Thanks for the kind words.
And I'm one of those that did have issues with slipping belts until I installed a dual-groove pulley. However, it may just be that my large case 1G simply had more mass to move, so when it was under heavier loads, even just the usual 30-35 amp load after startup, it was just too much for the traction of the belt.
You can only tighten a belt up so much before you start overloading the bearings, so I opted for the dual groove instead. With no power steering, it was a no-brainer.
I got mine from Ford for about 4 bucks, but you can probably get them at any auto parts store that's willing to order one up from one of their suppliers.
Perhaps with the slightly smaller (lighter too?) spinning parts in a 3G, fewer people have the problem.
Don't know, but it sounds plausible.
It's probably one of those other things we should stock, but the overall demand would be so low it would be hard to justify. Especially when it won't work for most people right off the bat.
What I mean by that is, with the commonly used dual groove/sheave water pump and crank pulleys, it would be hard to get two belts on the alternator if you also had power steering. Which more and more Broncos do these days.
So it's a catch-22. Good idea, but hard to implement in many cases.
A possible alternative in those cases would be a larger diameter "racing" pulley. Bigger means more belt contact area for more traction. The trade-off is that it spins the alternator slower.
However, with the very high output of even a stock 3G at lower rpm, it seems likely (to me anyway) that it would not lower the output potential enough to be a problem.
Anyone have experience with a larger V-groove pulley on a 3G yet?
