The Muncie A20-A1007-JX3BBPX or A20A1007JX3BBPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series mounts with extended-length PTO fasteners and offers three housing arrangements, giving installers flexibility on tight applications. The shift cover rotates 360 degrees, the pump flange is fully rotatable, and increased clearance simplifies installation on crowded firewall areas. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability under sustained load. Gear geometry is optimized to reduce operating noise, and reduced leak paths keep the installation clean. The unit is compatible with the EX Drive shaft extension for added drivetrain reach. Call us to confirm proper fit for your specific transmission configuration.
