inboard area of the hydraulic override cylinder install pipe plug into the vacant port
hole. NOTE: Use pipe dope on the bleed pipe plug.
3.1.2.7 When hydraulic fluid appears at the vacant bleed plug port hole located in the
outboard area of the hydraulic override cylinder stop the pump motor and install
pipe plug into the vacant port hole. NOTE: Use pipe dope on the bleed pipe plug.
3.1.2.8 Disconnect the pump motor from the M11 pump hose.
3.1.2.9 Connect the M11 pump hose to the fitting on the reservoir outer end cap (10-10).
