1. Remove the capscrews, the head and the idler from the
pump. It may be necessary to apply a slight pressure on
the drive end of the rotor shaft to free the head from the
casing. DO NOT PRY the head from the casing as this
may damage and mar the gasket surfaces.
2. Remove idler from idler pin. If the idler pin is worn, both
the idler pin, and idler should be replaced.
3. Next, completely remove the rotor and shaft assembly
from the casing by exerting pressure on the drive end of
the shaft.
4. Remove the packing nut.
5. The pump is now ready for removal of the packing or
mechanical seal. Refer to figure 3 or 4 for example. It
is recommended a new mechanical seal or packing rings
be used every time a pump is completely disassembled.
All parts should be examined for wear before the pump is put
together. When making major repairs, such as replacing a
rotor and shaft assembly, it is usually considered advisable to
also install a new casing bushing.
