3. Check the cylinder head for warpage using a machinist
straight edge and the thickness gauge set (Part No. 353-
72251-0). lf warpage exceeds 0.004 in [0.10 mm], replace the
cylinder head.
4. Using an accurate dial indicator, measure the crankshaft
deflection with the upper and lower main bearings installed.
Measure as follows:
• Support both ends of the crankshaft at the main bearings in
precision V-blocks or an alignment jig.
• Slowly rotate crankshaft and record measurement at each
crankshaft bearing
(1)
and at both ends of the crankshaft.
If deflection is more than 0.002 in [0.05 mm], replace the
crankshaft.
5. Measure and record the following crankshaft dimensions and
check for signs of wear:
• Dimension 1 : Distance between the outside edges of each
pair of cranks haft webs. Measure at both ends of the webs.
• Dimension 2: Distance between each pair of crankshaft
webs.
• Dimension 3: Distance between the outside edges of the
first and last crankshaft webs.
