Harley-Davidson crank webs ("flywheels") are made of (steel) castings. To prevent the connecting rods themselves and the bearing cages of the big-end bearing from running directly against them, thrust washers are installed in the crank webs. These thrust washers are also used to set the side clearance of the big-end bearing and the connecting rod eye. Installing our thrust washers for the connecting rod bearing as a replacement for worn OEM parts is therefore a bit “tricky”: the connecting rod side clearance should be measured with a feeler gauge after tightening the crank pin nuts and adjusted if necessary.
