Crankshaft End Play

1. Force crankshaft (6303) toward rear of engine.

2. Install Rotunda Dial Indicator with Bracketry 014-00282 or equivalent so contact point rests against crankshaft flange and indicator axis is parallel to crankshaft axis.
   
   
   
   

3. Zero dial indicator. Push crankshaft forward and note reading on dial.

4. If the end play exceeds the wear limit listed in the specific engine section, replace the crankshaft thrust main bearing (6337) . 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 the thrust faces are not damaged or dirty, they probably were not aligned properly. Lubricate and install the crankshaft thrust main bearing and align the faces, following Crankshaft Main Bearing Replacement procedure in Section 03-01A (3.8L) or Section 03-01B (5.0L).
