Good find on the Mazdatrix aftermarket seals Rusty, I was not aware of
that. Mazda's new 2mm seal design is 2 piece (introduced in 2004 I think),
the 3 piece is obsolete. It is quite possible that Chuck got his
prior to the new Mazda design so he could have the aftermarket
parts. RWS does not furnish seals to Mazdatrix so guess
they would have to be Hurley or Atkins (same material AFIK).
FWIW, the admittedly second hand info I get here says that Hurley &
Atkins have at some point about 1 - 2 years ago changed material after
complaints of too much rotor and housing damage after apex seal
failure. They apparently succeeded in reducing it by making the material
crumble more easily but this results in even more seal
failures. Keep in mind this is hear-say based on customer
comments.
I'm also hearing negative reports on the Mazda 2 piece seals. As far
as the 3 piece seals that generate a lot of negative comment,
they are what I used for the first 856 hours, which is longer than I have used
any other seals. It takes a lot more time and samples than this to be
meaningful so do not take this as truth carved in stone. I offer this as
anecdotal data only. I currently use stock Mazda Renesis seals because RWS
(nor anyone else) makes them yet.

Stock seals in 2mm are three piece which
are junk but the stock 3mm seals are two piece and they are very good
quality.
Dave were they 2 or 3mm seals ???

Hi
Ken,
I think we
were talking about Chuck's most recent problem, not Dave's.
As for the
seals, IIRC, Mazda made 2 and 3 piece 2mm seals over the years. I
can't recall which years though. Looking at the Mazdatrix site, they
list 86-95, 2mm, steel 2-piece Mazda seals. I don't see a listing for 3
piece (maybe because they're junk). They also list aftermarket
2-piece 2mm seals as well, so if he bought them from Mazdatrix, they could
have been non-Mazda seals.
