Removing the shaft nut
It is important to ensure that the shaft cannot rotate while the shaft nut is removed. If the motor is fitted
to the pump, its torque should be enough to secure the shaft. If it is not secure, uncouple the pump from
the motor and secure the shaft using a tommy bar or a spanner handle between the spider castellations
on the drive shaft. Alternatively, a well-padded wrench can be used on the shaft and the key or keyway.
