<VV> ALUMINIUM CORVAIR IDLER PULLEY?

[corvairs]

Ron - The design mentioned here has a strange irony attatched to it. The 
bearings used are much "weaker" (lower load rating/life span) than the 
original design bearing. But on the bright side, the design makes it 
much easier to change the bearings - which you will have to do much more 
often. To make matters worse, "quality" versions of that bearing (6203 
type) are VERY difficult to find - the Chinese production having flooded 
the market. So your random odds of getting a REALLY inferior bearing
is pretty high.

I think the original intention of the design was to make a bearing 
assembly that would be easier to change (although with the idler unit 
that's marginal anyway) AND be stronger - that is when you could get 
decent 6203 bearings......it's all changed. A good quality idler bearing 
should last 30-40 years. I don't know of a single 6203 bearing on the 
market now that will last more than a few years. This is a serious 
problem with rebuilt generators and alternators which must use the 6203 
bearings. But it is what it is.
