The Muncie A20-A1009-HX3CBPW-H3 or A20A1009HX3CBPWH3 is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation positioning, and the pump flange is fully rotatable to suit your plumbing layout. Tapered roller bearings extend PTO service life, and the increased-diameter output shaft adds durability under load. Gear geometry is optimized for reduced operating noise, and the design uses a single intermittent/continuous torque rating for straightforward application matching. Three housing arrangements are available, and extended-length mounting fasteners come with the unit. Compatible with the Muncie EX Drive shaft extension.
