The Muncie A20-A1011-HX31X or A20A1011HX31X is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees and the pump flange is fully rotatable, giving installers flexibility in tight spaces. Increased clearance around the unit simplifies installation, and extended-length mounting fasteners help seat the PTO securely against the transmission pad. Tapered roller bearings support the increased-diameter output shaft for long service life. The gear set is designed to minimize noise, and reduced leak paths cut maintenance calls. Three housing arrangements are available to suit different chassis layouts. Compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and ratio for your application.
