ening torque first.
 If the preload torque exceeds the specified value, replace
collapsible spacer and tighte n it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.
6. Make a stamping for identificati on of front oil seal replacement
frequency. Refer to "IDENTIFICATION STAMP OF REPLACE-
MENT FREQUENCY OF FRONT OIL SEAL".

tector.
c. Put a suitable drift on the center of side flange, then drive it until sound changes.
NOTE:
When installation is completed, driving sound of the side flange turns into a sound which seems to affect
the whole final drive.
d. Confirm that the dimension of the side flange installation (Mea- surement A) in the figure comes into the following.
9. Install drive shaft. Refer to RAX-10
.
10. Install rear wheel sensor. Refer to BRC-52
.
11. Install center muffler. Refer to EX-3
.
12. Refill gear oil to the final drive and check oil level. Refer to RFD-
9, "Changing Differential Gear Oil".
13. Check the final drive for oil leakage. Refer to RFD-9, "
Checking
Differential Gear Oil".
