ORDERING RENEWAL PARTS; REPAIR, AND REPLACEMENT PARTS
Spare and renewal parts orders for GE turbine parts should be placed with your GE Company Apparatus &
Engineering Services Operations office.
Those components identified in the Parts Volume of your Service Manual with a Proprietary Design statement
are considered critical in design, have an affect on unit longevity and may impair warranties. Therefore, re-
placement of these components or parts within the assemblies must be monitored by the GE Company, who
may substitute improved designs.
When ordering parts for the turbine or associated equipment, refer to instructions provided in the Parts Volume.
RETURNING TURBINE PARTS FOR REPAIR/REPLACEMENT
It is important that you contact your GE Company Apparatus and Engineering Services Operations office for
assistance when returning turbine parts to GE. They can explain the proper procedures as well as supply the
required packing instructions, packing lists and shipping labels. They will also arrange to have a GE represen-
tative confirm the receipt of your parts when they arrive and explain whatever corrective action the factory
recommends.
MAINTENANCE PARTS RECOMMENDATIONS
The primary objective of the typical recommended spare parts listings is to minimize turbine downtime during
scheduled maintenance. Your spare parts stock is the basis for a well-planned maintenance program.
Spare parts recommendations are provided to support scheduled combustion, hot gas path and major inspec-
tions. To minimize downtime it is good maintenance practice to have the necessary parts on site prior to the
inspection. The gas turbine can then be shut down, parts removed, new or repaired parts installed and the unit
returned to service. The removed parts may then be inspected and a determination made if they can be repaired
for reuse at subsequent inspections.
These spare parts listings must be used in conjunction with the Parts Volume of the Service Manual. The model
list reference following each spare parts section heading, i.e., ML0512, 0701, 1214, etc., specifies the applica-
ble tab in the Parts Volume, i.e., 5, 7, 12, etc. The specific drawing and part numbers required to support the
planned inspection can then be obtained.
Using the typical recommended spare parts list as a guide, your spare parts stock should be reviewed at a pre-
inspection planning meeting. GE Company Spare and Renewal Parts personnel are available to participate in
your pre-inspection meetings to assist in planning your parts requirements for the scheduled inspection.
Note: A single asterisk (*) indicates not full quantities as called for on draw-
ings. Twenty percent (20%) of the quantities called for are listed. These
quantities should cover any hardware which may not be reusable.
Note: Double asterisks (**) indicate items are expendable (not to be reused).
They must be replaced at each inspection.
