Cylinder Bore Honing

1. Measure the cylinder bores (see step 4 on page 7-
16). If the cylinder block is to be reused, hone the
cylinders and remeasure the bores. Scored or
scratched cylinder bores must be honed.
2. Hone the cylinder bores with honing oil and a fine
(400 grit) stone in a 60 degree crosshatch pattern.
NOTE:
• Use only a rigid hone with 400 grit or finer stone,
such as Sunnen, Ammco, or equivalent.
• Do not use stones that are worn or broken.
3. When honing is complete, thoroughly clean the
cylinder block of all metal particles. Wash the
cylinder bores with hot soapy water, then dry and
oil them immediately to prevent rusting. Never use
solvent, it will only redistribute the grit on the
cylinder walls.
4. If scoring or scratches are still present in the
cylinder bores after honing to the service limit,
rebore the cylinder block. Some light vertical
scoring and scratching is acceptable if it is not deep
enough to catch your fingernail and does not run
the full length of the bore.
