24. INSTALL CONNECTING ROD SMALL END BUSH
(a) Align the oil holes of a new bush and the connecting rod.
(b) Using SST and a press, press in the bushing.
SST 09222-30010
(c) Using a pin hole grinder, hone the bush to obtain the stan-
dard specified clearance between the bush and piston
pin.
Standard oil clearance:
0.005 to 0.011 mm (0.0002 to 0.0004 in.)
(d) Check the piston pin fit at normal room temperature. Coat
the piston pin with engine oil, then push it into the con-
necting rod with your thumb.
25. INSPECT RING GROOVE CLEARANCE
(a) Using a feeler gauge, measure the clearance between
the new piston ring and wall of the ring groove.
Ring groove clearance:
0.03 to 0.08 mm (0.0012 to 0.0031 in.) for No. 1 ring
0.02 to 0.06 mm (0.0008 to 0.0024 in.) for No. 2 ring
0.03 to 0.11 mm (0.0012 to 0.0043 in.) for oil ring
If the groove clearance is not as specified, replace the piston
ring.

26. INSPECT PISTON RING END GAP
(a) Using a piston, push the piston ring which it is a little below
the bottom of the ring travel, where is 110 mm (4.33 in.)
from the top of the cylinder block.
(b) Using a feeler gauge, measure the end gap.
Standard end gap:
0.30 to 0.40 mm (0.0118 to 0.0157 in.) for No. 1 ring
0.50 to 0.60 mm (0.0197 to 0.0236 in.) for No. 2 ring
0.15 to 0.40 mm (0.0059 to 0.0157 in.) for oil (side rail)
ring
Maximum end gap:
0.95 mm (0.0374 in.) for No. 1 ring
1.05 mm (0.0413 in.) for No. 2 ring
1.00 mm (0.0394 in.) for oil (side rail) ring
If the end gap is greater than maximum, replace the
piston ring.
If the end gap is greater than maximum, even with
a new piston ring, replace the cylinder block.
27. INSPECT CONNECTING ROD BOLT
(a) Using vernier calipers, measure the tension portion diam-
eter of the bolt.
Standard diameter: 7.2 to 7.3 mm (0.283 to 0.287 in.)
Minimum diameter: 7.0 mm (0.276 in.)
If the diameter is less than minimum, replace the bolt.
28. INSPECT CRANKSHAFT BEARING CAP SET BOLT
(a) Using vernier calipers, measure the tension portion diam-
eter of the bolt.
Standard diameter: 7.5 to 7.6 mm (0.295 to 0.299 in.)
Minimum diameter: 7.2 mm (0.283 in.)
If the diameter is less than minimum, replace the bolt.

29. INSPECT CRANKSHAFT
(a) Using a dial indicator and V-blocks, measure the circle
runout as shown in the illustration.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
(b) Using a micrometer, measure the diameter of each main
journal.
Diameter: 60.988 to 61.000 mm (2.4011 to 2.4016 in.)
If the diameter is not as specified, check the crankshaft oil clear-
ance
(c) Check each main journal for taper and out-of-round as
shown.
Maximum taper and out-of-round:
0.02 mm (0.0008 in.)
If the taper and out-of-round is greater than maximum, replace
the crankshaft.
(d) Using a micrometer, measure the diameter of each crank
pin.
Diameter: 52.992 to 53.000 mm (2.0863 to 2.0866 in.)
If the diameter is not as specified, check the connecting rod oil
clearance.
(e) Check each crank pin for taper and out-of-round as
shown.
Maximum taper and out-of-round:
0.02 mm (0.0008 in.)
If the taper and out-of-round is greater than maximum, replace
the crankshaft.
30. INSPECT CRANKSHAFT OIL CLEARANCE
HINT:
Crankshaft bearings come in widths of 22.4 mm (0.882 in.) and
19.0 mm (0.748 in.). Install the 22.4 mm (0.882 in.) bearings in
the No. 1 and No. 4 cylinder block journal positions with the
bearing caps. Install the 19.0 mm (0.748 in.) bearings in the No.
2 and No. 3 positions.
(a) Clean each main journal and bearing.

(b) Align the key of the bearing with the keyway of the cylinder
block, then push in the 4 upper bearings.
NOTICE:
Do not apply engine oil to the bearing and its contact sur-
face.
(c) Align the key of the bearing with the keyway of the bearing
cap, then push in the 4 lower bearings.
NOTICE:
Do not apply engine oil to the bearing and its contact sur-
face.
HINT:
A number is marked on each bearing cap to indicate the instal-
lation position.
(d) Place the crankshaft on the cylinder block.
(e) Lay a strip of Plastigage across each journal.
(f) Examine the front marks and numbers, then install the
bearing caps on the cylinder block.
(g) Apply a light coat of engine oil to the threads of the bear-
ing cap bolts.
(h) Temporarily install the 8 bearing cap bolts to the inside
positions.
(i) Install the bearing cap by hand using the inner bolt as a
guide. Stop when the bearing cap is about 6 mm (0.23 in.)
away from contact with the cylinder block.

(s) If replacing a bearing, replace it with one having the same
number. If the number of the bearing cannot be deter-
mined, select the correct bearing by adding together the
numbers imprinted on the cylinder block and crankshaft,
then refer to the table below for the appropriate bearing
number. The No. 1 and No. 2 journal bearing come in 5
sizes, marked º3º, º4º, º5º, º6º and º7º. The No. 3 and No.
4 journal bearings come in 5 standard bearing sizes,
