The Chelsea 880XBAKP-H6XS or 880XBAKPH6XS is an 880 Series Power Take-Off Assembly built for 8-bolt manual transmission apertures. It uses a lever mechanical shift and delivers a 1-1/2"-10T spline output paired with a 1410 companion flange, rated for intermittent torque in the 401-500 lb-ft range (up to 500 lb-ft; verify exact rating on Chelsea application pages). Shaft power output reaches 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing carries tapered cone bearings, and the removable shift cover allows straightforward backlash adjustment. Typical applications include bulk haulers, fire trucks, oil field equipment, large recovery trucks, and aerial units. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your specific transmission.
The Chelsea 880 Series is designed for high-torque, constant-mesh input applications across oil and gas, aerial, mining, on-highway, and other mobile markets. Common platform applications include bulk haulers, winch systems, fire trucks, oil field equipment, aerial units, and large truck recovery vehicles. The 880 Series supports continuous operation with a 30% torque de-rating applied. Multiple output flange and spline configurations are available across the 880 Series lineup; this unit (880XBAKP-H6XS) is configured with a 1410 companion flange and 1-1/2"-10T spline output. Refer to Chelsea application pages for transmission-specific gear ratios and confirmed torque ratings before installation.
