 Posted: Tue Aug 09, 2016 2:22 am Post subject: Landing gear legs |
 |
|
Guys
Let's pull out your bag of tricks ...
1 - I am having difficulties inserting the L & R main gear legs, and I don't
want to use any technique that will ruin something.
Will it be because of the high temperatures here (over 96ºF)?
Can I use sand paper on the inner surfaces of the WD-1021 and on the outer
surfaces of the legs?
Should I use some kind of lubricant?
In one word, are there any tricks to facilitate the insertion of the main
gear legs?
2 - Regarding the Nose Gear leg, I'm having trouble to thread the MS21025-24
big nut into the spindle of the WD-1017 Nose gear leg.
I see no scratches in the thread or on the nut, so what is the trick here?
3 - Still in the nose gear leg, despite trying to do what is indicated in
the manual, I am not succeeding in compressing the 4 "Mooney" rubber
dampers, in order to install the upper bolt through the gear link.
What technique did you use?
Thanks
Carlos

As a rule, never put two pieces of metal together (like gear legs into
weldments) without grease. The grease will help on the install, and the
grease will prevent the two piece of metal from fusing together with
corrosion. Any standard grease is fine. Same goes for when you install the
wings to the fuselage.
On the bolt and nut - try a new bolt and nut.
On the nose gear dampers, it helps if you have the engine mounted. Chock
the wheels and use a long ram jack to GENTLY push up on the tail. Use a 2x6
or such with a lot of padding between the bottom of the tail and the jack.
The alternative is to get a heavy duty ratcheting cargo strap and run it
between the top of the engine mount and the nose gear, and start ratcheting.

As Carl said, up grease in all of the bearing surfaces. That should help putting them together.

I have never had trouble getting them on. Are you sure you are using the right nut?

There are a couple of ways to do this. The easiest is with the engine mounted then putting a ratchet strap from the engine to the nose gear fork area (anywhere it can hold on) and tighten until the bolt fits. You can also lift on the tail, but you will likely lift the mains off the floor before the bolt fits. We have also run a ratchet strap from an intersection of tubes on the engine mount to the gear leg to compress them.

Carl (we're probably twin souls...)
Thanks for the tips, especially the one to compress the rubber dampers.
As for the big nut not threading, it's not on a bolt, it's on the thread in
the nose gear leg bottom tip, so I can try a new nut (difficult to get from
Oregon to Portugal...) but not a new nose gear leg

Ok - so perhaps the first thread on the gear leg got messed up. If you
never chased threads before, ask someone to come over and carefully dress
the first thread.
If you cross threaded the nut, then get a new nut.

I would infer from your questions that you are trying to do some of the
gear steps out of order. With the mains you need to ensure the socket
interior and the gear leg are smooth, with no rough edges. Use medium to
fine sandpaper on rough areas, or Scotchbrite. You will need grease.
On the nose gear nut, examine the threads carefully. Something is not
right if you can't get it started by hand.
The donuts do not get compressed until you have the plane on the gear.
You need to be able to lower the nose gear leg enough to insert the
strut into the bracket, and bolt the lower end. The compression is only
done with plane on the gear, to secure the cap at the top of the strut.
As Carl indicated the easy way is to use an aircraft jack on the tail
tiedown ring (or jack point inserted in place of the ring is safer).
Slowly raise the tail and keep checking until you have just enough to
install the retaining bolt.
Oh, and yes, the shock disks are in fact the part number used on all
three Mooney landing gear.
