1. INSPECT CONNECTING ROD THRUST CLEARANCE
(a) Using a dial indicator, measure the thrust clearance while
moving the connecting rod back and forth.
Standard thrust clearance:
0.160 to 0.362 mm (0.0063 to 0.0143 in.)
Maximum thrust clearance: 0.362 mm (0.0143 in.)
If the thrust clearance is greater than the maximum, replace the
connecting rod assembly(s). If necessary, replace the crank-
shaft.
2. INSPECT CONNECTING ROD OIL CLEARANCE
HINT:
The connecting rod cap bolts are tightened in 2 progressive
steps.
(a) Check that the matchmarks on the connecting rod and
cap are aligned to ensure the correct reassembly.
HINT:
The matchmarks on the connecting rods and caps are for en-
suring the correct reassembly.
(b) Using a 12 mm socket wrench, remove the 2 connecting
rod cap bolts.
(c) Using the 2 removed connecting rod cap bolts, remove
the connecting rod cap and the lower bearing by wiggling
the connecting rod cap right and left.
HINT:
Keep the lower bearing inserted to the connecting rod cap.
(d) Clean the crank pin and bearing.
(e) Check the crank pin and bearing for pitting and scratches.
(f) Lay a strip of Plastigage on the crank pin.

If the crank pin or bearing is damaged, replace the bearings. If
necessary, replace the crankshaft.
HINT:
If replacing a bearing, replace it with one that has the same
number as the connecting rod. There are 3 sizes of standard
bearings: 1, 2 and 3.
Standard bearing center wall thickness:
Mark 11.485 to 1.488 mm (0.0585 to 0.0586 in.)

(176 to 194_F).
(b) Using a plastic−faced hammer and brass bar, lightly tap
out the piston pin and remove the connecting rod.
HINT:
SThe piston and pin are a matched set.
SArrange the pistons, pins, rings, connecting rods and
bearings in the correct order.
8. INSPECT CRANKSHAFT THRUST CLEARANCE
(a) Using a dial indicator, measure the thrust clearance while
prying the crankshaft back and forth with a screwdriver.
Standard thrust clearance:
0.040 to 0.240 mm (0.0016 to 0.0094 in.)
Maximum thrust clearance: 0.30 mm (0.0118 in.)

same number. If the number of the bearing cannot be de-
termined, select the correct bearing by adding together
the numbers imprinted on the cylinder block and crank-
shaft, and then selecting the bearing according to the
chart below. There are 4 sizes of standard bearings: 1, 2,
3 and 4.
