CAUTION
Do not file, shim, or scrape the bearings or the
caps to adjust clearance.
7) If th e plastigage shows th e clearance is still in-
correct, try the next larger or smaller bearing (the
color listed above or below that one), and check
clearance again.
NOTE
If the proper clearance cannot be obtained by using
the appropriate larger or smaller bearings, replace the
crankshaft and start over.
CAUTION
If the marks are indecipherable because of an ac-
