End Play

1. Force crankshaft toward rear of engine.
2. 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.





3. Zero the dial indicator. Push crankshaft forward and note reading on dial.
4. If the end play exceeds the wear limit listed for the specific engine, replace the crankshaft sprocket. Inspect the crankshaft for damage to the thrust face before installing the new crankshaft thrust main bearing. If the end play is less than the minimum limit, inspect the thrust bearing faces for scratches, burrs, nicks or dirt. If thrust faces are not damaged or dirty, the crankshaft thrust main bearings were probably not aligned properly. Lubricate and install the thrust bearing and align the faces following Main Bearing Replacement procedure. Check the crankshaft end play.
