Figure 3-69. Inspecting Cylinder Block.
If the cylinder block assembly is acceptable for reuse in all other respects, several
passes of the block over 500 grit emery paper on a lap table, is recommended to put the block face in
a like-new condition. If circular wear patterns can be felt with the fingernail, grind the running face as
necessary to remove the wear pattern keeping the face parallel to the original face. Lap the reworked
face on 500 grit emery as described above to remove the mat finish. Clean the block thoroughly in a
commercial degreaser such as trichloroethylene and blow dry with compressed air. Check tolerance of
refinished block as outlined in figure 3-70. If reworked block does not meet the tolerances, discard block.
