The Muncie A20-A1007-SX3X4 or A20A1007SX3X4 is a medium-duty, clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern pairs with a shift cover that allows 360-degree rotation, giving installers flexibility on tight engine tunnels. A rotatable pump flange and increased housing clearance further simplify installation. Tapered roller bearings and an increased output shaft diameter extend service life under demanding duty cycles. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and output configuration for your application.
