The output shaft is a 1-1/2"-10T spline with a 1410 companion flange, rated for up to 500 lb-ft intermittent torque. Shaft power output reaches 48 HP at 500 RPM and 95 HP at 1000 RPM. The removable shift cover allows straightforward backlash adjustment, and the cast iron housing is designed to handle high-torque, high-cycle service. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other transmission applications. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 880 Series is suited for oil and gas, aerial, mining, on-highway, and other mobile applications. Typical uses include bulk haulers, winch applications, fire trucks, oil field equipment, aerial units, and large truck recovery. The 880 Series features constant mesh input gears and tapered cone bearings for excellent load-bearing performance under high torque and variable speed conditions. Continuous operation is supported with a 30% de-rating applied. Available output flange options across the 880 Series include SAE B, SAE C, and ISO 7652 pump flanges as well as driveline configurations - confirm your specific output requirement against part number 880XRAHX-P3GS before ordering.
