The Muncie A20-A1009-H21CBPX or A20A1009H21CBPX is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the rotatable pump flange simplifies plumbing orientation. Extended-length PTO mounting fasteners and increased clearance make installation straightforward. Tapered roller bearings extend service life, and the increased-diameter output shaft handles demanding continuous-duty cycles. The proven clutch pack carries a single intermittent/continuous torque rating, and three housing arrangements give flexibility for different installation envelopes. The unit is also compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your specific Allison transmission configuration.
