The Chelsea 880GRAHX-M3XV or 880GRAHXM3XV is an 880 Series Power Take-Off assembly designed for heavy-duty 8-bolt manual transmission applications. It uses a lever mechanical shift and delivers up to 500 lb-ft (678 Nm) intermittent torque, with shaft power rated 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 companion flange. A cast iron housing and tapered cone bearings handle demanding cycles found in bulk hauling, fire apparatus, oil field, aerial, and large truck recovery work. The removable shift cover simplifies backlash adjustment during installation. Dual-pump output lets you mount a hydraulic pump on each end of the PTO. Call us to confirm proper fit for your transmission before ordering.
The Chelsea 880 Series is suited for bulk haulers, fire trucks, oil field equipment, aerial units, winch applications, and large truck recovery vehicles. The 880 Series supports multiple output configurations across the product line, including SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline outputs. This specific assembly, 880GRAHX-M3XV, carries the 1410 companion flange with 1-1/2"-10T spline output. The constant mesh input gears are designed for both high-speed and high-torque cycles. Compatible with a wide range of 8-bolt manual transmissions; contact Pro Gear and Transmission to verify fitment for your specific application.
