Correct Part number for OS 140RX rear bearing needed (non EFI)

[Jerry Budd]

They are different bearings.  The EFI comes with a different bearing 
than the RX.  The stock OS RX bearing is no better than the standard 
bearing you can get from Boca.  The EFI bearing listed on the Tower 
site appears to be a stainless steel bearing with a rubber seal, but 
it is usually listed as "special order only" or something like that.

I have some stainless steel bearings with stainless steel retainers 
and rubber seals made by KSK available that have been in use by the 
guys in the Bay area, many with over ~350 flights and no problems of 
any kind (I've been told that they don't run dry, do anything special 
for cooling, use after run oil, nothing).  They aren't up on the 
website yet (probably later today or tomorrow), but they sell for 
$30+ shipping.

Thx, Jerry
