5. Measure:
• Crankshaft journal diameter "a"
Out of specification → Replace the crank-
shaft.
NOTE:

6. Measure:
• Crankshaft journal bearing inside diameter
"a"
Out of specification → Replace the crank-

Measure the inside diameter of each crankshaft
journal bearing at two places.
Crankshaft journal bearing inside
diameter
50.010–50.030 mm (1.9689–

5-79
NOTE:
Calculate the clearance by subtracting the
crankshaft journal diameter from the crankshaft
journal bearing inside diameter.
Crankshaft-journal-to-crankshaft-
journal-bearing clearance
0.030–0.060 mm (0.0012–0.0024
in)
