The Muncie A20 Series 10-bolt clutch shift power take-off, part number A20-A1008-HX3X4PX-E1 or A20A1008HX3X4PXE1, is a medium-duty PTO engineered specifically for Allison 3000 and 4000 Series transmissions. A rotatable pump flange and shift cover with 360-degree rotation simplify plumbing and mounting orientation. The proven clutch pack runs on tapered roller bearings for extended service life, and the increased output shaft diameter handles higher drive loads. Gear geometry is optimized to keep noise down, while extended-length mounting fasteners and increased housing clearance ease installation. The unit is also compatible with the Muncie EX Drive shaft extension for reach-sensitive applications. Call us to confirm proper fit for your specific installation.
