The Muncie A20 Series 10-Bolt Clutch Shift Power Take-Off, part number A20-A1010-HX3X4PN or A20A1010HX3X4PN, is a medium-duty PTO designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is also rotatable, giving installers real flexibility in tight bays. A proven clutch pack design and tapered roller bearings keep the unit running longer between service intervals. Gear geometry is optimized to keep noise down under load. The A20 accommodates an EX Drive shaft extension and comes in three housing arrangements. Call us to confirm the right configuration for your application.
