(g) Install the connecting rod cap with the 2 bolts.
(See page EM±101)
Torque:
1st: 24.5 N´m (250 kgf´cm, 18 ft´lbf)
2nd: Turn extra 90°
NOTICE:
Do not turn the crankshaft.
(h) Remove the 2 bolts, connecting rod cap and lower bear-
ing. (See steps (b) and (c))
(i) Measure the Plastigage at its widest point.
Standard oil clearance:
0.038 ± 0.064 mm (0.0015 ± 0.0025 in.)
Maximum oil clearance: 0.08 mm (0.0031 in.)
If the oil clearance is greater than maximum, replace the bear-
ings. If necessary, grind or replace the crankshaft.
HINT:
If replacing a bearing, replace it with one having the same num-
ber as marked on the connecting rod. There are 4 sizes of stan-
dard bearings, marked º1º, º2º, º3º and º4º accordingly.
Reference:
Standard bearing center wall thickness:
Markmm (in.)

º4º1.493 ± 1.496 (0.0588 ± 0.0589)
(j) Completely remove the Plastigage.
25. REMOVE PISTON AND CONNECTING ROD
ASSEMBLIES
(a) Using a ridge reamer, remove all the carbon from the top
of the cylinder.
(b) Push the piston, connecting rod assembly and upper
bearing through the top of the cylinder block.
HINT:
Keep the bearings, connecting rod and cap together.
Arrange the piston and connecting rod assemblies in the
correct order.

26. CHECK CRANKSHAFT THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while prying
the crankshaft back and forth with a screwdriver.
Standard thrust clearance:
0.04 ± 0.24 mm (0.0016 ± 0.0095 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:
1.930 ± 1.980 mm (0.0760 ± 0.0780 in.)
27. REMOVE MAIN BEARING CAPS AND CHECK OIL
CLEARANCE
(a) Uniformly loosen and remove the 8 main bearing cap
bolts and seal washers, in the several passes, in the se-
quence shown.
(b) Uniformly loosen and remove the 16 main bearing cap
bolts, in several passes, in the sequence shown.
(c) Using a screwdriver, pry out main bearing caps. Remove
the 4 main bearing caps, lower bearings and (No.2 main
bearing cap only) 2 lower thrust washers.
NOTICE:
Pull up the main bearing cap little by little to the right and
the left by turns and pay attention not to damage the joint
surface of the cylinder block and the main bearing cap.
HINT:
Keep the lower bearing and main bearing cap together.
Arrange the main bearing caps and lower thrust washers
in correct order.
