while prying the crankshaft back and forth with a
screwdriver.
Standard thrust clearance:
0.020 ± 0.220 mm (0.0008 ± 0.0087 in.)
Maximum thrust clearance:
0.30 mm l0.0118 in.)
If the thrust clearance is greater than maximum, re±
place the thrust washers as a set.

2.440 ± 2.490 mm 10.0961 ± 0.0980 in.)
(b) Using the removed main bearing cap bolts, pry the
main bearing cap back and forth, and remove the main
bearing caps, lower bearings and lower thrust wash±
ers (No.3 main bearing cap only).
HINT:
wKeep the lower bearing and main bearing cap
together.
wArrange the main bearing caps and lower thrust
washers in correct order. HINT:
wKeep the bearings, connecting rod and cap to±
gether.
wArrange the piston and connecting rod assembl±
ies in correct order.
9. REMOVE MAIN BEARING CAPS AND CHECK OIL
CLEARANCE
(a) Uniformly loosen and remove the main bearing cap
bolts in several passes, in the sequence shown.

(d) Clean each main journal and bearing.
(e) Check each main journal and bearing for pitting and
scratches.
If the journal or bearing is damaged, replace the bear±
ings. If necessary, grind or replace the crankshaft. (c) Lift out the crankshaft.
HINT: Keep the upper bearing and upper thrust wash±
ers together with the cylinder block.
(h) Install the main bearing caps.
(See step 4 on page EG1±121)
Torque: 59 N±m (600 kgf±cm, 43 ft±lbf)
NOTICE: Do not turn the crankshaft.
(i) Remove the main bearing caps.
(See procedure (a) and (b) on the previous page) (f) Place the crankshaft on the cylinder block.
(g) Lay a strip of Plastigage across each journal.

CYLINDER BLOCK INSPECTION
1. CLEAN CYLINDER BLOCK
A. Remove gasket material
Using a gasket scraper, remove all the gasket material
from the top surface of the cylinder block.
B. Clean cylinder block
Using a soft brush and solvent, thoroughly clean the
cylinder block.
2. INSPECT TOP SURFACE OF CYLINDER BLOCK FOR
FLATNESS
Using a precision straight edge and thickness gauge,
measure the surfaces contacting the cylinder head
gasket for warpage.
Maximum warpage:
0.05 mm (0.0020 In.)
If warpage is greater than maximum, replace the cylin±
der block.
3. INSPECT CYLINDER FOR VERTICAL SCRATCHES
Visually check the cylinder for vertical scratches.
If deep scratches are present, rebore all the 4 cylin±
ders. If necessary, replace the cylinder block.HINT: Arrange the main bearing caps, bearings and
thrust washers in correct order.

PISTON AND CONNECTING ROD ASSY
DISASSEMBLY
1. CHECK FIT BETWEEN PISTON AND PISTON PIN
Try to move the piston back and forth on the piston
pin.
If any movement is felt, replace the piston and pin as
a set.
2. REMOVE PISTON RINGS
(a) Using a piston ring expander, remove the 2 compres±
sion rings.
3. DISCONNECT CONNECTING ROD FROM PISTON
(a) Using a small screwdriver, pry out the 2 snap rings.(b) Remove the 2 side rails and oil ring by hand.
HINT: Arrange the rings in correct order only.
(b) Gradually heat the piston to 80±90
C (176±194
F).

3. INSPECT CONNECTING ROD
A. Inspect connecting rod alignment
Using a rod aligner and thickness gauge, check the
connecting rod alignment.
wCheck for bend.
Maximum bend:
0.05 mm (0.0020 in.) per 100 mm (3.94 In.)
If bend is greater than maximum, replace the connect±
ing rod assembly.
wCheck for twist
Maximum twist:
0.15 mm (0.0059 in.) per 100 mm (3.94 in.)
If twist is greater than maximum, replace the connect±
ing rod assembly.
B. Inspect piston pin oil clearance
(a) Using a caliper gauge, measure the inside diameter of
the connecting rod bushing.
Bushing inside diameter:
22.005 ± 22.017 mm (0.8663 ± 0.8668 in.) D. Inspect±piston pin fit
At 60
C (140
F), you should be able to push the
piston pin into the piston pin hole with your thumb.
(b) Using a micrometer, measure the piston pin diameter.
Piston pin diameter:
21.997 ± 22.009 mm (0.8660 ± 0.8865 in.)
± 5S±FE ENGINEENGINE MECHANICALEG1±111

(c) Subtract the piston pin diameter measurement from
the bushing inside diameter measurement.
Standard oil clearance:
0.005 ± 0.011 mm (0.0002 ± 0.0004 in.)
Maximum oil clearance:
0.05 mm (0.0020 In.)
If the oil clearance is greater than maximum, replace
the bushing. If necessary, replace the piston and
piston pin as a set.
(b) Align the oil holes of a new bushing and the connect±
ing rod.
(c) Using SST and a press, press in the bushing.
SST 09222±30010
(e) Check the piston pin fit at normal room temperature.
Coat the piston pin with engine oil, and push it into the
connecting rod with your thumb. (d) Using a pin hole grinder, hone the bushing to obtain
the standard specified clearance (see step B above)
between the bushing and piston pin. C. If necessary, replace connecting rod bushing
(a) Using SST and a press, press out the bushing.
SST 09222 ± 30010
± 5S±FE ENGINEENGINE MECHANICALEG1±112

(b) If the cap nut cannot be turned easily, measure the
outside diameter of the connecting rod bolt with a
vernier caliper.
Standard outside diameter:
7.860±8.000 mm (0.3094±0.3150 in.)
Minimum outside diameter:
7.60 mm (0.2992 in.)
HINT: If the location of this area cannot be judged by
visual inspection, measure the outer diameter at the
location shown in the illustration.
If the outside diameter is less than minimum, replace
the connecting rod bolt and nut as a set. D. Inspect connecting rod bolts
(a) Install the cap nut to the connecting rod bolt. Check
that the cap nut can be turned easily by hand to the
end of the thread.
