The Muncie A20-A1007-HX3BSBX or A20A1007HX3BSBX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is rotatable as well, giving installers flexibility in tight engine compartments. Increased clearance around the unit simplifies installation further. Tapered roller bearings extend service life, and the enlarged output shaft diameter adds durability under sustained load. The gear set is optimized to minimize noise, leak paths are reduced by design, and three housing arrangements let you match the unit to your chassis layout. The A20 series also accepts the EX Drive shaft extension. Call us to confirm proper fit for your application.
