A20-A1006-HR3PBPX Muncie 10-Bolt Clutch Shift PTO

The Muncie A20-A1006-HR3PBPX or A20A1006HR3PBPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, giving installers flexibility in routing and orientation, while the rotatable pump flange and extended-length PTO mounting fasteners reduce installation time. Tapered roller bearings extend service life, and an increased-diameter output shaft adds durability under sustained load. A single intermittent/continuous torque rating simplifies application planning. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Call us to confirm the correct speed ratio and housing arrangement for your specific application.
