Common Information
TASK 72-00-40-050-001-C00 HP System Module Components - Remove The Variable Stator Vane (VSV) Actuator, Removal-010 - SBE 72-0564 (SelectOne Production Standard), Removal-010
General
This task gives the procedure for removal of the Variable Stator Vane (VSV) Actuator only for engines, which have SBE 72-0564 (SelectOne Production Standard) incorporated.
Fig/item numbers in parentheses in the procedure agree with those used in the IPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the IPC.
For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.
Apply the approved CoMat 10-058 PENETRATING OIL before the removal of threaded parts. Let the parts soak before removal.
Remove and discard the lockwire before the tube or connector is disconnected.
When electrical connections are disconnected, special plastic caps must be installed.
Seal all openings to prevent contamination from unwanted materials.
Discard all rubber seal rings removed in this procedure.
