The Muncie A20-A1010-SX1X4 or A20A1010SX1X4 is a medium-duty clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions, mounting via a 10-bolt pattern. The A20 Series design incorporates tapered roller bearings for extended service life, an increased-diameter output shaft for added durability, and a shift cover that allows 360-degree rotation for flexible installation positioning. A rotatable pump flange and increased housing clearance simplify mounting in tight applications. Leak paths are minimized by design, and the gear geometry is optimized to reduce operating noise. The unit shares a single intermittent/continuous torque rating and is available in three housing arrangements. It is also compatible with the EX Drive shaft extension.
