Subject:total seal ring end gap on 95mm pistons?
From:Damon Campbell
Date:Sun, 3 Aug 2003 16:23:24 -0700

Hello list,

I'm currently gapping the rings on the engine i am
building, and am using the non-traditional combination
of total seal rings (the second ring is gapless) and
the 95mm pistons.

First thing i notice is that the ring end gaps
specified by bently are significantly larger than that
of total seal:

upper: .035" (bentley)/ .020" (T.S.)
middle:  .035" (bentley)/ .013" (T.S.)
oil scraper: .037" (bentley)/ .015 min. (T.S.)

Now so far, the uppers and oil scrapers seem fine per
T.S. spec, but the middles, without any filing, are
coming out to about 0.019".  These are the somewhat
funky gapless ones - how strict is this number (seems
pretty strict), and what should i do about it?  Also,
why the difference between bentley and T.S.?

My final question is that i'm having a really hard
time determining which way the bevel on the top ring
goes - what is the secret method to doing this?

Thanks for any help,
-Damon
