The Muncie A20-A1010-SX11XPX or A20A1010SX11XPX is a medium-duty, clutch shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions using a 10-bolt mounting pattern. The shift cover rotates 360 degrees, and the rotatable pump flange simplifies installation in tight engine compartments. Increased clearance over earlier designs makes fitment easier, while extended-length PTO mounting fasteners and three available housing arrangements give you flexibility for different truck configurations. Tapered roller bearings extend service life, and the increased-diameter output shaft handles higher drive loads. The unit is compatible with the EX Drive shaft extension. Call us to confirm the right housing arrangement for your application.
