'1. Set the crankshaft to BDC for each cylinder.
2, Remove the connecting rod caps, and slip short sec-
tions of rubber hose over the threaded ends of the
connecting rod bolts.
3. Install the ring compressor, and check that the bear-
ing is securely in place.
4. Position the arrow facing the timing belt side of the
eng ine.
The arrow must facethe timing belt sideot the engine. Theconnecting rod oil holemust face the intakemanjfold (81881 engine).

Position the piston in the cylinder. and tap it in
using the wooden handle of a hammer.
NOTE; Maintain downward force on the ring com-pressor to prevent rings from expanding before
entering the cylinder bore.
6. Stop after the ring compfessor pops free, and check
the connecting rod-to-crank journal alignment
betore pushing piston in to place,
7.Check the connecting rod bearing clearance withplastigage {see page 7-9).
Apply engine oil to the bolt threads. then install the
rod caps with bearings,
Installthe nuts, and toroue it.

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.

E engine oilto the main bearings and rod bearings.
1. lnstall the thrust washers in the No. 4 iournal of the
cylinder block.

Insert bearing halves in the engine block and con-
necflng roos.

Rotate the crankshaft clockwise, put journals into
connecting rods No. 1 and No.4, and install the rod
caps and nuts tinger-tight.
NOTEI lnstall caps so the bearing recess is on the
same side as the recess in the rod.
Check rod bearing clearance with plastigage (see
page 7-9), then tighten the capnuts in 2 steps.

818C1, 818C5 engines:
CAUTION: Whenever any crankshaft o. connecting rod
bearing is replaced, it is necessary after reassembly to
run the engine at idling speed until it reaches normal
opelating temperature, then continue to run it tor
approximalely 15 minutes.
Apply non-hardening liquid gasket to the block mat-
ing surface of the right side cover, and install it on
the cylinder block.
NOTEI
. Use liquid gasket, Part No. 08718 - 0001 or 08718- 0003,
. Check that the mating surfaces are clean and dry
before applying liquid gasket.
. Apply liquid gasket as an even bead, centered
between the edges of the mating surface.
. To prevent leakage of oil, apply liquid gasket to
the inner threads of the bolt holes.
. Do not install the parts if 5 minutes or more have
elapsed since applying the liquid gasket. Instead,
reapply liquid gasket after removing the old
residue.
After assembly, wait at least 30 minutes betore
filling the engine with oil.
RIGHT SIDE COVER:
Apply liquid gasket alongthe broken line.

OIL FILTER WRENCH
8-8
Eight numbers (1 to 8) are printed on the surlace ol
the filter.
The lollowing explains the procedure for tightening
filters using these numbers.
1) Make a mark on the engine oil cooler (818c5
engine) or cylinder block (8188'1, 818C1 engines)
under the number that shows at the bottom of
the filter when the rubber seal is seated.
2) Tighten the filter by turning it clockwise seven
numbers Irom the marked point. For example, if a
mark is made under the number 2 when the rub
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point

5. After installation, fill the engine with oil up to the
specilied level, run the engine for more than 3 min-
utes, then check for oil leakage and oil level.
CAUTION: Installation using other than the above
procedure could result in serious engine damage
duo to oil leakage.
