11. Remove rear oil seal retainer assembly.
12. Remove main bearing cap.
13. Remove crankshaft.
14. Remove cylinder block.
Inspection and Repair
1. Remove the cylinder head gasket and any other
material adhering to the upper surface of the cylinder
block. Be very careful not to allow any material to
accidentally drop into the cylinder block. Be very
careful not to scratch the cylinder block.
2. Carefully remove the oil pump, rear oil seal retainer,
and crankcase assembly installation surface seal.
3. Wipe the cylinder block clean.
4. Visually inspect the cylinder block. If necessary, use a
flaw detector to perform a dye penetrate and
hydraulic (or air pressure) test. If cracking or other
damage is discovered, the cylinder block must either
be repaired or replaced.
Flatness
1. Using a straight–edge and feeler gauge, check that
the upper surface of the cylinder block is not warped.
CAUTION: Be very careful not to allow any material
to accidentally drop into the upper surface of the
cylinder block. Be very careful not to scratch the
upper surface of the cylinder block.
2. The cylinder block must be reground or replaced if the
warpage exceeds the limit.
Warpage
Limit : 0.15 mm (0.0059 in)
Maximum repairable limit: 0.15 mm (0.0059 in)

Cylinder Bore
Use a cylinder gauge to measure the cylinder bore
diameter in both the axial and thrust directions. Each
measurement should be made at six points.CAUTION: Be very careful not to allow any material
to accidentally drop into the upper surface of the
cylinder block. Be very careful not to scratch the
upper surface of the cylinder block.
Cylinder Bore Inside Diameter
Limit : 93.530 (3.6823)
If the measurement exceed the specified limit, the
cylinder block must be replaced.
Diameter
Grade A : 93.400 mm–93.410 mm
(3.6772 in–3.6776 in)
Grade B : 93.411 mm–93.420 mm
(3.6776 in–3.6779 in)
Grade C : 93.421 mm–93.430 mm
(3.6780 in–3.6783 in)

NOTE: For information on piston diameter, please refer
to the section ”Inspection of the Piston and Connecting
Rod Assembly” in this manual.
The ”Grade” mark (1) is stamped at the position
illustrated.

Reassembly
1. Install cylinder block.
2. Install crankshaft.
Install the main bearings to the cylinder block and
the main bearing caps.
Be sure that they are positioned correctly.
Apply new engine oil to the upper and lower main
bearing faces.
NOTE: Do not apply engine oil to the bearing back faces.

(2) Number 2 and 3 main bearing upper.
(3) Number 2 and 3 main bearing lower.
Carefully mount the crankshaft.
Apply engine oil to the thrust washer.
Assemble the thrust washer to the No. 3 bearing
journal. The oil grooves must face the crankshaft.

3. Install rear oil seal retainer.
Remove oil on cylinder block and retainer fitting
surface.

10. Install oil pipe and O-ring.
11. Install crankcase with oil pan.
1. Completely remove all residual sealant, lubricant
and moisture from the sealing surfaces. The
surfaces must be perfectly dry.
2. Apply a correct width bead of sealant (TB– 1207C
or its equivalent) to the contact surfaces of the
crankcase. There must be no gaps in the bead.
3. The oil pan must be installed within 5 minutes
after sealant application to prevent premature
hardening of sealant.
4. Tighten the bolts and nuts to the specified torque.
Torque : 10 Nꞏm (1.0 Kgꞏm/89 lb in)

Radiator
The radiator is a tube type with corrugated fins. In order to
raise the boiling point of the coolant, the radiator is fitted
with a cap in which the valve is operated at 88.2

Anti Freeze Solution
Relation between the mixing ratio and freezing
temperature of the EC varies with the ratio of
anti–freeze solution in water. Proper mixing ratio can
be determined by referring to the chart. Supplemental
inhibitors or additives claiming to increase cooling
capability that have not been specifically approved by
Isuzu are not recommended for addition to the cooling
system.
