The Chelsea 880 Series Power Take-Off, part number 880XMDAX-V6XS or 880XMDAXV6XS, is a heavy-duty 8-bolt PTO built for high-torque, high-demand applications including bulk haulers, fire trucks, oil field equipment, and large recovery vehicles. It ships with a lever mechanical shift and a 1-1/2"-10T spline output shaft fitted with a 1410 companion flange. Intermittent torque capacity for the 880 Series reaches 500 lb-ft (678 Nm); continuous operation is rated with a 30% de-rating. Shaft power measures 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing accommodates dual-pump output, allowing a hydraulic pump to be mounted on each end. Compatible transmissions include Volvo/Mack, Allison, and Eaton/Fuller among others. A genuine Chelsea part available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 880 Series is designed for heavy-duty on-highway and vocational applications: bulk haulers, winch trucks, fire apparatus, oil field vehicles, aerial units, and large recovery trucks. The 880 features constant mesh input gears for both high- and low-speed operation, and tapered cone bearings for strong load-bearing performance across demanding duty cycles. Compatible with a wide range of 8-bolt transmission apertures, including Eaton Endurant. The dual-pump output configuration allows simultaneous mounting of two hydraulic pumps, one at each end of the PTO output shaft - a practical advantage for complex hydraulic circuits. Parker Chelsea documents for the 880 Series include the 880 Series Owner's Manual, 880 Series Parts List (HY25-2880-M1_US), and Chelsea Service Manual (HY25-6880-M1/US).
