The Muncie 21T35143 is a 5/16 lockwasher used in Muncie power takeoff assemblies. Lockwashers at this size serve as fastener retention hardware, keeping bolts and screws secured against loosening under vibration and load typical in PTO-equipped truck drivetrains. If you are sourcing replacement hardware for a Muncie PTO and need to confirm this is the correct piece for your unit, Pro Gear and Transmission carries genuine Muncie parts and can help you verify the right fit. Call us with your PTO model and serial number to confirm compatibility before ordering.
