The Muncie Power Products A20-A1006-HX11XPX or A20A1006HX11XPX is a medium-duty 10-bolt clutch shift power takeoff engineered for Allison 3000 and 4000 series transmissions. It runs a 0.63:1 gear ratio with electric/hydraulic actuation, right-hand mounting, and a 1-1/4" keyed output shaft. The shift cover rotates 360 degrees and the pump flange is fully rotatable, giving installers flexibility in tight engine tunnels. Three housing arrangements are available to match different mounting needs. Tapered roller bearings extend service life, and the enlarged output shaft diameter adds durability under sustained PTO loads. An extended-length mounting fastener package and compatibility with the EX Drive shaft extension round out the design. Call us to confirm the correct housing arrangement and output configuration for your application.
