Q&A: Alternator Belt Replacement, Fuel Burn, Alternatives for a New Spinner

Hi Steve,

I’m looking for the proper dimensions of an alternator belt—primarily the [correct] width—and maybe the original manufacturer’s name and part number. 

In about 180 hours since January of last year, we have replaced three belts on my 1981 Cessna 182 Skylane and are trying to discover the problem. 

So far, we’ve been looking at alignment, pulley smoothness and whether we have the proper belt. Do you have other ideas?

Thanks,

Lyle
