Bayou Bert · #1 10-28-2013, 10:31 AM

Could someone direct me to where I can find a chart or something
that list this sizes of the belts.
I have a carquest belt I would like to switch to a Lycoming belt but
can't find anything that list the lengths.
Any help appreciated.

What numbers are on the Carquest belt ? They should translate into width and length .

Hi Tom I have the numbers on the Carquest belt, I can't find spec
numbers for Lycoming. I bought wha I thought was the right belt but
the alternator now hits the cowl. I need to get the belt on before I put
CS prop in place.

I know you're just looking for the part number, but why buy a "Lycoming" belt?? They don't make belts, but reputable manufacturers such as Gates, Goodyear, Maurey, Dayco, etc. do.

It depends on what size pulley you have on the ring gear and the size of the pulley on the alternator.
Here is a cross reference link.

I use the Gates XL25-7360 on my O-360AIA.
