8. Using a suitable ridge reamer tool, clean the top of
the cylinder bore; then using a ball hone, hone the
cylinders to produce a 45-55° cross-hatch.
NOTE: To produce the proper 45-55° cross-hatch
pattern, use a low-RPM drill (600 RPM) at the rate
of 25 strokes per minute. Use honing oil or light-
weight petroleum-based oil. Thoroughly clean the
cylinder after honing using soap and hot water.
Dry with compressed air; then immediately apply
engine oil to the cylinder bore. If the bore is
severely scored or out of round, the cylinders must
be bored.

ence of the journal. Journal measurements must be
within specifications.
