C. Handling
caution
A hoist or suitable lifting device should
be used to lift pumping unit. Do NOT lift
the complete unit by the driver, the
pump shafts or the driver lifting eyes.
The complete pumping unit must be handled
with care. Do NOT pass the lifting slings through
the lifting eyes on driver.
D. Coupling
The coupling should NOT be reconnected until
the alignment has been completed. Align
coupling using a dial indicator to attain more
accurate coupling alignment. Refer to Figure 5,
Coupling Alignment.
Proceed as follows with parallel alignment:
NOTE
The corrections, which are made to the
alignment in one direction, may affect
the alignment in the other direction.
Angular and parallel misalignment are
corrected by means of shims. The shims
are placed under the driver mounting
feet to align the coupling. Refer to
Figure 6, Adjusting Alignment.
1. Check the parallel misalignment by
fastening the dial indicator to the pump
half of the coupling.
2. Set the dial on the indicator to zero
and rotate both hubs 360 degrees. With
the dial indicator needle against the face
of the other hub, take indicator readings
at four points, 90 degrees apart.
