    "the emergency extension lines do not in fact connect to the nose wheel's high and low pressure lines if you look at the POH"
    Not true, the POH is wrong. Check the maintenance manual or get a mechanic to run a borescope down under the heater. You'll see the extension lines.

    Did you forget about the Pressure switch or is it just me? If anyone is wondering what pressure switch is, the use of it is to shut off the hydraulic pump motors automatically when the system hydraulic pressure is too excessive.

      Good catch! I'll add an annotation to the video. Thanks very much.

    the emergency extension lines do not in fact connect to the nose wheel's high and low pressure lines if you look at the POH, When the pump runs, the fluid actually moves around the outsides of the gear. It's unable to go through the middle as drawn because that is where the teeth of the gears connect while turning. Just sayin. No worries, good video otherwise
