That was most informative Snowmann. Thank you.
So, would you recommend that even if a bearing outfit can numerically match the OEM belt, not to use their product?
Along with the power transmission product suppliers, even Gates and Dayco have their "equivalent" cross reference. These X-references are done with an automotive type criteria. That is, if they are close in length (close in automotive terms is sometimes not close for other apps) and the section is close (4L and HA for example), they classify the belt as equivalent in a X-reference. Not really a quality comparison.
It may get someone by in a pinch. I've done it before. If one cannot wait to order a belt, and a snowstorm is brewing, it sure beats a shovel and a heart attack. Also, for some of the older machines that no longer have product support or service parts, this is the only option there is (trial and error with off the shelf belts that is).
