5. CORRECTIVE MAINTENANCE (REPAIR)
This section describes the removal and replacement (as required for maintenance and repair) of
all booster pump components. To completely disassemble the pump and gearbox, follow the dis-
assembly instructions in the order which they appear in the text. At any point in the disassembly
process, the pump may be reassembled by following the appropriate portion of the installation
instructions.
Disassembly of the pump and/or gearbox is a major undertaking that can remove a pump from
service for a considerable period of time. Gaskets must be replaced to ensure the pump is fully
operational when returned to service. It is never permissible to reassemble the pump without
installing new gaskets. Hale Products supplies repair kits designed specifically for each pump
and the gearbox. Other parts can be ordered by calling 800–533–3569 (Hale Products Custom-
er Service). NOTE: Using your pumps serial number and the Hale website (or Customer Service) is
the best way to ensure you receive/utilize the correct replacement parts for your pump. The de-
scriptions of the maintenance levels and how each kit supports the maintenance along with the
general contents of that kit are provided in paragraphs 5.2, Maintenance Level 1 (see page 48)
thru paragraph 5.6, Miscellaneous Maintenance (see page 49).

Troubleshooting
To troubleshoot the system, locate the SCR table listing the indicated SYMPTOM, verify the asso-
ciated CAUSE (verify ALL if multiple are listed) and perform the associated REMEDY (or reme-
dies).
The SCR tables assume a single fault and the SYMPTOM, CAUSE, and REMEDY columns have
been listed in a hierarchy order. If multiple faults exist, repeat following the table using multiple
passes unless the REMEDY is always the same and does NOT remedy the symptom. When this
occurs contact Hale Customer Service Technician Department for further assistance by calling
the Customer Service Number: 800–533–3569 with the following information.
•
Pump and Gearbox ID plate (MODEL NUMBER and SERIAL NUMBER) (Refer to Section 2.2,
Pump Specifications And Numbering, in the Hale OIM manual (FSG–MNL–00183) for serial
number locations, model number definitions, and major pump features.)
•
Observed symptoms and conditions under which the symptoms occur.
Therefore, treat each SYMPTOM as the result of a single CAUSE, trace through the SCR table un-
til a single REMEDY is indicated. Perform the REMEDY, and then check the system again. Deter-
mine if the same SYMPTOM exists, a different SYMPTOM is now indicated, or no symptoms exist.
If the original symptom persists and no other symptoms are indicated, contact Hale Products at
800–533–3569 for assistance.
