positioned on the valve stems
10. Tighten each bolt in two steps to ensure that the
rockers do not bind on the valves.
NOTE: wipe off the excess of liquid gasket from
No. 1 and No. 6 camshaft holder with a shop towel

lnstall the back cover.
Install keys into camshaft grooves.
NOTE: To set the camshafts at TDC position for No.
1 piston, align the holes in the camshafts with the
holes in No. 1 camshsft holders snd insert 5.0 mm
pin punches in the holes.

Install the timing belt (see page 6-12).
Adjust the valve clearance (see page 6-3).
lnstall the rubber seal in the groove of the cylinderhead cover. Seat the seal in the recesses for thecamshaft first, then work it into the groove aroundthe outside edges.
NOTE:
. Before installing the rubber seal, thoroughlyclean the seal and the groove.
. When installing, make sure the seal is seatedsecurely in the corners of the recesses with nogap.
RUEBER SEAL
18.Apply liquid gasket to the rubber seal at the eightcorners of the recesses.
NOTE:
. Use liquid gasket, Part No. 08718 - OO01 or 08718- 0003.
. Check that the mating surfaces are clean and drybefore applying liquid gasket.. Do not installthe parts if 5 minutes or more naveelapsed since applying liquid gasket. Instead,reapply liquid gasket after removing old residue.. After assembly, wait at least 30 minutes beforefilling the engine with oil.
Apply liquid gasket tothe shaded areas.

19. When installing the cylinder head cover. hold the
rubber seal in the groove by placing your fingers on
the camshaft holder contacting surfaces (top of the
semicircles).
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and iorth to seat
the rubber seal.
NOTE:
. Before installing the cylinder head cover, clean
the cylinder head contacting surfaces using a
shop towel.
. Do not touch the parts where liquid gasket was
applied.

Tighten the nuts in 2 or 3 steps. In the final step,
tighten ali nuts, in sequence, to 9.8 N'm (1.0 kgim,
7.2 tbf.ft).
After installing, check that all tubes, hoses and con-
nectors are installed correctly.

9. Remove the upper bearing halves from connectingrods and set them aside with their respective caps.
10. Reinstall main caps and bearings on the engine inproper order.
11. lf you can feel a ridge oI metal or hard carbonaround the top of each cylinder, remove it with afldge reamer.
Follow the reamer manufacturer's instructions.
CAUTIONT lf the ridge is not lemoved, it may dam-age the pistons as they are pushed out.

Removal (cont'dl
Use the wooden handle ot a hammer to drive the
pistons out.
CAUTION:
. Take care not to damage the contact surface ot
the metal gasket.
. When removing the piston/connecting rod, take
care not to hit the oil iet (818C1, 818C5 enginesl.
. ll the oil iet nozzle is damaged or bent, replace
the oil iet assembly {818C1, B18C5 engincs.
page 8-9).
Reinstall the rod bearings and caps after removing
each piston/connecting rod assembly.
l\4ark each piston/connecting rod assembly with its
cylinder number to avoid mixup on reassembly.
NOTE; The existing number on the connecting rod
does not indicate its position in the engine, it indi-
cates the rod bore size.
End Play
NOTE: End play should be inspected before removing
crankshaft.
Push the crank firmly away from the dial indicator, and
zero the dial against the end of the crank. Then pull the
crank firmly back toward the indicator; dial reading
should not exceed service limit.
Crankshaft End Play:
Standard (New): 0.10 - 0.35 mm
{0.00'l - 0.014 inl
Service Limit: 0.45 mm 10.018 inl
. lf end play is excessive, inspect the thrust washers
and thrust surface on the crankshaft. Replace parts as
necessary.
NOTE:
. Thrust washer thickness is tixed and must not be
changed either by grinding or shimming.
. Thrust washers are installed with grooved sides fac-
ing outward.

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)
15 mm{0.6 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.
