The Muncie A20-A1011-HX11XPX or A20A1011HX11XPX is a medium-duty clutch shift power take-off designed for Allison 3000 and 4000 series transmissions. The A20 series mounts via a 10-bolt pattern and features a 360-degree rotating shift cover and rotatable pump flange, giving installers flexibility in tight mounting situations. Increased clearance at the housing simplifies installation, while extended-length PTO mounting fasteners provide a more secure fit. Tapered roller bearings extend service life, and an increased-diameter output shaft handles higher drive loads. The gear design is optimized to minimize operating noise, and reduced leak paths keep the unit cleaner in service. This PTO is also compatible with the EX Drive shaft extension and is available in three housing arrangements. Call us to confirm the correct configuration for your application.
