11. INSTALLATION OF LATERAL ROD MOUNTING BOLT
Install the lateral rod mounting bolt from the direction
shown in the illustration.
4. INSTALLATION OF WHEEL BEARING NUT (1) After tightening the wheel bearing nut to 20
Nm (14 ft.lbs.),
turn the hub a few times to seat the bearing.
(2)In order to seat the bearing properly, turn the hub (brake
drum) 180” or more and then return it 360” or more;
repeat this procedure again three or more times.
(3) Return the wheel bearing nut to 0 Nm
(0 ftlbs.).
(4) After tightening the wheel bearing nut at a torque of 10 Nm (7
ftlbs.), rotate the hub again in the same way as
described in step (2) so as to seat the bearing.
(5) Then once again tighten the wheel bearing nut to 10 Nm (7 ft.lbs.).
(6) Install the lock cap and cotter pin.
(7) If the position of the cotter pin is not matched with the holes of the lock cap, reposition the lock cap so that the
holes align. If this can not be accomplished, back off the
nut by not more than 15”.
Caution
Check to be sure that the lock nut cannot be
loosened manually.
(8) After setting the cotter pin in place, seat the bearing in
the same manner as in step (2).
