The Muncie A20-A1009-SX11XPX or A20A1009SX11XPX is a medium-duty, clutch shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions via a 10-bolt mounting. The shift cover rotates a full 360 degrees, and the pump flange is fully rotatable, giving installers flexibility that fixed-mount designs do not offer. Increased housing clearance and extended-length PTO mounting fasteners simplify installation in tight engine bays. Internally, tapered roller bearings extend service life, a proven clutch pack handles engagement, and a maximized gear profile keeps noise down. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension for applications that need it. Call us to confirm the right housing arrangement and ratio for your application.
