The Muncie A20-A1007-SX5X4BX or A20A1007SX5X4BX is a medium-duty, clutch-shift power takeoff from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions with a 10-bolt mounting pattern. The shift cover rotates 360 degrees for flexible installation, and the pump flange is fully rotatable to suit varied hydraulic plumbing layouts. Tapered roller bearings extend service life, and an increased-diameter output shaft handles higher load demands. The housing is available in three arrangements, and the design includes extended-length PTO mounting fasteners and reduced leak paths. The unit is also compatible with the EX Drive shaft extension.
