[s-cars] Serpentine belt tensioner bearing

[Tom Green]

Great advice, Igor.

My only addition is that the most common replacement 6203 bearing  
will be
of Chinese manufacture.  So, I listen carefully for new noise while  
doing the
durability test.  :-)

You probably had a rivet supply handy, Igor.  My measurement said I  
wanted
a 5mm X 10mm solid steel rivet.  The best I could do was a 3/16 X 3/8  
in  rivet
from McMaster-Carr.  I believe that mushrooming the head also compressed
the shaft to fill the larger hole.  Drilling to 7/32 looked too big  
to me.

The rivets only come in boxes of 100 from McMaster-Carr.  The local  
supplier
has a much higher minimum buy unless you have a commercial account.

You want to ensure the rest of the tensioner, especially the steel  
spring is in
good condition, Josh, before you extend the operating life.
