General
This TASK gives the procedure to install the LP/HP fuel pump to the engine.
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 item number.
Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-077 APPROVED ENGINE OILS, unless other lubricants are referred in the procedure.
For the torque tightening procedures, refer to TASK 70-41-00-400-501 and TASK 70-41-01-400-501 .
Special torque data and assembly tolerances are included in the procedure.
Special torque data is identified with the symbol * after the torque value.
For the lockwire data and procedure refer to TASK 70-42-05-400-501 .
To identify, lubricate and install seal rings refer to TASK 70-44-01-400-501 .
For the data on the electrical connectors refer to TASK 70-43-00-400-501 and TASK 70-43-01-400-501 .
Make sure that there is a minimum distance of 0.500in. (12.7 mm) between the harness and an adjacent sharp edge; a part which can move or system with a flammable fluid.
The engine must be isolated from starting air supply, fuel supply and electrical power source while you do this procedure.
