The Muncie A20-A1007-SX11X or A20A1007SX11X is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 series transmissions. The A20 Series carries a single intermittent/continuous torque rating across its speed range, simplifying application selection. Speed ratios from 5 through 15 are available across the series, with output HP percentages ranging from 74% to 201% of engine speed on 3000 series transmissions. Three housing arrangements accommodate different installation requirements, and the shift cover rotates a full 360 degrees so the control port can be positioned to suit the chassis. The extended-length PTO mounting fasteners and increased component clearances make installation more straightforward. Call us to confirm the correct ratio and housing arrangement for your specific application.
