At this point, it
appears that one of the triangular pieces of the apex seal (could not find it
anywhere) left its proper position (undoubtedly during my assembly) and got
lodged at the end (apex) of one of the rotors. May have been held their by some
combination of the corner and side seal.
Hi
Ed,
Are you saying you think the
little triangle piece came out of the slot, and was wedged flat between the side
of the rotor, and the side housing?
The rotor running clearance is
supposed to be .0047" to .010", so 2mm (.0787") seal ain't gonna fit
between the rotor and the housing, if that's what you were saying. I would
bet that you wouldn't be able to turn the engine at all if you bolted it
together that way.
OR, were you saying you think the
triangle piece of seal was still in the apex seal slot, but being pushed toward
the side of the rotor, similar to having a seal that was too
long?
In either case, the wear you would
see on the opposite side, would be from the rotor gear, or thrust
ring (whichever side that happened to be) of the rotor, since
those are raised above the side of the rotor itself. The damage
to the side housing would be similar to my oil out I would
imagine.
If the triangle piece of seal
was missing, I'd wonder if that wouldn't let combustion pressure get behind the
corner seals (particularly the side with the missing piece), and push
outward creating the extra friction. Of course I'd wonder
why that didn't happen at two places, since that apex seal is on
the leading, and trailing edge of two faces of the rotor.
Do you have any pictures of
these hot spots?
Cheers,
Rusty
