GE Vernova heavy-duty gas turbine spare parts — major and minor groups

These component groups are described in GE Vernova heavy-duty gas-turbine maintenance literature. Combustion arrangements and parts differ across B, E, F and annular/silo fleets. This grouped reference does not assert that every item is installed on every model; aeroderivative LM machines require their own parts documentation. No inspection intervals or unit-specific replacement instructions are prescribed here.

Major and minor are navigation groups on this catalogue page. They do not define an OEM inspection interval, replacement interval or safety-criticality classification. A small item can still be critical to turbine operation.
