OS 61 Bearing Replacement Gasget Question.

Hi All,

I am in the middle of replacing the bearings on my OS 61 .  When
dis-assembeling, the paper gasket got broke.  Has Anyone used just hight
temp  RTV Silecone instead of this gasket?

If not then any other suggestions would be great.

Thanks
Don

If you're talking about the paper gasket on the backplate, yes, you can use
hitemp silicone there.

 It is possible if it is just torn to use it again.  If it is a simple tear,
use the red stuff on the EDGE of the mating surface only as you do not want
the excess inside the case.  Makes for other *** problems.  Or if
necessary, get a new gasket.

If you cannot find a new gasket, make a quality gasket yourself.  Coat the
old gasket with light oil and then lay the old gasket out on a brown paper
sack.  Make sure it is flat and come back a few minutes later and you will
have an oil soaked gasket ready to cut out with small scissors or a #11.

Ok guys i learned this trick from an old autoshop teacher.
you take the gasket material and lay it on the surface it's going to go on.
next you take a small ball peen hammer and tap around the edges just enough to
cut through the gasket without deforming the surface you want to seal.
it makes a perfect gasket every time.
with aluminum you have to be carefull not to hit too hard or you may distroy
the flat surface you want to seal.
i have used this to make head shims out of beer cans for several engines and
they came out perfect.
you have to pick the gasket material for the intended use, for cox .049's i use
the waxed paper from inside a cerial box, for larger engines i use brown paper
bags, for even larger i use the cerial box or a playing card.
all that matters is that it has to fit right and be thick enough to seal
properly.
the rtv idea is a good one, but you often break the gasket when you take it
apart again, i usually just use some oil to get a good seal.
I hope this makes life a little easier for you.
Keep them flying!

Hi Guys,
Thanks for the information.  I did manage to find a piston ring and a gasket
kit from "Great Hobbies" out of Prince Edward Island Canada.  Being on the
other side of the country in BC, it's just going to be a waiting game for
the parts.  I do hope express post will get here by next Wednesday.

It seems that my OS 61 is from the 1979 Era and mostly every other model has
been discontinued with respect to the Ring.  However OS is still making a
heli unit that uses the same ring in the 61 size.  Lucky I guess,

Thanks again to all.

Cheers
Don
