under the heads of the main bearings cap bolts.
(2) Install and uniformly tighten the 14 bolts of the main
bearing caps, in several passes, in the sequence
shown.

If any one of the main bearing cap bolts does not meet the
torque specification, replace the main bearing cap bolt.
(3) Mark the front of the main bearing cap bolt withpaint.
(4) Retighten the main bearing cap bolts by 90 ° in the
numerical order shown above.
(5) Check that the painted mark is now at a 90° angle
to the front.
(c) Check that the crankshaft turns smoothly.
(d) Check that the crankshaft thrust clearance (See page EM−83 ).
10. INSTALL PISTON AND CONNECTING ROD AS- SEMBLIES
(a) Cover the connecting rod bolts with a short piece of hose

(b) Using a piston ring compressor, push the correctly num-
bered piston and connecting rod assemblies into each
cylinder with the front mark of the piston facing forward.
11. INSTALL CONNECTING ROD CAP
(a) Place the connecting rod cap on the connecting rod. (1) Match the numbered connecting rod cap with theconnecting rod.
(2) Install the connecting rod cap with the front mark facing for ward.
(b) Install the connecting rod cap nuts.
HINT:
The connecting rod cap nuts are tightened in 2 progres-
sive steps (steps (b) and (d)).
If any connecting rod bolt is broken or deformed, replace
it.
(1) Apply a light coat of engine oil on the threads and under the nuts of the connecting rod cap.
(2) Install and alternately tighten the nuts of the con-
necting rod cap in several passes.
Torque: 48 N·m (490 kgf·cm, 35 ft·lbf)
If any one of the connecting rod cap nuts does not meet the
torque specification, replace the connecting rod bolt and cap
nut as a set.
(3) Mark the front of the connecting rod cap nut and bolt
with paint.
(4) Retighten the connecting rod cap nuts 90 ° as
shown.

(5) Check that the painted mark on the nut is at 90 °
angle in relation to the mark on the bolt.
(c) Check that the crankshaft turns smoothly.
(d) Check that the connecting rod thrust clearance (See page
EM−83 ).
12. INSTALL REAR OIL SEAL RETAINER
(a) Remove any old packing (FIPG) material and be careful not to drop any oil on the contact surfaces of the retainer
and cylinder block.
Using a razor blade and gasket scraper, remove all
the old packing (FIPG) material from the gasket sur-
faces and sealing groove.
Thoroughly clean all components to remove all the
loose material.
Using a non −residue solvent, clean both sealing
surfaces.
(b) Apply seal packing to the retainer as shown in the illustra-
tion.
Seal packing: Part No. 08826−00080 or equivalent
Install a nozzle that has been cut to a 2 − 3 mm (0.08
− 0.12 in.) opening.
HINT:
Avoid applying an excessive amount to the surface.
Parts must be assembled within 5 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.
Immediately remove nozzle from the tube and rein-
stall cap.
(c) Install the retainer with the 4 bolts. Torque: 21 N·m (210 kgf·cm, 15 ft·lbf)
13. INSTALL OIL COOLER COVER AND OIL COOLER
Install a new gasket, the oil cooler cover and oil cooler with the
10 bolts and 2 nuts. Torque: 21 N·m (210 kgf·cm, 15 ft·lbf)

ON−VEHICLE INSPECTION
1. CHECK THAT SPARK OCCURS
(a) Disconnect the high −tension cords (from the ignition coil)
from the distributor cap.
(b) Hold the end approx. 12.5 mm (0.50 in.) from the body ground.
(c) Check if spark occurs while engine is being cranked.
