The Chelsea 880GQAHX-A3XK or 880GQAHXA3XK is a heavy-duty 880 Series Power Take-Off assembly built for 8-bolt manual transmission apertures. It uses a lever mechanical shift and delivers up to 500 lb-ft intermittent torque, with shaft power rated at 48 HP at 500 RPM and 95 HP at 1,000 RPM. The output shaft is a 1-1/2"-10T spline fitted with a 1410 companion flange, and the 8-bolt mounting pattern fits a broad range of transmissions including Eaton/Fuller, Volvo/Mack, and Allison. Constant mesh input gears and tapered cone bearings handle high-torque, high-cycle demands common in fire trucks, bulk haulers, oil field equipment, large recovery trucks, and aerial applications. The removable shift cover simplifies backlash adjustment at installation. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 880 Series is engineered for high-torque, constant-mesh applications across demanding markets including oil and gas, aerial, mining, and on-highway vehicles. Typical applications include bulk haulers, fire trucks, oil field equipment, winch systems, aerial units, and large truck recovery rigs. The 880 Series is available for a wide range of transmissions, including the Eaton Endurant. Lubrication type varies by model configuration (pressure lube or non-pressure lube). Refer to Parker Chelsea documentation including the 880 Series Owner's Manual (HY25-2880-M1_US) and Chelsea Service Manual (HY25-6880-M1/US) for full installation and service guidance.
