590192 Thrust washer, 3rd gear transmission mainshaft

This thrust washer is specifically designed for the 3rd gear on the transmission mainshaft of 1986 to 1990 4-speed XL Sportsters. Replacing OEM 35356-86, it is a critical component for maintaining the correct lateral spacing of the gear set. In the high-stress environment of a Sportster gearbox, these washers prevent metal-on-metal wear and ensure that the gears remain properly aligned for smooth engagement. If you are experiencing noise in third gear or performing a full transmission overhaul, replacing these washers is a standard practice to ensure long-term reliability. This MCS part is sold as a pack and is manufactured to meet original tolerances for a perfect fit.
