TASK 72-00-40-450-002 HP System Module Components - Install The Active Clearance Control (ACC) Actuator, Installation-012
General
The TASK gives the procedure to install the active clearance control (ACC) actuator.
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.
The number for each radial location must be identified in a clockwise direction. These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure.
For standard torque data and procedure refer to the SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-400-501.
Special torque data is identified with the symbol * after the torque value.
Assembly tolerances are included in this procedure.
For lockwire data and procedure refer to the SPM TASK 70-42-05-400-501.
For safety cable data and procedures refer to the SPM TASK 70-42-08-400-501.
Refer to the V2500 Illustrated Tool and Equipment Manual (ITEM) Pub ref ITE-V2500-1IA for the illustrations of the special tools used in this procedure.
Transportation covers/blanks must not be removed until immediately before installation of the components.
Do not remove the special plastic from electrical connections or tube connections which are not applicable in this procedure. This will give protection from unwanted material.
Apply CoMat 10-094 ANTI-SEIZE COMPOUND, PURE Ni-SPECIAL or CoMat 10-110 HIGH TEMPERATURE ANTI-SEIZE COMPOUND to all the threads and abutment faces of nuts and bolts unless other lubricants are referred to in this procedure.
After assembly apply CoMat 07-038 AIR DRYING ENAMEL to damaged surface protection, joint flanges and attach parts. Use the correct color of air drying enamel. Refer to the SPM TASK 70-38-21-380-501.
