5. Coat a little oil on the sealing lip of new radial seal
and contacting surface.
Notice
Don’t use grease.
6. Insert the new radial seal (4) onto the oil seal as-
sembler (7).
Notice
The sealing lip of the repair radial seal is offset to the
inside by 3mm to ensure that it does not run in any
groove which the standard radial seal may have left
on the crankshaft flange.

B Repair Radial Seal
7. Install the outer oil seal assembler on he seal and by
tightening the bolts, press the radial seal into the
end cover as far as the stop.
Notice
The seal must be positioned exactly at right angles
in the end cover to ensure that it provides a proper
seal.

Replacement Procedure
1. Pull out the radial seal (1) and be careful not to dam-
age the sealing surface of timing case cover.
2. Thoroughly clean the mounting bore of the radial
seal.
3. Coat a little oil on the sealing lip of new radial (1) and
contact surface.
Notice
Don’t use grease.
4. Install the radial seal (1) by using a sleeve (4).
Notice
Align the groove of sleeve and woodruff key(arrow).

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).
