The Muncie A20-A1008-HX3BBPX or A20A1008HX3BBPX is a medium-duty 10-bolt clutch shift power takeoff designed for Allison 3000 and 4000 series transmissions. It runs a 0.84:1 gear ratio with left-hand rotation and an SAE B 7/8"-13T 2/4-bolt output flange. The shift cover rotates 360 degrees and the pump flange is also rotatable, giving installers flexibility in tight engine bays. Three housing arrangements are available, and the unit ships with a standard hose kit. Tapered roller bearings extend service life, and the enlarged output shaft diameter adds durability under continuous-duty cycles. The gear set is engineered for reduced operating noise. Compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and output configuration for your application.
