Cylinder Honing - Honda Civic 2002-2003 Service Manual

• Cylinder Honing
•
•
Only a scored or scratched cylinder bore should be
honed.
1. Measure the cylinder bores (see page 7-151.
If the block is to be reused, hone the cylinders and
remeasure the bores.
2. Hone the cylinder bores with honing oil and a fine
(400 gritl stone in a 60 degree cross-hatch pattern
(A). 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
engine 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.
