Yes, Indeed! Started putting the rotor
pieces together last night, the used side seals all give very good
tolerances. I had to change some from the slots they were in on
the old rotors, but juggling them around I could match the seal length to
the slot quite well. Glad I could as you have to trim the stock side
seals for your fit - a tedious task at best.
I was a bit dismayed to find that the tolerance
on my oil control rings wear were at or outside of specs after only 150
hours. Again, this could be accelerated wear due to ingesting
the dust around my hangar. So had to order some more.
A filter will be next on the list.
Interestingly in the basic kit you get through
Tracy, they provide a length of rubber channel tube that you cut your
corner seal rubber plugs out of.

Rotors!
Ed,
Sounds like the fun is ready to begin.

Got the new rotors today - first time I've
ever seen a new rotor - the are bright metallic
{:>).
The depth of the apex seal slot on the new
rotors ranged from 9.65mm to 9.77 mm. Interestingly the width of
the bottom of the apex slot was 1.88mm but the top was narrower at
1.778mm. I noticed that the lip of the apex seal slot had a tiny
burr of metal along it as if they were not using a sharp enough tool or
else pushing it along too fast. Or perhaps no one took the time to
deburr the slot.
Just in case any of you ever wonder whether you are looking at a
9.7:1 rotor or some other rotor, there is a fairly easy way to
tell. Lay a straight edge across the depression in the rotor and
measure from its bottom to the center of the depression, it should
measure right at 4 mm. The 9.1 measure around 7mm for
comparison. Just thought you might want to know.
