cone bearings are designed for high and low speed, high torque service with constant mesh input gears.
