Removal & Installation Procedure
1. Remove the bearing cab bolt.
2. Remove the bearing caps (8).
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 bearing shell (6) from the bearing
cap (9).
6. Remove the upper thrust bearings (4).
7. Remove the upper bearing shells (3) from
crankcase.
5. Remove the crankshaft (5).

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.
Installation Notice
Tightening Torque
55 N•m (41 lb-ft)+ 90°
12. Measure crankshaft bearing diameters (E) using
the dial gauge 001 589 53 21 00 and 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.
No. 1 is vibration damper side.

14. Measure crankshaft bearing journal diameter (F).
Notice: When measured in A and B, the runout
should not exceed 0.010 mm.
15. Measure radial clearance of crankshaft bearing
(G).
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).
16. Remove the crankshaft bearing cap.
17. Measure width of thrust bearing journal (H) and
adjust with proper thrust bearings (see table).
Notice: The same thickness of thrust washers
should be installed on both sides of the thrust
bearing.
Clearance ‘G’
0.027 - 0.051 mm
Notice: If ‘G’ is out of standard, replace the
bearing shells and adjust the radial clearance of
crankshaft bearing.
Example) Measured value ‘E’ = 57.700 mm
Measured value ‘F’ = 57.659 mm
Clearance ‘G’
= 0.041 mm

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).
22. Rotate the crankshaft with hand and check whether
it rotates smoothly.
23. Measure crankshaft bearing axial clearance using
dial gauge 001 589 53 21 00 and dial gauge holder
363 589 02 21 00.
Notice: If the max. length of bolts (L) exceed
63.8 mm, replace them.
20. Coat the new crankshaft with engine oil and place
it on the crankcase.
21. Install the crankshaft bearing caps according to
marking and tighten the bolts.
Installation Notice
Tightening Torque
55 N•m (41 lb-ft)+ 90°
Install from No. 1 cap.
Notice: If the clearance is out of standard, adjust
the axial clearance of crankshaft bearing by
replacing the thrust washers.
Notice: The same thickness of thrust washers
should be installed on both sides of the thrust
bearing.
Clearance
0.100 - 0.245 mm
