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 thrust bearings (6) from the bearing cap

(9).

5. Remove the crankshaft (5).

6. Remove the upper thrust bearings(4).

7. Remove the upper bearing shells (3) from crankcase.

14. Measure crankshaft bearing journal diameter (F).

Notice

When measured in A and B, the runout should not exceed
0.010mm.

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  Torque

35 - 40 Nm

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.

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 bearing.

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 adjust 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).
