Starter Motor Shim - 104549
The starter mounting shim, generally gets lost or forgotten when the starter is replaced is used to adjust the position of the starter pinion relative to the ring gear. With early starters, adding a shim moves the pinion away from the ring gear, decreasing the mesh. With late starters, adding a shim brings the pinion closer to the ring gear, increasing the mesh. It seems that most cars were originally fitted with one shim. These are 1.9mm in thickness.
