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: 0.160 ± 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 crank-
shaft.
3. REMOVE CONNECTING ROD CAPS AND CHECK OIL
CLEARANCE
(a) Using a punch or numbering stamp, place the match±
marks on the connecting rod and cap to ensure correct
reassembly.
(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.

(i) Remove the connecting rod cap.
(j) Measure the Plastigage at widest point.
Standard oil clearance:
STD 0.024 ± 0.055 mm
(0.0009 ± 0.0022 in.)
U/S 0.25 0.023 ± 0.069 mm
(0.0009 ± 0.0027 in.)

If the oil clearance is greater than maximum, replace
the bearings. If necessary, replace the crankshaft. (e) Clean crank pin and bearing.
(f) Check the crank pin and bearing for pitting and
scratches.
If the crank pin or bearing are damaged, replace the
bearings.
If necessary, replace the crankshaft.
(h) Install the connecting rod cap.
(See step 6 on page EM±129)
Torque: 500 kg±cm (36 ft±lb. 49 N±m)
HINT: 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
º1º, º2' and ª3º accordingly.
(Reference)
Standard sized bearing thickness (at center wall):
Mark º1 º 1.484 ± 1.488 mm
(0.0584 ± 0.0586 in.)

Maximum oil clearance: 0.08 mm (0.0031 in.)
HINT: If replacing the cylinder block subassembly, the
bearing standard clearance will be:
No. 3 0.027 ± 0.054 mm
(0.0011 0.0021 in.)
Others 0.017 0.044 mm
(0.0007 ± 0.0017 in.)
If the oil clearance is greater than maximum, replace the
bearings, if necessary, replace the crankshaft.(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 wash-
ers in correct order.
(c) Lift out the crankshaft.
HINT: Keep the upper bearing and upper thrust washers
together with the cylinder block.
