Front Alternator Belt, Part #2904, new source.

Builders:

In our conversion manual, (http://shop.flycorvair.com/product/conversion-manual/) , The front alternator group is #2900, and the belt itself is Part #2904.  In the manual we specified a Continental AVX10-710 belt. A number of people have asded about another source, as Conti, now lists their number as obsolete, and people had a hard time at their local auto parts store getting an interchange.

.

The issue is that most countermen don’t know enough about the parts they sell. Conti is a German company, and the “10” in their part number is 10mm wide, and in the US that is a 25/64″ width belt. “710” is the pitch length in mm’s, which is pretty close to 28″. The belt pictured below, available from any NAPA store, is a valid interchange. Please write this note in your conversion manual.

Above the correct replacement belt.  This has been verified to work on a Gold hub, with a Front Alternator bracket set and a front alternator.

About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.

    Hey William,
    Thanks for this. I had chased down numerous leads for this to no avail. I was almost to the point of having to learn german and befriending helga, to swipe the one off her porsche. Getting the one at NAPA will be much better.
