The Chelsea 880 Series Power Take-Off Assembly, part number 880XQAHX-P3XY or 880XQAHXP3XY, is an 8-bolt, lever mechanical shift PTO built for heavy-duty, high-torque applications. It delivers up to 500 lb-ft of intermittent torque and produces 48 HP at 500 RPM or 95 HP at 1,000 RPM through a 1-1/2"-10 spline output shaft paired with a 1410 companion flange. The removable shift cover allows straightforward backlash adjustment during installation. A cast iron housing and tapered cone bearings handle demanding service in applications such as fire trucks, bulk haulers, oil field equipment, aerial units, and large recovery trucks. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other 8-bolt manual transmissions. Call us to confirm proper fit for your specific transmission.
The Chelsea 880 Series is suited for bulk haulers, fire trucks, oil field rigs, aerial equipment, winch systems, and large truck recovery. The series supports continuous operation with a 30% de-rating. Tapered cone bearings provide load-bearing performance across high-speed and high-torque conditions. The 880 Series is also available for the Eaton Endurant transmission. Output flange options across the series include SAE B, SAE C, and ISO 7652 pump flanges in addition to the driveline output on this assembly. Parker Chelsea documentation for the 880 Series includes the 880 Series Owner's Manual, 880 Series Parts List (HY25-2880-M1_US), and the Chelsea Service Manual (HY25-6880-M1/US).
