Drive Belts

[John Q. Doe]

I use O-Rings bearing the ASE part numbers as follows for the front two O-Rings:

             I.D.   O.D.    Width
AS568A-226   2.0"   2.25"   .125"
AS568A-225   1.875" 2.125"  .125"

I use the -226 O-Ring normally. However if the capacitors
are unusally stiff and lubricating does not relieve the
stiffness I use the -225 to prevent slippage. Also I do not
use the 3/32" (0.103") or 1/16" (0.070") width O-Rings as
they do not seem to provide enough surface contact area on
the drive pullies resulting in slippage.

A complete listing of O-Rings and thier respective specifications can be found at:

This site also has info on determining the size you need
for various applications.

THIS IS WHAT I USE! You need to determine if it meets your needs however.
