The Muncie A20-A1012-HX1CBPW-B1 or A20A1012HX1CBPWB1 is a medium-duty, clutch shift power take-off from Muncie's A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions with a 10-bolt mounting interface. The shift cover rotates 360 degrees for flexible installation positioning, and the pump flange is rotatable to suit varying hydraulic plumbing layouts. Tapered roller bearings extend service life, while an enlarged output shaft diameter adds durability under load. The gear set is optimized to reduce operating noise, and extended-length PTO mounting fasteners simplify installation. The unit is also compatible with the Muncie EX Drive shaft extension. Three housing arrangements are available, covering a wide range of installation configurations. Call us to confirm the correct housing arrangement for your application.
