5.15.7
Fit the coupling cover to the new pump-motor
CAUTION
Ensure that the pump-motor flange and the bottom flange of the coupling cover are clean and free of burrs. If
you do not, the pump-motor and coupling cover may be misaligned and you may damage the pump-motor, the
pump or the torque limiter or drive coupling when you operate the pump.
1. Refer to
. Inspect the bottom flange of the coupling cover (12) and the flange of the pump-motor (8).
The flanges must be free of burrs and dirt. If necessary, clean or refinish the flanges.
2. Fit the coupling cover (12) onto the flange of the pump-motor (8). Ensure that the coupling cover is orientated
correctly (as noted in
): one of the coupling cover guards (2) must be at 90° to the terminal-box
on the pump-motor.
3. Fit the four bolts (9) and tighten the bolts to secure the coupling cover (12) to the pump-motor (8); note that
you will fully tighten the bolts in
5.15.8
Refit the pump-motor and coupling cover to the pump (without the motor change
frame)
CAUTION
Ensure that the bottom flange of the pump gearbox and the top flange of the coupling cover are clean and free
of burrs. If you do not, the pump gearbox and coupling cover may be misaligned and you may damage the pump-
motor, the pump or the torque limiter or drive coupling when you operate the pump.
. Undo and remove the four bolts (3) which secure each of the two coupling cover guards
(2) and remove the guard from the coupling cover (12).
2. Inspect the top flange of the coupling cover (12) and the bottom flange of the pump gearbox (1); they must be
free of burrs and dirt. If necessary, clean or refinish the flanges.
3. Use suitable lifting equipment to lift the pump-motor and coupling cover onto the bottom of the pump frame.
Carefully slide the pump-motor and coupling cover assembly so that it is directly under the pump and so that the
pump-motor terminal-box is directly below the gearbox oil drain-plug.
4. Turn the torque limiter or coupling hub (15) until the drive dogs align with the gaps between the drive coupling
element in the coupling hub (15).
5. Use the bolts (11) to secure the coupling cover and pump-motor assembly to the pump gearbox (1).
6. Refer to torque limiter or coupling amendment. Check the gap between the bottom face of the coupling hub
(15) and the inner faces of the drive dogs. If the gap is correct, continue at
.
7. If the gap is not correct:
Check that the bottom flange of the coupling cover (12) is correctly located against the top flange of the
pump-motor: refer to
.
Check that the top flange of the coupling cover (12) is correctly located against the bottom flange of the
pump gearbox (1): refer to
and to the WARNING at the start of this section.
WARNING
Ensure that the pump-motor, motor coupling and coupling cover assembly does not fall over when
you move it. If it falls over, it can cause injury to people.
