Transmission Thrustwashers

16 products

Transmission Thrustwashers for Harley-Davidson control the end play of shafts and gears inside your gearbox, maintaining correct clearances for smooth shifting. Available from Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, these thrustwashers cover five-speed Big Twin, 45-inch Flathead and classic four-speed transmissions. MCS and Samwel supply precision-ground steel and bronze thrustwashers in the exact thicknesses needed to set end play within factory specifications. Worn thrustwashers allow excessive shaft movement that causes clunky gear changes and accelerated wear, so checking and replacing them during any gearbox rebuild is essential.
