 Posted: Mon Aug 05, 2013 10:57 pm Post subject: tailwheel oleo Yak 50 |
 |
|
Once again, all pressure gone. This is not an uncommon problem on the Yak 50.
I had it overhauled some years ago, new seals …
It worked well for about two years, now I have to repressurize again and again and the cycle becomes shorter.
So I took it out and opened it.
The seals are still good, but there's a scratch at the inside of the cylinder so no wonder the nitrogen escapes.
The scratch was caused by a tiny little screw that's supposed to block a plate on the piston, to hold the layers of seals.
The screw had a sharp edge …
This oleo is almost impossible to find. There are none available in Russia anymore, that's for sure.
I don't know if honing the cylinder is a good idea, since it's rather thin and I can't tell how deep the scratch is.
A few years ago, I tried to put a spring inside the oleo, but that's very bad: it behaves completely different and is too hard on the connection of the oleo to the tail.
My Russian inspector at that time, Sergei Makarov, said that the spring resonated and that it hammered too hard on the tail connection.
What do you guys suggest?

Jan,
Kun je geen nieuwe cilinder laten draaien of de bestaande cilinder uitdraaien tot de beschadiging weg is en daarna laten verchromen/harden??
