pump, and it will be difficult to move the driver.
When a complete pump set comes pre-assembled from the
factory, the coupling has been accurately aligned by means of
shims inserted under the pump and engine.
During transport and installation, the pump/driver alignment may
have been affected. Therefore always check the alignment when
the pump set has been installed.
Check the final alignment when the pump has obtained its
operating temperature under normal operating conditions.
