The Muncie A20-A1008-SX3BSPX or A20A1008SX3BSPX is a medium-duty, clutch-shift power take-off from the A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions using a 10-bolt mounting configuration. The shift cover rotates a full 360 degrees, and the pump flange is independently rotatable, giving installers flexibility in tight engine bays. Tapered roller bearings extend service life, and the increased-diameter output shaft adds durability at the drive connection. Gear geometry is optimized to reduce operating noise, and reduced leak paths keep the unit cleaner in service. Compatible with the EX Drive shaft extension and available in three housing arrangements. Call us to confirm proper fit for your application.
