4.5.1 Aligning the pump and motor with a
straightedge ruler
1. Make a rough alignment of pump and motor, and
tighten the screws in the base frame to the correct
torque.

See the table Tightening torques.
2. Make a mark on the coupling, for instance with a
marker pen.

3. Hold a straightedge ruler against the coupling,
and determine the inaccuracy, if any, with a feeler
gauge.

4. Turn the coupling 90°, and repeat the
measurement with straightedge and feeler gauge.

• If the measured values are less than 0.13 mm,
the alignment is complete. Go to step 8.
5. Adjust the position of the motor. Loosen the
screws that hold the motor in place.

6. Insert shims with the required thickness.

7. Tighten the screws to the correct torque. Go to
step 3, and check the alignment once more.
