The Muncie A20-A1012-SX11XPX or A20A1012SX11XPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation positioning, while the rotatable pump flange and increased housing clearance further simplify mounting. Tapered roller bearings extend service life, and an enlarged output shaft diameter adds durability under load. The clutch pack uses a proven design with a single intermittent/continuous torque rating, reducing confusion when speccing hydraulic systems. Gear geometry is optimized to minimize operating noise, and reduced leak paths keep maintenance intervals in check. Three housing arrangements and compatibility with the EX Drive shaft extension give this unit broad installation flexibility. Call us to confirm the right configuration for your application.
