The Chelsea 880 Series Power Take-Off Assembly, part number 880XMAHX-H4XS or 880XMAHXH4XS, is an 8-bolt, lever mechanical shift PTO designed for heavy-duty applications including bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. It mounts to manual transmissions with an 8-bolt aperture from Volvo/Mack, Allison, Eaton/Fuller, and other manufacturers. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange. Intermittent torque rating for the 880 Series reaches 500 lb-ft (678 Nm); verify your specific application torque on Chelsea's application pages. Shaft power output is 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing delivers long service life, and the removable shift cover makes backlash adjustment straightforward at installation. Call us to confirm proper fit for your transmission and application.
The Chelsea 880 Series is suited for constant-mesh, high-torque applications across oil and gas, aerial, mining, on-highway, and other mobile markets. Typical applications include bulk haulers, winch systems, fire apparatus, oil field equipment, aerial equipment, and large truck recovery. Continuous operation is supported with a 30% de-rating applied to the intermittent torque rating. Tapered cone bearings support excellent load-bearing performance. The 880 Series is compatible with a wide range of transmissions, including the Eaton Endurant. For application-specific torque ratings and transmission compatibility details, consult the Chelsea 880 Series application pages or contact Pro Gear and Transmission.
