The Chelsea 880 Series Power Take-Off Assembly, part number 880XDITX-V6XV or 880XDITXV6XV, is an 8-bolt, lever mechanical shift PTO rated for up to 500 lb-ft (678 Nm) intermittent torque. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange, and the unit delivers 48 HP at 500 RPM or 95 HP at 1,000 RPM. Designed for heavy-duty applications including bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks, it fits manual transmissions with an 8-bolt aperture from manufacturers including Volvo/Mack, Allison, and Eaton/Fuller. Dual-pump output allows a hydraulic pump to be mounted on each end. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The 880 Series PTO is built for constant mesh input in high-torque, high- and low-speed applications. Typical uses include bulk hauling, winch systems, fire apparatus, oil field equipment, aerial platforms, and large vehicle recovery. The removable shift cover simplifies backlash adjustment for more accurate setup. Tapered cone bearings support demanding load cycles. The dual-pump output configuration allows simultaneous pump mounting on both ends of the unit, making this series a common choice for multi-function hydraulic systems.
