The Muncie A20-A1008-HX32IPX or A20A1008HX32IPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series mounts with extended-length PTO fasteners and offers three housing arrangements, so the unit can be positioned to suit tight engine compartments. A rotatable pump flange and shift cover with 360-degree rotation give installers real flexibility during setup. Tapered roller bearings extend service life at the output shaft, which features an increased diameter for added durability. The proven clutch pack design carries a single intermittent/continuous torque rating across operating speeds, and the optimized gear geometry keeps noise levels down. Compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
