Subject: [FlyRotary] front cover
o-ring?
Greetings,
I went out to finish
putting on the front cover, but didn't get far. Attached are several
pics of the front housing where the o-ring goes. One shows just the
housing. One shows the old o-ring and nylon backing washer.
The other shows the washer that came in the overhaul
kit.
Previously, I had the
thicker o-ring with backing washer, and the front cover used a
gasket. The kit instructions say to not use the gasket (and none is
included), since the included o-ring is thinner. The
instructions call the nylon washer version 89 and later, so it appears
that's what I have, though I thought I had already determined that my front
housing was an 87-88. Just another mystery.
Anyway, the kit
instructions say- "Choose the correct o-ring for your application: small
diameter for 86-88 models, larger diameter for 89 and later". The
o-ring in the picture is the only one I see, except for a tension bolt o-ring
that wasn't needed. As you can see, this doesn't fit the milled recess
in the housing, though I suppose it might still work OK. In the video,
the o-ring that Bruce installs fits in the outer diameter of the recess.
Is this the correct o-ring, or the "small" one that should go to the 86-88
model? It just doesn't look right to me, and this is fairly
important. Worst case, I could always get a gasket and put it back
the way it was, with the old o-ring.
Thanks,
