The Muncie A20-A1009-HR3BSPX or A20A1009HR3BSPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the pump flange is fully rotatable to simplify hydraulic plumbing. Tapered roller bearings extend PTO service life, while an increased-diameter output shaft adds durability under load. The unit uses a proven clutch pack design with a single intermittent/continuous torque rating, reduced leak paths, and maximized gear geometry for quieter operation. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Call us to confirm the right configuration for your application.
