13. REMOVE ENGINE BALANCER
(a) Uniformly loosen and remove the 6 bolts in several
passes, in the sequence shown.
(b) Remove the engine balancer and spacers.
14. CHECK CONNECTING ROD THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while mov-
ing the connecting rod back and forth.
Standard thrust clearance:
0.160 ± 0.312 mm (0.0063 ± 0.0123 in.)
Maximum thrust clearance: 0.35 mm (0.0138 in.)
If the thrust clearance is greater than maximum, replace the
connecting rod assembly. If necessary, replace the crankshaft.
15. REMOVE CONNECTING ROD CAPS AND CHECK OIL
CLEARANCE
(a) Check the matchmarks on the connecting rod and cap to
ensure correct reassembly.
(b) Remove the 2 connecting rod cap nuts.
(c) Using a plastic±faced hammer, lightly tap the connecting
rod bolts and lift off the connecting rod cap.
HINT:
Keep the lower bearing inserted with the connecting rod cap.
(d) Cover the connecting rod bolts with a short piece of hose
to protect the crankshaft from damage.
(e) Clean the crank pin and bearing.
(f) Check the crank pin and bearing for pitting and scratches.
If the crank pin or bearing is damaged, replace the bearings. If
necessary, grind or replace the crankshaft.

necting rod.
(b) Install the connecting rod cap with the front mark facing
forward.
11. INSTALL CONNECTING ROD CAP NUTS
HINT:

(b) and (d)).
If any one of the connecting rod bolts is broken or de-
formed, replace it.
(a) Apply a light coat of engine oil on the threads and under
the nuts of the connecting rod cap.
(b) Install and alternately tighten the 2 cap nuts in several
passes.
Torque: 25 N´m (250 kgf´cm, 18 ft´lbf)
If any one of the cap nuts does not meet the torque specifica-
tion, replace the connecting rod bolt and cap nut as a set.

(3) Using SST (A), press down the valve lifter and place
SST (B) between the camshaft and valve lifter. Re-
move SST (A).
SST 09248±55040 (09248±05410, 09248±05420)
HINT:
Apply SST (B) at a slight angle on the side marked with
º9º or º7º, at the position shown in the illustration.
When SST (B) is inserted too deeply, it will get pinched by
the shim. To prevent it from being stuck, insert it gently
from the intake side, at a slight angle.
Using a small screwdriver and magnetic finger, remove
the adjusting shim.
(b) Determine the replacement adjusting shim size according
to these Formula or Charts:
(1) Using a micrometer, measure the thickness of the
removed shim.
(2) Calculate the thickness of a new shim so the valve
clearance comes within the specified value.
T .......... Thickness of used shim
A .......... Measured valve clearance
N .......... Thickness of new shim
Intake
N = T + (A ± 0.20 mm (0.008 in.))
Exhaust
N = T + (A ± 0.30 mm (0.012 in.))
(3) Select a new shim with a thickness as close as pos-
sible to the calculated values.
HINT:
Shims are available in 17 sizes in increments of 0.050 mm
(0.0020 in.), from 2.500 mm (0.0984 in.) to 3.300 mm (0.1299
in.).

(d) Check the valve overall length.
Standard overall length:
Intake95.45 mm (3.5779 in.)
Exhaust95.40 mm (3.7559 in.)
Minimum overall length:
Intake94.95 mm (3.7382 in.)
Exhaust94.90 mm (3.7362 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder or
replace the valve.
NOTICE:
Do not grind off more than minimum.
11. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:
If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.
If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
Check that the seat contact is in the middle of the
valve face with the following width:
1.0 ± 1.4 mm (0.039 ± 0.055 in.)
If not, correct the valve seats as follows:
(1) If the seating is too high on the valve face, use 30°
and 45° cutters to correct the seat.
