Help ! My Tail wheel suspension Jack (Cylinder) slowly goes down. I have stripped
and cleaned it and found quite a lot of oil inside . Is that correct ?
Where can I get a rebuild SEAL kit from ?
Must be Nitrogen or can I use AIR ?
I have pumped it up and put it in water but cannot see any bubbles leaking..very
odd
Any help advise , much appreciated especially as to where I can get a rebuild kit
from
Thanks

Try West London Aero Club. They have bushing and spring kit that restores the functionality
of the strut. I am not aware of a seal kit for the unit not saying
one could not be fabricated if there was enough demand.

I just found a local hydraulic cylinder repair shop in town and brought in my tail
wheel strut seals and found a match from their bench stock. I used ordinary
air when I refilled it. That was 2007 and it has been working normally since.
I think total cost was $5. Jj

The hydraulic cylinder repair shop literally brought out a box full of seals and
him and I just rummaged through them until I found one that looked and felt
the same. Not scientific I realize or official YAK part or near enough $$$ but
it's the way I roll and again, trouble free now 5 years. Jj

My Wilga seems to run a bit hot.. . most likely due to 85 knots in
cruise... However, I flushed the oil cooler with some fuel and was shocked
at all the gunk that came out. Now it runs MUCH cooler - I use the oil
cooler shutters to keep the oil in the higher temp range in all OAT ranges.

| Subject: | Re: High oil temp |
All,
About a year ago I set up to flush oil coolers because of the rising
replacement cost and the poor service I received from the oil cooler folks
here on the west coast. I first bead blast the case to remove all paint,
then solvent flush, and follow up with high pressure hot water to rinse. I
seriously doubt that they are 100% clean and as effective as a new one but
judging by the incredible amount of gunk I get out of the average cooler
they should be vastly improved.
If you need further info please contact me off list.
Best,
Doug

| Subject: | YAK 50 tail Wheel jack Cylinder |
While we are talking about this tail wheel oleo ..... My seals leak a bit as
well. Not real fast, but they leak. The idea of using seal replacements from
the local hydraulic repair shop is a cool idea, but ... also too.....
One thing I have found is that in some cases you do not need an adapter that screws
down onto the fill valve and pushes down on the Schrader like fitting when
filling the tailwheel oleo. If the air pressure is high enough, it just "goes
in anyway".
So, after the oleo is all fixed with new seals, you could simply attach a FLEXIBLE
hose to the fill fitting, and then have a Schrader valve on the other end
mounted into (on to?) the access panel. Kind of like what is being done now
(more or less) on the actual aircraft external air fill port.
One just puts a hose on there, pumps in some pressure and Voila ... the oleo is
now re-pressurized.
Instead of:
Taking out all the screws.
Removing the panel.
Taking off the fill port cap on the oleo.
Screwing on the special fill tool.
Screwing down the fill tool Schrader valve "opener"
Applying air pressure, filling oleo.
Reverse all this and then put it all back together.
Just an idea. Never tried it. (You listening Jan? :-)

If you want to get an oil cooler serviced (cleaned), this place does great work
and also does vintage stuff like Mustangs etc. I used to use them every time
a racing engine blew up on the race cars.

I don=99t know if Yaks are the same, but on our CJ, we removed the v
alve in
the Schrader fitting on our external fill port 15 years ago (someone
thought it would turn into a lethal projectile if it blew out). A one-way
,
internal high pressure valve prevents air from escaping. YRMV.

While we are talking about this tail wheel oleo ..... My seals leak a
bit as well. Not real fast, but they leak. The idea of using seal
replacements from the local hydraulic repair shop is a cool idea, but ...
also
too.....
One thing I have found is that in some cases you do not need an adapter
that screws down onto the fill valve and pushes down on the Schrader like
fitting when filling the tailwheel oleo. If the air pressure is high enou
gh,
it just "goes in anyway".
So, after the oleo is all fixed with new seals, you could simply attach a
FLEXIBLE hose to the fill fitting, and then have a Schrader valve on the
other end mounted into (on to?) the access panel. Kind of like what is
being done now (more or less) on the actual aircraft external air fill por
t.
One just puts a hose on there, pumps in some pressure and Voila ... the
oleo is now re-pressurized.
Instead of:
Taking out all the screws.
Removing the panel.
Taking off the fill port cap on the oleo.
Screwing on the special fill tool.
Screwing down the fill tool Schrader valve "opener"
Applying air pressure, filling oleo.
Reverse all this and then put it all back together.
Just an idea. Never tried it. (You listening Jan? :-)

Just remember, if you are using pressure to open the Schrader valve, it
will function as a pressure reducing valve. If it requires 150 psi to open,
then the pressure on the downstream side of the valve will be 150 psi less
than on the upstream side of the valve. If you need 1000 psi in the oleo
and you use 1000 psi nitrogen without using something to mechanically open
the Schrader valve, the pressure in the oleo will be 850 psi.

| Subject: | Re: High oil temp |
Gord's airplane has the prototype oil cooler set-up which is different (looks smaller)
than the stock 50s...
If they changed the design for the next 300 airplanes, that might be why.
Just my 2 cents.

Mark is absolutely correct: reservicing without a schrader valve works
well. I've done it several times.
About the seals: indeed it is possible to find replacements in an ordinary
shop. A friend with a Yak 50 had the seals in the tailwheel oleo replaced
by X-shaped quad rings from such a shop.
But he also had the cylinder honed because there was some corrosion. Since
then (several years) he had no problem anymore.
I tried the solution with the spring replacement a few years ago. But
IMHO, this is too hard: it hammers too hard, the spring inside the oleo,
so you risk hammering the rivets loose.
So I went back to the oleo with nitrogen.
But occasionally I have to fill with nitrogen. So next time, I'll replace
the seals with quad rings.
