<DIV><FONT face=Arial size=2>Dave, if you have a stainless bearing in your hand,
remove both seals clean all the grease out with mineral spirits not gasoline
coat it with mobil 1 or some after run oil, and </FONT><FONT face=Arial
size=2>install it, if the bearing in the motor is as standard steel one, it will
probably go when you least want it to like mine did at a contest. I have
</FONT><FONT face=Arial size=2>replaced all my engines with the
stainless and probably have 75 runs on one and it actually feels smoother the
more I run it, also someone had mentioned the ring going on the OS 140 in
about 300 flights well my</FONT></DIV>
<DIV><FONT face=Arial size=2>older engine started to sag on long up lines at
approx 300, replaced the ring and cleaned the sleave and it runs like new
again.</FONT></DIV>

<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>I was wondering if when changing the rear bearing
on my 140rx if I should leave the seals in the new bearing or take them out.
also I was wondering at what point do you decide to change the bearing. the
bearing in my engine seems to be very smooth but is starting to sound louder
than it used to.</FONT></DIV>
