Chapter 5 Preventative Maintenance and Component Replacement
3. Remove and retain four M6 x 12 bolts from the top of the Fan Support
Bracket, and remove the bracket from the Fan Assembly.
4. Remove the Wiring Cover and disconnect the wiring.
5. Install the fan in the reverse order of its removal. Rotate the impeller by
hand to ensure that there is no contact with the Fan Housing Assembly.
Fan Balance
Fan impellers are statically and dynamically balanced within acceptable
tolerances at the factory. Damage in shipping or from incorrect handling or
installation may upset the balance. An improperly balanced impeller can lead to
excessive vibration causing undue wear on the entire unit.
If vibration is excessive, shut down the fan and determine the cause. Common
causes of excessive vibration include:
• Drive support structure not sufficiently rigid or level
• Loose mounting bolts
• Loose impeller or bushing
ATTENTION: The fan must be handled with extreme care. Failure to do so can
alter the fan balance and will negatively impact performance and life span.
