The Chelsea 880 Series Power Take-Off, part number 880XRAHP-M4XK or 880XRAHPM4XK, is an 8-bolt, lever mechanical shift PTO built for heavy-duty constant-mesh applications. The output shaft is a 1-1/2"-10T spline fitted with a 1410 companion flange, and the unit delivers up to 500 lb-ft of intermittent torque. Shaft power ratings are 48 HP at 500 RPM and 95 HP at 1,000 RPM, with output power exceeding 56 HP. The cast iron housing seats tapered cone bearings for load carrying, and the removable shift cover allows backlash adjustment without pulling the unit. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other 8-bolt aperture manual transmissions. Call us to confirm proper fit for your application.
The Chelsea 880 Series is suited for bulk haulers, fire trucks, oil field equipment, aerial units, winch applications, and large truck recovery vehicles. The series is available for a wide range of 8-bolt aperture transmissions, including the Eaton Endurant. Tapered cone bearings provide excellent load-bearing capability under sustained heavy-duty use. The 880 Series also supports optional air control shift configurations in addition to the standard lever mechanical shift. For oil and gas, mining, aerial, and on-highway vehicle markets, the 880 Series is a proven platform.
