First in a new member. Im from Sweden.
I own and fly JR helis.
I got a ergo 60 and a ergo 30.

now to my question.

On the ergo 60 I have a probleme with the clearence between the main gear and the bearing that hold the cluth.

The main gear touch the bearing flare on the clutch.
I must use 2 or 3 shims between the main gear and the lower bearing on the main mast to get clearence.
Why is this? And is it bad to use shims?

Sorry for the bad english.

Best Regads

no one.. geee. :/

Hello, I had the same thing with a Z-230 JR- Gasser. One shim was all I needed. No problems since. WLJ

with one shim i got about 1mm clerance. Is that enough?

Thanks for your help

As long as its not touching. I flew for a while without the shim. No real problems. A little white dust is all. It wore enough to clear, but I wanted it to be just a little better. WLJ

ok thanks
