The Muncie A20-A1007-JX32I or A20A1007JX32I is a medium-duty, clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. Part of Muncie's A20 Series, it mounts via a 10-bolt pattern and features a shift cover with 360-degree rotation for flexible installation. A rotatable pump flange and increased clearance simplify mounting in tight spaces. Tapered roller bearings extend service life, and an enlarged output shaft diameter adds durability. The unit supports three housing arrangements and is compatible with the EX Drive shaft extension. Single intermittent and continuous torque ratings apply across the range, so one rating covers both duty cycles. Call us to confirm the right configuration for your transmission and application.
