Alignment troubleshooting
Symptom Cause Remedy
Horizontal (side-to-side) alignment cannot
be obtained (angular or parallel). The driver feet are bolt-bound. Loosen the pump's hold-down bolts, and
slide the pump and driver until you
achieve horizontal alignment.
The baseplate is not leveled properly and
is probably twisted.
1. Determine which corners of the base-
plate are high or low.
2. Remove or add shims at the appropri-
ate corners.
3. Realign the pump and driver.
Vertical (top-to-bottom) alignment cannot
be obtained (angular or parallel). The baseplate is not leveled properly and
is probably bowed.
1. Determine if the center of the base-
plate should be raised or lowered.
2. Level screws equally at the center of
the baseplate.
3. Realign the pump and driver.
