Engine Block
Cylinder Honing
The cylinder liners are made wlth FRM ({iber rein{orced
metal). Hone the cylinders only as described here.
1. Measure the cylinder bores (see step 3 on page 7-
14). lf the engine block is to be reused, hone the
cVlinders and remeasure the bores. Scored or
scratched cylinder bores must be honed.
2. Hone the cylinders using the following equipment,
materials and methods:
. U s e o n l y a r i g i d h o n e .
. Honing stones: GC-600-J or finer stones for
nonferrous metals
. Pressu re: 200 - 300 kPa (2 3 kgf/cm' ,28-43 psi)
. H o n i n g r p m : 4 5 - 5 0
. Honing thickness; Less than 0.02 mm (0.0008 in.)
Do not hone more than 20 cycles,
. Honing lubricant: Oil type
. Honing pattern: 60 degree cross-hatch (A)
. Hone cleaning: Clean the stones every five cycles.
When honing is complete, thoroughly clean the
engine blockof 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.
lf scoring or scratches are still present in the
cylinder bores after honing to the service limit,
rebore the cylinders. Some light vertical scoring
and scratching is acceptable if it is not deep enough
to catch your fingernail and if it does not run the full
length of the bore.
