The Chelsea 880 Series Power Take-Off Assembly, part number 880XGAHP-M6XS or 880XGAHPM6XS, is an 8-bolt, lever mechanical shift PTO built for heavy-duty, high-torque applications. The output shaft is a 1-1/2"-10 spline with a 1410 companion flange, and the unit is rated for intermittent torque in the 401-500 lb-ft range (check application pages for actual torque ratings specific to your transmission). Shaft power is rated at 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing carries tapered cone bearings, and the removable shift cover simplifies backlash adjustment at installation. Compatible with Volvo/Mack, Allison, and Eaton/Fuller transmissions, among others. Typical applications include bulk haulers, fire trucks, oil field equipment, winch systems, and large recovery trucks. Call us to confirm proper fit for your application.
The Chelsea 880 Series is engineered for high and low speed, high torque service using constant mesh input gears. The shift cover is fully removable for straightforward backlash adjustment, reducing installation time in the field. The dual-pump output design allows mounting a hydraulic pump on each end of the PTO, making it well suited for multi-circuit hydraulic systems found on fire apparatus, oil field trucks, and large recovery vehicles. Continuous operation is supported with a 30% de-rating applied. Compatible output flanges across the 880 Series include SAE B, SAE C, and ISO 7652 pump flanges in addition to the driveline-style 1410 companion flange on this assembly.
