The Muncie A20 Series power take-off A20-A1006-HX3BBUS or A20A1006HX3BBUS is a medium-duty, 10-bolt clutch shift PTO engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees for flexible mounting, and the pump flange is also rotatable to simplify hydraulic plumbing. Three housing arrangements give installers configuration options, while extended-length PTO mounting fasteners and increased installation clearances reduce bench time. Tapered roller bearings extend service life, and an enlarged output shaft diameter handles higher drive loads. The gear set is optimized to minimize operating noise, and a reduced-leak-path design keeps fluids where they belong. This unit is compatible with the EX Drive shaft extension. Call us to confirm the right ratio and configuration for your application.
