Pump Shaft Installation
Flex series single stage booster pump pump shafts vary by model and GR yet appear similar
without detailed examination. It is therefore important to verify the replacement pump shaft prior
to installation. With the exception of the RSD (which is NOT available with the 3.74:1 GR) Flex
series booster pumps require a different pump shaft when configured with the 3.74:1 GR. See
Figure 48 for an AP or a CBP and Figure 49 for a MBP or RSD pump shaft differences detailed.
Note drive side shaft diameters and the difference in spacers.
