The Muncie A20 Series 10-Bolt Clutch Shift Power Take-Off, part number A20-A1005-HX11XPX or A20A1005HX11XPX, is a medium-duty PTO engineered specifically for Allison 3000 and 4000 Series transmissions. This unit runs a 0.54:1 gear ratio with electric/hydraulic shift activation, right-hand mounting, and a 1-1/4" keyed output shaft. The shift cover allows 360-degree rotation for flexible installation routing, and the rotatable pump flange adds further positioning versatility. Tapered roller bearings extend service life, and the increased output shaft diameter handles higher drive loads. The A20 Series carries a single intermittent/continuous torque rating and is compatible with Muncie's EX Drive shaft extension. Call us to confirm proper fit for your application.
