Cougar/XR7 V8-4.6L VIN W (1997)
Crankshaft: Testing and Inspection
End Play
1. Install crankshaft (6303) into cylinder block (6010).
2. Pry crankshaft toward rear of engine.
3. Install Dial Indicator with Bracketry 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, replace the lower 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 lower
crankshaft thrust main bearing and crankshaft thrust washer (6334).
