The Muncie Power Products A20-A1010-HX3BBPX or A20A1010HX3BBPX is a medium-duty 10-bolt clutch shift power takeoff designed for Allison 3000 and 4000 series transmissions. It runs a 0.97:1 gear ratio with electric/hydraulic shift, left-hand rotation, and an SAE B 7/8"-13 tooth output configured for 2- or 4-bolt pump mounting. The rotatable pump flange and 360-degree rotating shift cover give installers real flexibility in tight mounting situations, while extended-length PTO mounting fasteners and increased output shaft diameter address two common durability failure points. Tapered roller bearings, maximized gear geometry for noise reduction, and reduced leak paths round out the design. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right housing arrangement for your application.
