Spin the crankshaft one complete rotation. It should spin smoothly throughout.

Attach a dial indicator to the nose of the crankshaft to measure end play.

Use a large flathead screwdriver to carefully move the crankshaft side to side. Zero the indicator at one extreme, then take a measurement at the other extreme.

Crankshaft end play should be 0.0020-0.0098 in (0.050-0.250 mm).

Do not continue if the end play is out of spec. Double check that the thrust washers are installed correctly and of the correct thickness.
