5.14 Replace the motor bearings
You must only replace the motor bearings if you
have been suitably trained in all the procedures
required to dismantle and reassemble the motor,
and to replace the bearings.
Take note of the following when you replace the
motor bearings:
• You will need a Motor bearing kit: refer to
Section 7.3.
• Use the procedures in this manual to remove
and refit the motor.
• Only use approved procedures to dismantle
and reassemble the motor, and to replace the
bearings.
5.15 Overhaul the pump
We recommend that the pump is given a major
overhaul every three years. Such an overhaul is
outside the scope of this manual and should be done
by qualified BOC Edwards service personnel:
contact your supplier or BOC Edwards.
WARNING
Do not replace the motor bearings
unless you have been suitably trained
in the necessary procedures. If you
are not suitably trained, you may
damage the motor and it may not
operate correctly or safely.
