HINT:
If using a bearing, replace it with one having the same number.
If the number of the bearing cannot be determined, select the
correct bearing by adding together the numbers imprinted on
the cylinder block and crankshaft, then refer to the table below
for the appropriate bearing number. The No.1 and No.4 journal
bearings have 5 standard bearing sizes, marked º3º, º4º, º5º, º6º
and º7º accordingly. The No.2 and No.3 journal bearings have
5 standard bearing sizes, marked º1º, º2º, º3º, º4º and º5º ac-
cordingly.

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.

5. INSPECT CYLINDER BORE DIAMETER
Using a cylinder gauge, measure the cylinder bore diameter at
positions A, B and C in the thrust and axial directions.
Standard diameter:
87.500 ± 87.512 mm (3.4449 ± 3.4453 in.)
Maximum diameter: 87.52 mm (3.4457 in.)
If the diameter is greater than maximum, replace the cylinder
block.
6. REMOVE CYLINDER RIDGE
If the wear is less than 0.2 mm (0.008 in.), using a ridge reamer,
grind the top of the cylinder.
7. INSPECT 12 POINTED HEAD MAIN BEARING CAP
BOLTS
Using vernier calipers, measure the tension portion diameter of
the bolt.
Standard diameter:
7.500 ± 7.600 mm (0.2953 ± 0.2992 in.)
Minimum diameter: 7.20 mm (0.2835 in.)
If the diameter is less than minimum, replace the bolt.
8. CLEAN PISTON
(a) Using a gasket scraper, remove the carbon from the pis-
ton top.
