TASK 71-00-02-400-009 (A1/A5-PPBU) - Install The Hydraulic Pump And Filter Assembly, Installation-009
General
For lockwire data and procedures refer to SPM TASK 70-42-05-400-501.
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.
For standard torque data and procedures refer to the SPM TASK 70-41-01-400-501 and the SPM TASK 70-41-02-400-501.
Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-077 APPROVED ENGINE OILS unless other lubricants are referred to in the procedure.
Lightly lubricate the threads and abutment faces of the hydraulic system tube/hose nuts, unions and couplings with the hydraulic fluid used in the aircraft hydraulic system.
To identify, lubricate and install seal rings refer to the SPM TASK 70-44-01-400-501.
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.
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.
Transportation covers/blanks must not be removed until immediately before installation of the components.
