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.
