The Muncie A20-A1006-HH3BB or A20A1006HH3BB is a medium-duty, clutch-shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover allows 360-degree rotation for flexible installation positioning, and the rotatable pump flange adapts to multiple mounting configurations. Tapered roller bearings extend PTO service life, while an increased-diameter output shaft adds durability under load. Gear geometry is optimized to minimize operating noise, and reduced leak paths lower maintenance demands. The unit accepts three housing arrangements and is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
