The Muncie A20-A1008-HR1BSPX or A20A1008HR1BSPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation positioning, and the pump flange is also rotatable to suit different hydraulic setups. Tapered roller bearings extend service life, and the increased-diameter output shaft adds durability under load. Muncie's clutch pack design carries a single intermittent/continuous torque rating, reducing guesswork when sizing the PTO for your application. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
