The Muncie 21T34621 thrust washer is a PTO driveline component used to control end play and bear axial load between rotating gear or shaft surfaces inside a power takeoff unit. It seats against a gear or shaft shoulder to keep proper clearance and reduce wear at the thrust face. Replacing a worn thrust washer during PTO service helps restore correct gear positioning. This is a genuine Muncie part from Pro Gear and Transmission. Specific dimensions are not listed here, so give us a call with your PTO model and we can help confirm this is the correct washer for your application.
