Runout

NOTE: Crankshaft main bearing journals must be within specifications before checking runout.






1. Use Dial Indicator With Bracketry to measure the crankshaft runout.
- Rotate the crankshaft and subtract the lowest dial indicator reading from the highest dial indicator reading to figure the crankshaft runout. If it is out of specification, replace as necessary.
