The Chelsea 880 Series Power Take-Off Assembly, part number 880XDAHX-Y5XV or 880XDAHXY5XV, is an 8-bolt PTO rated for up to 500 lb-ft (678 Nm) intermittent torque. It ships with a lever mechanical shift and delivers 56+ HP (51+ kW) output, with shaft power measured at 48 HP at 500 RPM and 95 HP at 1,000 RPM. The output shaft is a 1-1/2"-10T spline paired with a 1410 Series companion flange. Cast iron housing and tapered cone bearings are standard. The removable shift cover simplifies backlash adjustment at installation. This unit fits transmissions with an 8-bolt aperture, including Allison, Eaton/Fuller, Volvo/Mack, and others. Typical applications include bulk haulers, fire trucks, oil field equipment, winch systems, and large recovery trucks. Call us to confirm proper fit for your specific transmission.
The Chelsea 880 Series is designed for high-torque, constant mesh input gear applications across a wide range of heavy-duty vocations including oil field, aerial, mining, fire apparatus, bulk hauling, and large truck recovery. The series supports SAE B, SAE C, and ISO 7652 pump flange output configurations in addition to driveline output, giving this platform flexibility across hydraulic and mechanical drive demands. The X designation in the part number indicates no pressure lube, and the Y5XV suffix encodes specific output and application configuration details - confirm your transmission aperture and output requirements before ordering. Call Pro Gear and Transmission to verify this configuration matches your chassis and hydraulic system.
