Alternator Belt
by Andrew Foster » Sat Mar 05, 2011 6:08 pm
At what interval would it be prudent to change our alternator belt on a 61 250. It's been about 8 years.
Thanks
Andrew

I'd say any time it fails, or the prop is already off.

I would also add it is time to change anytime it is obviously compromised, shows cracking, or has excessive wear. In the case of excessive wear, it is a good idea to find out why as well. It can be a good indication of other problems such as bad bearings in the generator/alternator, or a misaligned or broken bracket. Short of these, and what Don said, there is no change interval that needs to be followed.

When you do change it, suggest you go to Nat'l Air Parts of America (NAPA) to get the replacement.
Good luck, Don

Don't go to NAPA, go get a good "Gates Green stripe" or you will be removing the prop for a belt change way before you should have to.....I went through this when I went to a 3 blade & was trying to find the "proper" belt which doesn't exist anymore. The original part number will cross to a Gates number so it is legal, however I found that the "heavy belt" will not quite fit. When it comes to belts & hoses...buy cheap, buy often.....

Gates is indeed the one you want. Guess I assumed you get that at napa.
Good luck, Don
