FE Technical Forum / Re: 3G alternator with single v-belt and no squeal
« on: July 16, 2018, 02:08:15 PM »Just another reason why I avoid tacos With that aside I had to put a double pulley from Summit on my F100 to gain charging traction, I'm only seeing about 1/3 diameter contact at the pulley so 2/3 total on the two belts. Stopped the squealing but the hardest job I had in the process was "matching" a set of belts. I'm running 1 Gates and 1 Dayco I shopped to fit. Two of the same part number from the same lot by the same manufacturer weren't even close to the same length. Could have ordered a matched set but where's the fun in that?Nicely done. All my 3G installs use a 6 rib belt. No problems even when racing.
Not to sidetrack this post, but which pulleys are you using? I'm using a double v on my 428 and it will definitely squeal if the battery is low and the alternator is charging at full power. Case in point, left the fans on manually on accident while eating tacos. Post taco engine started...barely, everyone got to listen to my belts sing down the block.
