(2)
Check for twist
Maximum twist:
0.15 mm (0.0059 in. ) per 100 mm (3.94 in.)
If twist is greater than maximum, replace the connecting rod as-
sembly.
(f)
Inspect the piston pin oil clearance.
(1)
Using a caliper gauge, measure the inside diameter
of the connecting rod bushing.
Bushing inside diameter:
26.008
−
26.020 mm (1.0239
−
1.0244 in.)
(2)
Using a micrometer, measure the piston pin diame-
ter.
Piston pin diameter:
26.000
−
26.012 mm (1.0236
−
1.0241 in.)
(3)
Subtract the piston pin diameter measurement from
the bushing inside diameter measurement.
Standard oil clearance:
0.004
−
0.012 mm (0.0002
−
0.0005 in.)
Maximum oil clearance: 0.05 mm (0.0020 in.)
If the oil clearance is greater than maximum, replace the bush-
ing. If necessary, replace the piston and piston pin as a set (See

).
(g)
Inspect the connecting rod bolts.
Install the cap nut to the connecting rod bolt. Check that
the cap nut can be turned easily by hand to the end of the
thread.
If the cap nut cannot be turned easily, measure the outside di-
ameter of the connecting rod bolt with vernier calipers.
Standard outside diameter:
8.40
−
8.60 mm (0.3307
−
0.3386 in.)
Minimum outside diameter: 8.00 mm (0.3150 in.)
