The Muncie A20-A1008-HX3CBPW or A20A1008HX3CBPW is a medium-duty 10-bolt clutch shift power takeoff designed for Allison 3000 and 4000 series transmissions. It runs a 0.84:1 gear ratio with electric/hydraulic shift engagement and a left-hand mounting configuration. The extended-mount wet spline shaft (XSMC) feeds hydraulic or mechanical accessories directly. A 360-degree rotating shift cover and rotatable pump flange simplify positioning during installation, while extended-length mounting fasteners and increased output-shaft diameter address common installation and durability pain points. Tapered roller bearings and a proven clutch pack design reduce internal wear over service life. Compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
