The Muncie A20 Series power take-off, part number A20-A1007-HR1BBPX or A20A1007HR1BBPX, is a medium-duty clutch shift PTO engineered specifically for Allison 3000 and 4000 Series transmissions with a 10-bolt mounting interface. The 360-degree rotating shift cover and rotatable pump flange simplify installation and hydraulic plumbing in tight spaces, while extended-length PTO mounting fasteners add clamping security. Tapered roller bearings and an increased-diameter output shaft extend service life under continuous-duty cycles. The clutch pack carries a single intermittent/continuous torque rating, and three housing arrangements give you flexibility for different chassis configurations. The unit is also compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
