NOTE
Hydraulic tubes are secured using straight thread connectors. Main hydraulic hoses are
identified by their large size and the fact that they have shut off valves in their lines.
Many tubes and hose connections used on the CBPS system contain an O-ring to prevent
unwanted escape and loss of hydraulic fluid. O-rings, identified in Appendix E, are
mandatory replacement parts.
Tubes or hoses may have to be loosened or removed completely when performing
maintenance in the ECU.
A small amount of hydraulic fluid will be released when removing a tube or hose. Drain
excess fluid from hose or tube into cup or container. Clean any spillage with rags.
Remove/disassemble only to the extent necessary to remove or replace defective
assemblies/components. Use standard maintenance shop practices/procedures.
