CYLINDER BLOCK - CONTINUED
CLEANING/INSPECTION - CONTINUED
If cylinder sleeves are to be reused, they must be installed in their original location for
checking cylinder sleeve protrusion. If one or more cylinder sleeves were discarded, a
new cylinder sleeve must be substituted. After cylinder sleeve protrusion is adjusted,
the shims and spacers used for adjustment must be kept with that cylinder sleeve and
shims, spacers, and cylinder sleeves must be tagged for their respective location in
cylinder block for assembly.

The thinnest shim available is 0.007 inch (0.18 mm), therefore it may be necessary to
use a combination of counterbore cutting and adding shims or spacers to achieve the
correct protrusion of 0.003 to 0.006 inch (0.08 to 0.15 mm).
If material to be removed during counterbore cutting will result in counterbore depth
exceeding 0.412 inch (10.46 mm), cylinder block cannot be reused, unless a salvage
sleeve can be installed, steps 57 thru 63.
