Bore Honing
l/easure cylinder bores as shown on page 7-14.lf the block is to be reused, hone the cylinders andremeasure the bores.
Hone cylinder bores with honing oil and a fine (400
grat) stone in a 60 degree cross-hatch pattern.
NOTE:
. Use only a rigid hone with 400 grit or finer stonesuch as Sunnen, Ammco, or equivalent.a Do not use stones that are worn or oroKen.
When honing is complete, thoroughly clean thecylinder block of all melal particles. Wash the cylin-der bores with hot soapy water, then dry and oilimmediately to prevent rusting.
NOTE: Never use solvent, it wili only redistribute
the grit on the cylinder walls.
lf scoring or scratches are still present in cylinderbores after honing to the service limit, rebore theengine block.
NOTE: Some light vertical scoring and scratching isacceptable if it is not deep enough to catch your fin-gernail and does not run the full length ofthe bore.
NOTE:
. After honing, clean the cylinder thoroughly withsoapy water.o Only scored or scratched cylinder bores must behoned.

Pistons
Inspection
1. Check the piston lor distortion or cracks.
NOTE: lf the cylinder is bored, an oversized piston
musl be used.
2. Measure the piston diameter at a point 15 mm
(0.6 in) from the bottom of the skrrt.
Piston Diameter:
Standard (Newl: 80.98 - 80.99 mm
(3.188 - 3.189 in)
Service Limit: 80.97 mm (3.188 in)

3. Calculate the difference between cylinder bore
diameter on (see page 7-14) and piston diameter.
Piston-to-Cylinder Clearance:
Standard (Newl: 0.010 - 0.040 mm
(0.0004-00016in)
Service Limit: 0.05 mm (0.002 inl
lf the clearance is near or exceeds the service limit,
inspect the piston and cylinder block for excessive
wear.

Piston Rings
Replacement
Using a ring expander, remove old piston rlngs.
Clean all ring grooves thoroughly.
o Use a squared-ofl broken ring or ring groove
cleaner with blade to fit piston grooves.
. lop ring groove is 1.0 mm (0.039 in) wide, sec
ond groove is 1.2 mm (0.047 in) wide, and oil
ring groove is 2.8 mm (0.110 in) wide.
. File down blade if necessary.
CAUTION: Do not use a wire brush to clean the
ring lands, or cut ring lands deeper with cleaning
tool.
NOTE: lf the piston is to be separated from the con
necting rod, do not install new rings yet.
Install new rings in the proper sequence and posa-
tion (see page 7 21).
Do not use old piston rings.
PISTON RING
End Gap
Using a piston, push a new ring into the cvlinder
bore 15 - 20 mm 10.6 0.8 in) f rom the bottom.
2. N,4easure the piston ring end gap with a feeler
gauge:
lf the gap is too small, check to see if you have
the proper rings for your engine.
. lf the gap is too large, recheck the cylinder bore
diameter against the wear limits on page 7-13.
lf the bore is over the service limit, the cylinder
block must be rebored.

Inspection
Park the vehicle on level ground, and turn ofl the
engine. Allow the oil a few minutes to drain back
into the oil pan so the dipstick will show the actual
tevet,
Make certain that the oil level indicated on the dip-
stick is between the upper and lower marks.
lf the level has dropped close to the lower mark,
add oil until it reaches the upper mark.
CAUTION: Insert the dipstick caretully to avoid
bending it.

Replacement
CAUTION: Remove the drain plug carefully while the
engine is hot; the hot oil may cause scalding.
