Flywheel Washers

13 products

Flywheel Washers for Harley-Davidson are essential engine components used during crankshaft assembly and rebuild work. These washers are primarily designed for vintage 45-inch side-valve flathead motors, making them indispensable for restorers working on classic WL and Servi-Car machines. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks flywheel washers from MCS, providing accurately dimensioned replacements that meet original specifications. When rebuilding a flathead bottom end, using the correct flywheel washers ensures proper crankshaft alignment and bearing preload, which directly affects engine smoothness and service life.
