The Chelsea 880GJAHX-A3AF is an 880 Series 8-bolt power take-off assembly built for high-torque, heavy-duty applications including bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery vehicles. Shift type is lever mechanical, and the output shaft is a 1-1/2"-10T spline paired with a 1410 series companion flange. Intermittent torque rating for the 880 Series reaches up to 500 lb-ft (678 Nm); check application pages for the confirmed rating for your specific installation. Shaft power output is 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing accepts an 8-bolt transmission aperture and supports dual-pump output, allowing a hydraulic pump to be mounted on each end. A removable shift cover makes backlash adjustment straightforward. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your transmission.
The Chelsea 880 Series is designed for continuous operation with a 30% de-rating applied. Compatible transmissions span Eaton/Fuller, Volvo/Mack, Allison, and others. The 880 Series supports SAE B, SAE C, and ISO 7652 pump flange output configurations across the product family; this unit is configured with a 1410 companion flange. Tapered cone bearings provide load-bearing capability suited to high-torque intermittent service in oil field, aerial, fire, and recovery applications.
