2. CHECK CONNECTING ROD THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while
moving the connecting rod back and forth.
Standard thrust clearance: 0.150 ± 0.330 mm
(0.0059 ± 0.0130 in.)
Maximum thrust clearance: 0.38 mm (0.0150 in.)
If the thrust clearance is greater than maximum, replace the
connecting rod assembly. If necessary, replace the crank-
shaft.
3. REMOVE CONNECTING ROD CAPS AND CHECK OIL
CLEARANCE
(a) Using a punch or numbering stamp, place the rnatchmarks
on the connecting rod and cap to ensure correct reas-
sembly.
(c) Using a plastic±faced hammer, lightly tap the connect-
ing rod bolts and lift off the connecting rod cap.
HINT: Keep the lower bearing inserted with the connect-
ing cap.

1. REMOVE REAR OIL SEAL RETAINER
Remove the six bolts and retainer.
(b) Using SST, remove the connecting rod cap nuts.
SST 09011±38121

(i) Remove the connecting rod cap.
(j) Measure the Plastigage at widest point.
Standard oil clearance:
STD 0.028 ± 0.065 mm
(0.0011 ± 0.0026 in.)
U/S 0.25 0.027 ± 0.080 mm
(0.0011 ± 0.0031 in.)
Maximum oil clearance: 0.08 mm (0.0031 in.)
If the oil clearance is greater than maximum, replace
the bearings. If necessary, grind or replace the crank-
shaft. (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 bearing.
If necessary, grind or replace the crankshaft.
(h) Install the connecting rod cap.
(See step 6 on page EM±165)
Torque: 1st 250 kg±cm (18 ft±ib, 25 N±m)

NOTICE: Do not turn the crankshaft
(d) Cover the connecting rod bolts with a short piece of
hose to protect the crankshaft from damage.
(g) Lay a strip of Plastigage across the crank pin.

HINT: If using a standard bearing, replace with one having
the same number marked on the connecting rod cap. There
are three sizes of standard bearings, marked
º1 º, º2º and º3º accordingly.
(Reference)
Standard sized bearing center wail thickness:
Mark º1º 1.484 ± 1.488 mm
(0.0584 ± 0.0586 in.)
Mark º2º 1.488 ± 1.492 mm
(0.0586 ± 0.0587 in.)
Mark º3º 1.492 ± 1.496 mm
(0.0587 ± 0.0589 in.)
(k) Completely remove the Plastigage.
4. REMOVE PISTON AND CONNECTING ROD
ASSEMBLIES
(a) Remove the all carbon from the piston ring ridge.
(b)Cover the connecting rod bolts.
(See page EM±145)
(c) Push the piston, connecting rod assembly and upper bear-
ing through the top of the cylinder block.
5. CHECK CRANKSHAFT THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while pry-
ing 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 (0.0118 in.)
If the thrust clearance is greater than maximum, replace the
thrust washers as a set.
Thrust washer thickness (STD size only):
2.440 ± 2.490 mm (0.0961 ± 0.0980 in.)
6. REMOVE MAIN BEARING CAP AND CHECK OIL
CLEARANCE
(a) Uniformly loosen and remove the main bearing cap
bolts in several passes in the sequence shown.HINT:
wKeep the bearing, connecting rod and cap together.
wArrange the piston and connecting rod assemblies in
correct order.
