4. INSPECT PISTON AND CONNECTING ROD
(a) Inspect the piston oil clearance.
HINT:
There are 3 sizes of the standard piston diameter, marked º1º,
º2º and º3º accordingly. The mark is stamped on the piston top.
(1) Using a micrometer, measure the piston diameter at
right angles to the piston pin center line, 20.5 mm
(0.807 in.) from the piston head.
Piston diameter:
STD Mark º1º
Mark º2º
Mark º3º86.815 ± 86.825 mm (3.4179 ± 3.4183 in.)
86.825 ± 86.835 mm (3.4183 ± 3.4186 in.)
86.835 ± 86.845 mm (3.4186 ± 3.4190 in.)
O/S 0.5087.315 ± 87.345 mm (3.4375 ± 3.4387 in.)
(2) Measure the cylinder bore diameter in the thrust
directions. (See step 2)
(3) Subtract the piston diameter measurement from the
cylinder bore diameter measurement.
Standard oil clearance:
0.175 ± 0.195 mm (0.0068 ± 0.0076 in.)
Maximum oil clearance: 0.215 mm (0.0085 in.)
If the oil clearance is greater than maximum, replace all the 4
pistons and rebore all the 4 cylinders. (See page EM±104) If
necessary, replace the cylinder block.

Using a feeler gauge, measure the clearance between
new piston ring and the wall of the ring groove.
Ring groove clearance (No.1, No.2):
0.030 ± 0.070 mm (0.0012 ± 0.0028 in.)
If the clearance is not as specified, replace the piston.
(c) Inspect the piston ring end gap.

(2) Using a piston, push the piston ring a little beyond
the bottom of the ring travel, 110 mm (4.33 in.) from
the top of the cylinder block.
(3) Using a feeler gauge, measure the end gap.
Standard end gap:
No.10.270 ± 0.490 mm (0.0106 ± 0.0192 in.)
No.20.450 ± 0.670 mm (0.0177 ± 0.0263 in.)

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, rebore all the 4 cylinders (see page EM±104) or replace
the cylinder block.
(d) Inspect the 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.
(e) Using a rod aligner and feeler gauge, check the connect-
ing rod alignment.
(1) Check for bend.
Maximum bend:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If bend is greater than maximum, replace the connecting rod as-
sembly.
(2) Check for twist
Maximum twist:
0.15 mm (0.0059 in.) per 100 mm (3.94 in.)
If twist is greater than maximum, replace the connecting rod as-
sembly.
(f) Inspect the piston pin oil clearance.

of the connecting rod bushing.
Bushing inside diameter:
22.005 ± 22.017 mm (0.8663 ± 0.8668 in.)

(2) Using a micrometer, measure the piston pin diame-
ter.
Piston pin diameter:
21.997 ± 22.009 mm (0.8660 ± 0.8665 in.)
(3) 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 bush-
ing. (See page EM±104) If necessary, replace the piston and
piston pin as a set.
(g) Inspect the connecting rod bolts.
(1) 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.
(2) If the cap nut cannot be turned easily, measure the
outside diameter of the connecting rod bolt with a
vernier caliper.
Standard diameter:
7.860 ± 8.000 mm (0.3094 ± 0.3150 in.)
Minimum 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 illustra-
tion.
If the outside diameter is less than minimum, replace the con-
necting rod bolt and nut as a set.

(1) Place the crankshaft on V±blocks.
(2) Using a dial indicator, measure the circle runout at
the center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
(b) Inspect the main journals and crank pins.
(1) Using a micrometer, measure the diameter of each
main journal and crank pin.
Main journal diameter:
STD54.988 ± 55.003 mm (2.1653 ± 2.1655 in.)
U/S 0.2554.745 ± 54.755 mm (2.1553 ± 2.1557 in.)

U/S 0.2551.745 ± 51.755 mm (2.0372 ± 2.0376 in.)
If the diameter is not as specified, check the oil clearance. (See
page EM±86) If necessary, grind or replace the crankshaft.
(2) Check each main journal and 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.
6. IF NECESSARY, GRIND AND HONE MAIN JOURNALS
AND/OR CRANK PINS
Grind and hone the main journals and/or crank pins to the fin-
ished undersized diameter. (See procedure in step 5) Install
new main journal and/or crankshaft pin undersized bearings.
