Notice
The crankshaft bearing caps are marked with
stamped numbers. Remove the bearing cap from
the vibration damper side.
3. Remove the crankshaft bearing caps (9) and lower
thrust bearings (7).
4. Remove the lower thrust bearings (6) from the bear-
ing cap (9).
5. Remove the crankshaft (5).
6. Remove the upper thrust bearings(4).
7. Remove the upper bearing shells (3) from crank-
case.

8. Thoroughly clean the oil gallery.
9. Select a proper new bearing shells with reference to
table.
10. Coat the new bearing shells with oil and insert into
the crankcase and into the crankshaft bearing caps.
Notice
Do not mix up upper and lower crankshaft bearing
shells.
11. Install the bearing caps according to marking and
tighten the 12--sided stretch bolts.
Tightening Torque35-- 40 N∙m (26-- 30 lb-ft)
Notice
No. 1 is vibration damper side.
12. Measure crankshaft bearing diameters (E).
Extension 366 589 00 21 05
13. Measure at 3 points (A, B and C) and if the average
value of B and C is less than A’s value, the average
value of B and C is the mean value and if more than
A’s value, A’s value is the mean value.
14. Measure crankshaft bearing journal diameter (F).
Notice
When measured in A and B, the runout should not
exceed 0.010mm.

15. Measure radial clearance of crankshaft bearing (G).
Clearance ’G’0.027 -- 0.051mm
Notice
If ’G’ is out of standard, replace the bearing shells
and adjust the radial clearance of crankshaft bear-
ing.
Example) Measured value ’E’ = 57.700mm
Measured value ’F’ = 57.659mm
——————————————
Clearance ’G’ = 0.041mm
16. Remove the crankshaft bearing cap.
17. Measure width of thrust bearing journal (H) and ad-
just with proper thrust bearings (see table).
Notice
The same thickness of thrust washers should be
installed on both sides of the thrust bearing.
18. Coat the upper thrust bearing (4) with oil and insert
into the crankcase so that the oil grooves are facing
the crank webs (arrow).
19. Coat the lower thrust bearing (7) with oil and insert
into the crankshaft bearing cap so that the oil
grooves are facing the crank webs (arrow).
Notice
The retaining lugs should be positioned in the
grooves (arrow).

Notice
If the max. length of bolts(L) exceed 63.8mm, re-
place 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 Torque55 N∙m (41 lb-ft) + 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.
Clearance0.100 -- 0.245 mm
Notice
If the clearance is out of standard, adjust the axial
clearance of crankshaft bearing by replacing the
thrust washers.

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).
Tightening Torque40 N∙m (30 lb-ft) + 90_
25. Measure inner diameter of connecting rod bearing.
26. Measure connecting rod bearing journal diameter
(K).
Notice
Refer to measurement of the crankshaft bearing
journal diameter.
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.
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.
