The Chelsea 880 Series Power Take-Off, part number 880QJLZX-V3XY or 880QJLZXV3XY, is an 8-bolt, lever-mechanical shift PTO built for high-torque, heavy-duty applications. Output is through a 1-1/2"-10T spline shaft fitted with a 1410 series companion flange, and the unit delivers up to 500 lb-ft intermittent torque with shaft power rated at 48 HP at 500 RPM and 95 HP at 1000 RPM. A dual-pump output configuration allows a hydraulic pump to be mounted on each end of the PTO simultaneously. The removable shift cover simplifies backlash adjustment during installation. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other 8-bolt manual transmission apertures, the 880 Series is commonly used on bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. A genuine Chelsea part available from Pro Gear and Transmission. Call us to confirm proper fit for your specific transmission.
The Chelsea 880 Series is designed for high and low speed, high-torque applications using constant mesh input gears. Tapered cone bearings provide strong load-bearing capability across demanding service cycles. The series supports continuous operation with a 30% de-rating. Typical applications include bulk haulers, winch systems, fire trucks, oil field equipment, aerial units, and large truck recovery vehicles. The 880 Series is also available for the Eaton Endurant transmission. Contact Pro Gear and Transmission to confirm which 880 Series configuration fits your transmission.
