8. If the plastigage measures too wide or too narrow,
remove
the upper half of the bearing, install a new,
complete bearing with the same color code(s), and
recheck the clearance. Do not file, shim, or scrape
the bearings or the caps to adjust clearance.
9. If the plastigage shows the clearance is still
incorrect, try the next larger or smaller bearing (the
color listed
above
or below that one), and check
clearance again.
If
the proper clearance cannot be
obtained by using the appropriate larger or smaller
bearing, replace the crankshaft and start
over.

2. Each rod has a tolerance range from 0-0.024 mm
(0.0009 in.), in 0.006 mm (0.0002 in.) increments,
depending on the size of its big end bore. It's then
stamped with a number or bar (1, 2, 3 or 4/1, II, III, or
1111) indicating the range. You may find any
combination of numbers and bars in any engine.
(Half the number or bar is stamped on the bearing
cap, the other half on the rod.)
If you can't read the code because of an
accumulation of oil and varnish, do not scrub
it
with a wire brush or scraper. Clean
it
only with
solvent or detergent.
