Crankshaft End Play
1. Measure the crankshaft end play. Use the Dial
Indicator with Bracketry to measure crankshaft end
play.
2. Position the crankshaft to the rear of the cylinder
block.
3. Zero the Dial Indicator with Bracketry.
4. Move the crankshaft to the front of the cylinder block.
Note and record the camshaft end play.
• If camshaft end play exceeds specifications, re-
place the crankshaft thrust washers or thrust
bearing.
Crankshaft Runout
NOTE: Crankshaft main bearing journals must be within
specifications before checking runout.
Use the 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.
Cylinder Bore Taper
Measure the cylinder bore at the top and bottom. Verify
the cylinder bore is within the wear limit. The difference
indicates the cylinder bore taper. Bore the cylinder to
the next oversize.
