The Muncie 18T42639 is a genuine Muncie thrust washer designed for Muncie power takeoff (PTO) units. Thrust washers control axial load and maintain proper clearance between rotating components inside the PTO assembly, making this a critical wear item during overhaul or repair. If you are servicing a Muncie PTO and need to verify this is the correct thrust washer for your specific unit, call Pro Gear and Transmission and we can help confirm proper fitment before you order.
