CHANGING THE BEARINGS
Read carefully (PRECAUTIONS AND GENERAL
INFORMATION).
Each time they are disassembled the bearings
must be checked and, if necessary, renewed.
Clean both sides of the hub with a cloth.
Removal
Work from the left side of the vehicle:
Insert a punch (not pointed) into the wheel hub and
work on the right bearing inner ring (1), changing the
contact points in rotation (90
°
) in order not to misalign
the bearing.
Remove the right bearing (1).
Remove the spacer (2).
Work from the right side of the vehicle:
Keep the pad perpendicular to the bearing
(aligned with the wheel axis) in order not to
misalign or ruin the bearing.
Insert a pad (diameter 0.59 in or 15 mm) into the
wheel hub and rest it against the left bearing inner ring
(3).
Hit the pad gently several times with a rubber hammer
and remove the bearing.
Refitting
Work from the right side of the vehicle:
Rest the bearing against the wheel hub.
Keep the pad perpendicular to the bearing
(aligned with the wheel axis) in order not to
misalign or ruin the bearing.
Rest a pad (diameter 1.22 in or 31 mm) against the
outer edge of the bearing.
Hit the pad gently several times with a rubber hammer
and insert the right bearing (1) completely.
Insert the spacer (2).
