The Muncie A20 Series power take-off, part number A20-A1008-HR3BBPX or A20A1008HR3BBPX, is a medium-duty clutch shift PTO engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible mounting, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings extend service life, while an increased-diameter output shaft handles higher torque loads. The gear geometry is designed to minimize noise, and reduced leak paths cut maintenance time. Three housing arrangements give installers positioning flexibility, and extended-length PTO mounting fasteners ease installation clearance. The unit is also compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your specific application.
