The Muncie A20-A1007-HR3BBPX or A20A1007HR3BBPX is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is also rotatable, giving installers flexibility in tight engine compartments. Increased output shaft diameter adds durability at the drive end, while tapered roller bearings extend PTO service life. The gear set is designed for reduced operating noise, and reduced leak paths keep fluids where they belong. The unit accepts the EX Drive shaft extension and is available in three housing arrangements. Call us to confirm the right ratio and housing arrangement for your application.
