• |
To avoid damaging the cylinder head, wait until the engine coolant
temperature drops below normal temperature (20°C [68°F]) before
removing it.

• |
When handling a metal gasket, take care not to fold the gasket
or damage the contact surface of the gasket.
|
• |
To avoid damage, unplug the wiring connectors carefully while
holding the connector portion.
|
|
• |
Mark all wiring and hoses to avoid misconnection.

|
17. |
Lift the crankshaft (A) out of the cylinder block, being careful not

•
|
Arrange the main bearings and thrust bearings in the
correct order.
|
•
|
Keep the main bearing caps with their bearings assembled
together.
|
|
|
1. |
Check the crankshaft main bearing oil clearance.
(1) |
To check main bearing-to-journal oil clearance, remove the bearing
caps with their lower bearings.
|
(2) |
Clean each main journal and lower bearing with a clean shop
towel.
|
(3) |
Place one strip of plastigage across each main journal.
|
(4) |
Reinstall the bearing caps with their lower bearings, then tighten
the bolts.
Tightening torque :
17.7 ~ 21.6 N.m (1.8 ~ 2.2 kgf.m, 13.0 ~ 15.9 lb-ft)
+ 88 ~ 92°
|
• |
Do not turn the crankshaft.
|
• |
Always use new crankshaft main bearing cap bolts.
Crankshaft main bearing cap bolts are toque-to-yield
bolts designed to be permanently elongated beyond
the state of elasticity when torqued, so if
the bolts are removed and reused, it may cause
the bolts to break or fail to maintain clamping
force.
|
|
|
(5) |
Remove the bearing caps with their lower bearing again, and
measure the widest part of the plastigage.
Main bearing oil clearance :
Standard : 0.006 ~ 0.024 mm (0.0002 ~ 0.0009 in)
Limit : 0.05 mm (0.0020 in)
|
|
(6) |
If the plastigage measures too wide or too narrow, remove the
upper and lower bearing and then install a new bearings with
the same color mark. Recheck the oil clearance.
• |
Do not file, shim, or scrape the bearings or
the cap to adjust clearance.
|
|
|
(7) |
If the plastigage shows the clearance is still incorrect, try
the next larger or smaller bearing. Recheck the oil clearance.
• |
If the proper clearance cannot be obtained by
using the appropriate larger or smaller bearings,
replace the crankshaft and start over.
|
|
• |
If the marks are indecipherable because of an
accumulation of dirt and dust, do not scrub
them with a wire brush or scraper. Clean them
only with solvent or detergent.
|
|
|
(8) |
Select the bearing by using selection table.
Letters have been stamped on the side of block as a mark for
the size of each of the 5 main journal bores.
Use them, and the numbers or letters stamped on the crank (marks
for main journal size), to choose the correct bearings.

Check the crankshaft end play.
Using a dial indicator, measure the thrust clearance while prying the
crankshaft back and forth with a screwdriver.
Crankshaft end play
Standard : 0.05 ~ 0.25 mm (0.0020 ~ 0.0098 in)
Limit : 0.30 mm (0.0118 in)
|
If the end play is greater than specification, replace the thrust bearings
as a set.
Thickness of thrust bearing :
1.925 ~ 1.975 mm (0.0758 ~ 0.0778 in)
|
|
3. |
Inspect the crankshaft main journals and pin journals.
Using a micrometer, measure the diameter of each main journal and pin
journal.
Main journal diameter :
47.942 ~ 47.960 mm (1.8875 ~ 1.8882 in)
Pin journal diameter :
41.954 ~ 41.972 mm (1.6517 ~ 1.6524 in)

•
|
Always use new crankshaft main bearing cap bolts. Crankshaft
main bearing cap bolts are toque-to-yield bolts designed
to be permanently elongated beyond the state of elasticity
when torqued, so if the bolts are removed and reused,
it may cause the bolts to break or fail to maintain
clamping force.

Tighten all the bolts with the specified torque in numerical
order first, then tighten all the bolts with the specified angle
in numerical order.
Tightening torque :
17.7 ~ 21.6 N.m (1.8 ~ 2.2 kgf.m, 13.0 ~ 15.9 lb-ft)
+ 88° ~ 92°
|

5900H on the ladder frame rail portion and install
it with in five minutes. If when sealant is
applied to cylinder block bottom position, sealant
position to be same with positon that is applied
to ladder frame rail position.
|
• |

holes.
|
|
|
(2) |
Install the ladder frame (A).
Tightening torque :
18.6 ~ 23.5 N.m (1.9 ~ 2.4 kgf.m, 13.7 ~ 17.4 lb-ft)
|
|
|
8. |
Install the other parts in the reverse order of disassembly.
•
|
