The Chelsea 880XGAHX-A3XK or 880XGAHXA3XK is an 880 Series Power Take-Off assembly built for heavy-duty, high-torque applications on manual transmissions with an 8-bolt aperture. It uses a lever mechanical shift and delivers a 1-1/2"-10T spline output shaft with a 1410 companion flange, rated at up to 500 lb-ft intermittent torque (678 Nm). Shaft power runs 48 HP at 500 RPM and 95 HP at 1000 RPM. Compatible transmissions include Volvo/Mack, Allison, Eaton/Fuller, and others. The cast iron housing carries tapered cone bearings, and the removable shift cover makes backlash adjustment straightforward. Typical applications include fire trucks, bulk haulers, oil field equipment, aerial units, and large recovery trucks. Call us to confirm proper fit for your application.
The Chelsea 880 Series is designed for demanding on-highway and off-highway environments including oil and gas, aerial, mining, and mobile equipment. The series supports SAE B, SAE C, and ISO 7652 pump flange output configurations across the broader model range. Constant mesh input gears maintain engagement across high and low speed conditions. Applications include bulk haulers, winch systems, fire apparatus, oil field trucks, aerial platforms, and large recovery vehicles.
