Crankshaft: Testing and Inspection
End Play
1. Install crankshaft into cylinder block.
2. Pry crankshaft toward rear of engine.
3. Install Dial Indicator with Bracketry 100-002 (TOOL-4201-C) or equivalent so contact point rests against crankshaft flange and indicator axis is
parallel to crankshaft axis.
4. Zero the dial indicator. Push crankshaft forward and note reading on dial.
5. If the end play exceeds the wear limit listed in the specifications, replace the lower crankshaft thrust main bearing and crankshaft thrust washer (if
equipped). Inspect the crankshaft for damage to the thrust face before installing the new crankshaft thrust main bearing and crankshaft thrust
washer (if equipped). If the end play is less than the minimum limit, inspect the thrust bearing faces for scratches, burrs, nicks or dirt. If the thrust
faces are not damaged or dirty, they probably were not aligned properly. Lubricate and install the lower crankshaft thrust main bearing and
crankshaft thrust washer (if equipped). Align the faces, following Main Bearing Replacement procedure.
