Notice
If the max. length of bolts(L) exceed 63.8mm, replace them.
19. Coat the new crankshaft with engine oil and place it on the
crankcase.
20. Install the crankshaft bearing caps according to marking
and tighten the bolts.
Tightening Torque 55 Nm + 90°
Notice
Install from No. 1 cap.
22. Rotate the crankshaft with hand and check whether it
rotates smoothly.
23. Measure crankshaft bearing axial clearance.
Clearance 0.100 - 0.245mm
Notice
If the clearance is out of standard, adjust the axial clearance
of crankshaft bearing by replacing the thrust washers.
Dial Gauge 001 589 53 21 00
Dial Gauge Holder 363 589 02 21 00
Notice
The same thickness of thrust washers should be installed
on both sides of the thrust bearing.

28. Remove the connecting rod bearing cap.
29. Install the piston.
30. Rotate the crankshaft by hand and check whether it rotates
smoothly.
31. If the bearings are damaged,
- replace the oil presser relief valve.
- clean the oil pump and oil filter housing carefully and
replace the hose if necessary.
Notice
After assembling the engine, check the camshaft timing,
adjust the start of fuel injection and check the TDC sensor
bracket setting.
32. Fill oil and run the engine and then check the oil pressure
and oil level.
Notice
Install the original oil filter element and then change the
engine oil and oil filter element after 1,000 - 1,500km. 27. Measure the radial clearance (L) of the connecting rod
bearing.
Example)Measured value ‘J’ = 47.700mm
Measured value ‘K’ = 47.653mm
Clearance ‘L’ = 0.047mm
Radial Clearance ‘L’ 0.026 - 0.068mm
Notice
If the clearance is out of standard, adjust the radial
clearance of connecting rod bearing by replacing the
connecting rod bearing shells. 26. Measure connecting rod bearing journal diameter (K).
Notice
Refer to measurement of the crankshaft bearing journal
diameter.
24. Insert the new connecting rod bearing shells into the
connecting rod and connecting rod bearing cap and tighten
the 12-sided stretch bolts (11).
25. Measure inner diameter of connecting rod bearing.
Tightening Torque 40 Nm + 90°

Checking
Notice
The noise which continues short time during short travel
(frequent starting of the engine) or engine starting after a
long time storage is normal operating conditions. So, it does
not need to be repaired. Determine the malfunctions in valve
clearance compensation device with noise through following
tests. If defective, replace as respectively.
1. Run the engine at more than 3000rpm for approx. 4 minutes.
2. Stop the engine. After 5minutes, check the engine oil level
and adjust if necessary.
3. Remove the cylinder head cover.
4. Check the valve tappets at TDC position of each cylinders.
5. Using a drift, lightly press the valve tappet and measure
clearance between the cam and valve tappet.
Notice
If the clearance exceeds 0.4mm, replace the valve tappet.
6. If a valve tappet moves down too far in comparison to the
others, replace the valve tappet.
7. Rotate the engine and check the remaining valve tappets.
Notice
lUnnecessary rotation of the engine will damage the valve
tappets.
lDo not rotate the engine by using the camshaft sprocket
bolt or to the opposite direction of the engine rotation.
