Preventive maintenance

Preventive maintenance work must be carried out at regular
intervals. Make sure:
• that there is no abnormal noise or vibrations
• that air oil cooler is securely fixed
• that the cooler matrix is clean, debris will reduce the cooling
capacity
• that the air oil cooler is free from damage, replace damaged
components
• that the air oil cooler is free from leaks
• that warning labels are in good condition, replace any
damaged/missing label immediately.
Annually: Check the electrical installation. This may only be
made by a qualified electrician.
Cleaning
Caution Risk of bodily injury. Prior to cleaning, disconnect
all motor power supplies.
Caution Risk of severe burns. The air oil cooler could
become extremely hot during operation. Make sure the air
oil cooler is cool before touching.
Air oil cooler When cleaning the exterior of the cooler, for
instance using water, disconnect all power supplies. Be aware
of the electric motor protection standard.
Cooler matrix The air fins of the matrix can be cleaned by
blowing through with compressed air. If necessary a high
pressure washing system and degreasing agent can be used.
When using a high-pressure washing system point the jet par-
allel to the air fins. See Figure 9.
Fan housing Remove the cooler matrix when cleaning the
inside of the fan housing. To clean the inside of the fan housing,
use compressed air. If necessary a degreasing agent can be
used. Blow with compressed air from the electric motor side
through the fan guard.

Air Oil Coolers, MAC
Removing the electric motor and the fan
Caution Risk of severe burns. The air oil cooler could
become extremely hot during operation. Make sure the air
oil cooler is cool before touching.
Caution Risk of bodily harm. Prior to maintenance,
disconnect the electric motor power supply.
Note! Some fan hubs are fixed, see Figure 11, and some are
detachable, see Figure 12 and Figure 13. The fan is balanced
together with the hub as from size MAC-033.
1. Turn off the system.
2. Disconnect the electric motor power supply.
3. Secure the electric motor.
4. Unscrew the screws with washer fixing the motor attach-
ment to the fan housing, see Figure 10. If the air oil cooler is
fitted with a motor bracket, unscrew the screws with wash-
ers fixing the motor bracket to the feet.
5. Unscrew the screw with washer fixing the fan to the motor
shaft. See Figure 11. Pull with care the fan and hub from the
motor shaft. Use a pulley if required.
6. Unscrew the screws fixing the motor to the motor attach-
ment. See Figure 14. If the air oil cooler is fitted with motor
bracket, unscrew the screws with washers fixing the motor
to the motor bracket.
7. Remove the motor.
If further dismounting of the fan is required, label all details to
ensure correct mounting, first of all with regard to balance and
direction of rotation. See Figure 15.
Mounting of the electric motor and fan
Note! Some fan hubs are fixed, see Figure 11, and some are
detachable, see Figure 12 and Figure 13. The fan is balanced
together with the hub as from size MAC-033.
1. If the air oil cooler is fitted with motor bracket, fit the motor
to the motor bracket.
2. Secure the electric motor to the motor attachment.
See Figure 14.
3. Fit the hub groove to the motor spline. Lube the hub
with ethanol and secure the fan/hub to the motor shaft.
If required, knock carefully with e.g. a rubber mallet. Use
Loctite® on the screw and secure the fan/hub on the motor
shaft with screws. See Figure 11.
4. Make sure that the fan is fitted to the motor shaft with out
too much play.
5. Place the motor attachment with fan, fan guard, motor and
bracket, if any, in the fan housing.
6. Adjust the fan guard and motor and secure the motor
attachment in the fan housing with screws. See Figure 10.
Secure the bracket with screws.
7. Make sure that the fan is centred and rotates freely (using
hand force). If required, adjust the location of the fan guard
and motor.
8. Check the screws for tightness.
9. Connect the electric motor power supply.
10. Proceed to Prior to start-up and At start-up.
