The Muncie B1559-A or B1559A is a return port cover designed for Muncie power takeoff units. This cover fits over the return port on the PTO housing, keeping the port sealed when not in use. Muncie PTOs are found across a wide range of vocational truck applications, and maintaining proper port coverage helps protect internal components from contamination. If you need help confirming this is the correct cover for your specific PTO model, give Pro Gear and Transmission a call before ordering.
