The Muncie A20-A1010-HR3BBPX or A20A1010HR3BBPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 series transmissions. The A20 series uses a proven clutch pack design with tapered roller bearings to extend service life, and the shift cover rotates a full 360 degrees for flexible installation. The rotatable pump flange, increased output shaft diameter, and extended-length PTO mounting fasteners address common fit and durability concerns on heavy-duty truck applications. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Reduced leak paths and a maximized gear profile keep noise and fluid management in check. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
