The Muncie A20 Series power take-off A20-A1005-HX3PBPX or A20A1005HX3PBPX is a medium-duty, clutch-shift PTO engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings support extended service life, while an increased output shaft diameter handles higher drivetrain loads. Gear geometry is optimized for reduced operating noise, and extended-length mounting fasteners aid installation. The unit uses a single intermittent/continuous torque rating and is available in three housing arrangements. Compatible with the EX Drive shaft extension.
