Those of
you who
are flying, how do you fill the reservoir and how often do you need
to
add hydraulic fluid to the system?
Pete,
1. Lose weight before performing each annual condition
inspection.
2. Have a "safety person" in the hangar in case you get stuck.
3. Utilize an Ace Hardware thumb-pump oil-can filled with Hydraulic Fluid
dyed with Red #2 carcinogenic dye (Oh, that's right, it is already red).
4. Add a 4' piece of discarded Tygon tubing to the oil can and place the
other end in the reservoir opening.
5. Fill to fill line - This may require refilling the oil
can.
6. With the dump valve open, Gear switch in the Down position,
have the "safety person" run the pump for a bit.
7. Check the fluid level. If low, go back to step
5.
8. Get out of the airplane and have a beer. With the Airplane
on Jacks, Close the dump valve and turn on the power - The pump should
pressurize the down side even though there is air in the system. If the
gear comes up, the wiring is wrong and your "squat" switch ain't worth
squat.
9. Defeat the squat switch and move the gear lever to up. Apply power
and watch the gear (no doors) come up and stop. If the gear goes down,
there is a great deal wrong - Wait until tomorrow and re-think the whole
thing.
10. If all is okay, add the doors and recycle.
11. Continue to recycle until the air is worked out. Re-check the
fluid level. Have a beer. Send the Safety Person home.
12. With this phase completed, undo the squat override, check that
the gear switch is in the down position and the indicator lights indicate down
and locked, make sure the wheels are on and lower the plane off the Jacks.
Voila!

PS: Unless there is one of those d*mned leaks, Just checking
the fluid level occasionally is all you will need to
do.
