INSPECTION
1. REMOVE GASKET MATERIAL
Using a gasket scraper, remove all the gasket material from the
top surface of the cylinder block.
2. CLEAN CYLINDER BLOCK
Using a soft brush and solvent, thoroughly clean the cylinder
block.
NOTICE:
If the cylinder is washed at high temperatures, the cylinder
liner sticks out beyond the cylinder block, so always wash
the cylinder block at a temperature of 45°C (113°F) or less.
3. INSPECT TOP SURFACE OF CYLINDER BLOCK FOR
FLATNESS
Using a precision straight edge and feeler gauge, measure the
surface contacting the cylinder head gasket for warpage.
Maximum warpage: 0.07 mm (0.0028 in.)
If warpage is greater than maximum, replace the cylinder block.
4. INSPECT CYLINDER FOR VERTICAL SCRATCHES
Visually check the cylinder for vertical scratches.
If deep scratches are present, replace the cylinder block.

If the end gap is greater than maximum, replace the piston ring.
If the end gap is greater than maximum, even with a new piston
ring, replace the cylinder block.
12. INSPECT PISTON PIN FIT
At 60°C (140°F), you should be able to push the piston pin into
the piston pin hole with your thumb.
13. INSPECT CONNECTING ROD ALIGNMENT
Using a rod aligner and feeler gauge, check the connecting rod
alignment.

Check for out±of±alignment.
Maximum out±of±alignment:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If bend is greater than maximum, replace the connecting rod as-
sembly.

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.
14. INSPECT PISTON PIN OIL CLEARANCE

Piston pin diameter:
21.997 ± 22.006 mm (0.8660 ± 0.8664 in.)
(c) Subtract the piston pin diameter measurement from the
bushing inside diameter measurement.
Standard oil clearance:
0.005 ± 0.011 mm (0.0002 ± 0.0004 in.)
Maximum oil clearance: 0.05 mm (0.0020 in.)
15. INSPECT CONNECTING ROD BOLTS
Using vernier calipers, measure the tension portion diameter of
the bolt.
Standard diameter: 7.2 ± 7.3 mm (0.284 ± 0.287 in.)
Minimum diameter: 7.0 mm (0.276 in.)
If the diameter is less than minimum, replace the bolt.
16. INSPECT CRANKSHAFT FOR CIRCLE RUNOUT
(a) Place the crankshaft on V±blocks.
(b) Using a dial indicator, measure the circle runout, as
shown in the illustration.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
17. INSPECT MAIN JOURNALS AND CRANK PINS
(a) Using a micrometer, measure the diameter of each main
journal and crank pin.
Main journal diameter:
60.988 ± 61.000 mm (2.4011 ± 2.4016 in.)
Crank pin diameter:
52.992 ± 53.000 mm (2.0862 ± 2.0866 in.)
If the diameter is not as specified, check the oil clearance.
(See page EM±83)
