Whilst mounting the bearings:
- Always make sure the back plate is clean and free of dust and debris, as this
could misalign the bearing or even result in the incorrect torque being achieved
during the installation, resulting in irreparable damage to the bearing.
- Install the unit by pushing on the inner ring of the bearing using light pressure –
do not force the bearing onto the mount!

How to avoid failures?
- Always apply the tightening torques as
recommended by the OE vehicle
manufacturer - this determines the preload
of the bearing!
- Always clean and set up the bearing correctly.
Risks:
• Excessive force on the bearings could result
in misalignment during installation,
eventually resulting in the bearing collapsing.
• A wrongly positioned bearing or installation
on a dirty axle could also lead to
premature failure.
- Apply the right belt tension.
Risks:
• Incorrect belt tension can affect the
performance of the bearings on the
engine. If there is too little tension, there is
a risk of the belt jumping. Too much tension
could lead to premature bearing failure
and ultimately the failure of the timing
belt itself. Either scenario offers a high risk
of valve-to-piston damage in the engine.
- Bad tightening torque.
Risks:
• The engine vibrations and the belt load will
lead to the complete unscrewing of the bolts/
nuts. This will end up in the disassembling of
the inner ring and therefore the bearing
failure.
• In this case, the seal has come out of the
bearing and the ball cage with the
balls have been ejected.
