f. Using a plastic-faced hammer and brass bar, lightly tap out the piston and pin. Then remove the
connecting rod.
HINT:
The piston and pin are a matched set.
Be sure to organize the removed pistons, pins, rings, connecting rods and bearings in such a way
that the parts can be reinstalled exactl
y as before.

6.INSPECT CRANKSHAFT THRUST CLEARANCE
a. Using a dial indicator, measure the thrust clearance while prying the crankshaft back and forth with
a screwdriver.

13001b00030057005200030013001100130013001b001a0003[in.) Maximum thrust clearance:
0.30 mm (0.0118 in.)
If the thrust clearance is greater than the maximum, replace the thrust washers as a set.
Thrust washer thickness:
2.440 to 2.490 mm (0.0961 to 0.0980 in.)
7.INSPECT CRANKSHAFT OIL CLEARANCE
a. Remove the 10 crankshaft bearin
g cap bolts.

b. Uniformly loosen and remove the 20 crankshaft bearing cap bolts in the sequence shown in the
illustration.
c. Using 2 screwdrivers, pry out the crankshaft bearing cap, and remove the 5 crankshaft bearing caps,
5 lower bearings and 2 lower thrust washers (No. 3 crankshaft bearing cap only).
HINT:
Keep the lower bearing and bearing cap together.

Be sure to organize the bearing caps and lower thrust washers in such a way that they can be
reinstalled exactly as before.
d. Lift out the crankshaft.
e. Remove the 2 upper thrust washers.
HINT:
Be sure to organize the removed upper thrust washers in such a way that they can be
reinstalled exactl
y as before.

Keep the upper bearings together with the cylinder block.
f. Clean each crankshaft journal and bearing.
g. Check each crankshaft journal and bearing for pitting and scratches.
If the journal or bearing is damaged, replace the bearings. If necessary, replace the crankshaft.
h. Install the 10 crankshaft bearings and 5 crankshaft bearing caps with the 30 bolts (see step 25). Do
not install the crankshaft.
