Subject: [FlyRotary] Engine Apart
I finally took the engine apart yesterday.
As expected, there was not coolant left in the engine - it all boiled
out! The rotor housings were very toast, having melted around the
leading plug hole. They also shrank about .015 in that area and left an
aluminum coating on the inner surface. Even one of the tension bolts had
to be pounded out because the passage melted shut! The tefflon o-rings
were intact except for a 5-inch section through the hottest area of
combustion.
All apex and side seals were still in their place. The apex seals
were a little damaged from going over the melted aluminium.
The bearings are a little rough and will have to be replaced, but the
e-shaft is undamaged. The rotors are usable. The end housings all
got severly blued in the hottest area. Does anyone know the significance
of that? Can they be used?
There were no broken tension bolts or leaks in the cooling system big
enough to find. So basically enough of it squirted out the top to expose
the water pump, then melt-down occured.
Live and learn I guess.
