Dismounting the pump and coupling
1. Turn off the system.
2. Disconnect the power supply.
3. Make sure that the system is de-pressurized.
4. Disconnect the oil inlets and outlets.
5. Disconnect the hydraulic hoses from the cooler matrix.
6. Remove the screws and rubber steel washers fixing the pump
to the electric motor.
7. Remove the pump and the gear ring of the coupling.
The pump and the coupling parts can now be replaced.
8. Loosen the stop screw of the shaft coupling part.
Remove the shaft coupling part from the crankshaft.
Mounting of the pump and coupling
1. Fit the shaft coupling part to the crankshaft.
Tighten the stop screw.
2. Install the pump and gear ring of the coupling.
3. Install the screws and rubber steel washer fixing the pump to
the electric motor.
4. Connect the hydraulic hoses.
See Figure 4
.
5. Connect the electric motor power supply.
6. Proceed to Prior to start-up and At start-up.
Dismounting the electric motor and fan
Caution
Risk of severe burns. As the cooling system
could become extremely hot during operation, make sure
the system is cool before touching.
Precaution
Risk of bodily harm. Prior to maintenance,
disconnect the electric motor power supply. The fan is
balanced together with the hub prior to delivery.
The fan is balanced together with the hub at delivery.
Note!
There are models with fixed hub
Figure 10
and models with
detachable hub
Figure 11 A and Figure 11 B.
1. Turn off the system.
2. Dismount the pump according to Dismounting the pump and
coupling.
3. Secure the motor.
4. Unscrew the screws with washers fixing the motor attachment
to the fan housing.
See Figure 9.
5. Unscrew the screws with washers fixing the motor support to
the feet. Pull the motor backwards.
6. Unscrew the screw with washer fixing the fan/hub to the
crankshaft.
See Figure 10.
Remove with care the fan/hub from
the crankshaft. Use a pulley if required.
7. Unscrew the screws with washers fixing the motor to the motor
attachment.
See Figure 12.
8. Unscrew the screws with washers fixing the motor to the motor
bracket.
9. Remove the motor.
If further dismounting of the fan is required, label all parts to ensure
correct assembly, first of all with regard to balance and direction of
rotation.
See Figure 13.
Mounting of the electric motor and fan
Note!
There are models with fixed hub
Figure 10 a
nd models with
detachable hub
Figure 11 A and Figure 11 B.
1. Fit the motor to the motor bracket.
2. Fit the motor to the motor attachment by screws.
See Figure 12.
3. Fit the hub groove to the motor spline. Lube the hub with
ethanol and secure the fan with hub to the cranks haft. If
required, knock carefully with e.g. a rubber mal let. Use Loctite
on the screw and secure the fan with hub on the crankshaft by
screws.
See Figure 10.
4. Make sure that the fan is fitted to the crankshaft without too
much play.
5. Place the motor attachment with fan, fan guard, motor and
motor support in the fan housing.
6. Adjust the fan guard and motor and fix the motor attachment
onto the fan housing by screws.
See Figure 9.
Secure the motor support by screws.
7. Make sure the fan is centred/aligned and rotates freely
(use hand force). If necessary, adjust the location of the fan
guard and motor.
8. Make sure all screws are tightened.
9. Connect the electric motor power supply.
10.Proceed to Prior to start-up and At start-up.
Oil filter unit FX3
Fitted with an filter unit type FX3 the oil will be cleaned in a sepa-
rate system. This is an excellent complement to the system oil
cleaning system. Filter unit FX3 is available as option.
Prior to start-up
1. Bleed filter by opening the vent plug at the top of filter approx-
imately two turns.
2. Fill filter until all air bleeds through the plug, then tighten plug.
3. Pressurize system fully and check for leaks; if leaks occur refer
to Routine maintenance.
Precaution
Failure to bleed the filter unit adequately will
increase the dissolved air content of the system oil, which
will shorten oil life and may cause other problems in the
system.
Routine maintenance
The filter unit FX3 does not normally require special attention
except for periodic monitoring of the pressure drop indicator.
Schedule replacement of filter element every six months or sooner,
and have ample supply of spare elements available.
Caution
Failure to depressurize the filter unit before servi-
cing element may result in personnel injury or damage to
property, or environment.
