<VV> Ceramic Bearings ...Why?

[Mikeamauro at aol.com]

"...I haven't changed a blower bearing for years even though I'm running  
three Corvairs...
 
I, too, have three. My Corvairs are daily  transport--including long trips. I 
also work on others, so I've changed a few  failed bearings; I also change 
blower bearings anytime an engine gets  rebuilt. "Me thinks," if I can spend a 
few extra dollars for piece of  mind, and to avoid ever having to tear the top 
of an engine apart to change  one part, I'm gonna' spend the few extra 
dollars. As previously stated, I've  already found a direct replacement ceramic 
replacement for Ray Sedman's  replaceable core unit (I'm running that one in a van, 
and the  conventional bottom bearing developed a "tick" requiring 
replacement). A  hybrid replacement bearing, for the replaceable core application, is 
about $24  vs $5 for the standard steel ball unit. For two bearings, that $38  
extra; I guess I'm an odd Corvair owner (and some of you have  commented as such 
:>), but I'm willing to pay the few extra  dollars. Once we know price and 
availability, then others came make up  their minds about what they prefer to 
do... heck, maybe ceramic bearings are not  available to replace our OEM parts, 
then this conversation is moot. Again,  if someone knows the bearing ID 
numbers for the idler and the early and late  blower bearings; please send same and 
I'll research. Thank you.
