5.6. Miscellaneous Maintenance
Miscellaneous maintenance consists of procedures to replace pump and/or gearbox compo-
nents that typically do NOT fail under normal operating conditions. The procedures cover all ma-
jor components that typically constitute a complete overhaul of the pump.
Before attempting a miscellaneous maintenance repair contact with Hale Customer Service (see
Section 5.1, TROUBLESHOOTING) is recommended for FAST Centers and required for an end-
user. (Hale pumps require ONLY trained maintainers perform miscellaneous maintenance.) This
level of maintenance is typically considered shop maintenance, in which a complete tear down
and removal and replacement of select major parts is required. Especially when this level of
maintenance is required the repair must be conducted by a FAST Center or an OEM (supported
but NOT typical). The Customer would need to be prepared to provide ID plate information (COM-
PLETE INFORMATION FROM ALL ID PLATES) for the affected pump and gearbox.
Unlike level 1 or level 2 maintenance there is no kit to support a complete overhaul of the pump.
With this type of maintenance individual failed components must be ordered. The cost of individ-
ual major components and the associated labor for replacing them added to the subsequent re-
quired pump testing may be prohibitive. Miscellaneous maintenance procedures are included to
replace all major components (cooler parts, shafts, inducers, impellers, clearance rings, gears,
etc.) however when Hale Customer Service (see Section 5.1, TROUBLESHOOTING) is contacted it
will evaluate the cost associated with the requested components and advise if a replacement
pump (including a new warranty) would be more cost effective.
