The Muncie A20-A1010-HX1PSPX or A20A1010HX1PSPX is a medium-duty, clutch shift power take-off engineered specifically for Allison 3000 and 4000 series transmissions, mounted via a 10-bolt interface. The A20 series shift cover rotates a full 360 degrees for flexible installation positioning, and a rotatable pump flange adds further plumbing convenience. Tapered roller bearings extend service life, while an enlarged output shaft diameter handles higher drivetrain loads. The clutch pack carries a single rating that covers both intermittent and continuous duty, simplifying application selection. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct configuration for your transmission and application.
