The Muncie A20-A1006-HX5BS or A20A1006HX5BS is a medium-duty, clutch shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions via a 10-bolt mount. The shift cover allows 360-degree rotation, and the rotatable pump flange simplifies installation with increased clearance around the mounting area. Tapered roller bearings extend PTO service life, and the enlarged output shaft diameter adds durability under load. Gear geometry is optimized to minimize operating noise. The unit ships with extended-length PTO mounting fasteners and is compatible with the EX Drive shaft extension. Three housing arrangements are available, and the clutch pack design carries a single intermittent/continuous torque rating. Call us to confirm the correct housing arrangement for your application.
