Crankshaft: Testing and Inspection
Runout
1. Set V-blocks on surface plate and set crankshaft on V-blocks supported on the outer two main bearing journals.
NOTE: Check crankshaft journals for out-of-round before checking for runout, or an out-of-round condition on the center journal can be
confused for an excess runout condition.
2. Set up Dial Indicator with Bracketry TOOL-4201-C or equivalent to measure runout on center main bearing journal.
3. Zero dial indicator.
4. Slowly rotate crankshaft one revolution, recording highest and lowest readings.
5. Crankshaft runout should not exceed 0.03 mm (0.0012 in.). If crankshaft runout is excessive, replace crankshaft.
