<DIV>Don,</DIV>
<DIV> </DIV>
<DIV>You are most likely right about this. I just happened to have bearing
failure about the time I switched. I left the seal out of the replacement
bearing and it only lasted 20 flights. Seals are in the new bearing(it has
about 50 flights on it now)and when this one goes it WILL be replaced with a SS
bearing.</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>

<DIV>There is a lot of Magnum fuel used on the West Coast with no noticeable
difference in bearing life. Most of the people using the OS140 engines
have switched to stainless bearings and don't worry about bearing failure
after 30-60 flights anymore. The stock bearing failures were occurring
regardless of fuel type. The stock bearing appears to be very
susceptible to corrosion even if you run the engine dry after flying or not,
whether you use after run or not. Stainless bearings made that problem
go away and the life of the bearings is typically in excess of 100 flights
with most going over 200. I get my stainless bearings for the OS from Jerry
Budd at Budd Engineering (aka Rusty Freid ;-).</DIV>
<DIV> </DIV>
<DIV>YS 4C don't seem to wear out the rear bearings as quickly and we have
people out here with over 500 flights on YS engines/bearings with no
noticeable wear problems using Magnum. Having said all that, doesn't
seem to be a problem out here. Lot of Magnum shipped to the Chicago
area, and the Northeast (can't remember exactly where).</DIV>
<DIV> </DIV>
<DIV>Guys, hope this doesn't launch a tirade of 'this fuel is better, that
fuel is better'. Fuel usage is like discussing politics. I run
Magnum because I have had very good luck with it, have run it since it was
introduced in Denver when I lived there. There are several good fuels
out there, I selected Magnum.</DIV>
