End Play

NOTE: Crankshaft should be installed and main bearing caps torqued to specifications.

1. 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.
2. Pry against the No. 2 main bearing cap and force crankshaft (6303) toward rear of engine.
3. Zero the dial indicator. Push crankshaft forward and note reading on dial. Reading is the end play
4. Determine correction:

If the end play exceeds the wear limit listed in specifications, grind the crankshaft and install an oversize crankshaft thrust main bearing (6337) or washer, or replace crankshaft and crankshaft thrust main bearing or washer.

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 not aligned properly. Lubricate and install a new thrust bearing and align the faces following proper main bearing replacement procedure.

5. Recheck the crankshaft end play after service.
