That's quite a different use

If you're not living on the edge you're taking up too much space!

Yeah - that's right. :-)
Maybe we should start a thread for all the non-vehicle uses of the '460's. I have heard of wood-chippers and irigation pumps. Thanks to the good help I got from the members of this forum, my project turned out well and there are now three other winches being built in Europe using a '460.

The only mods I had to do was enlarge the upper mounting through bolt hole slightly to accept the SAE size bolt, change the pulley from serpentine to "V" pulley, they interchange from a 1G (externally regulated)to the 3G(internally regulated). The brackets I used were originally for a 70-100amp large case alternator. The 3G holds 14.5 volts at idle with all acc. on including A/C. I can buy these from a U-Pull-it yard for $15-20. I hope this helps in any way, Todd
How does the physical size of the Taurus alternator compare to the "large case alternator"? I've got the latter and I'm trying to use the CVF Racing low mount alternator bracket. Unfortunately there's not enough room between the engine and the frame rail (West Coast Cobra) for that large case alternator, so I'm looking for a smaller physical alternator in the hopes I can fit that in the limited space.

When you re-wired I'm assuming you removed the external voltage regulator and essentially re-routed the wiring to the alternator. Correct?

Thanks in advance.

The 130 amp large case 3G(#7765) is smaller than the large cased 70-100amp 1G alternators(side terminal), but JUST slightly larger than the smaller 50-65 amp 1G "regular" alternators. The 3G and 1g alternators seem to have just about the same "installed" depth. Here is some pics I found online, hope they help:

Yeah, it's a hybrid...It burns gas and tires.

No matter how good she looks somebody, somewhere is tired of her sh#t.

Thanks. The photos helped, and I've been able to track down a few dimensions:

Diameter / width of alternator case (not including mounting ears):
1G small: 5.51"
1G large: 6.25"
3G small: 5.20"
3G large: 5.90"

Length / depth (front of mounting spigot to back of case / bearing housing):
1G large and small: 4.90"
3G large and small: 4.50"

Mounting - centre to centre:
1G small and 3G: 6.93"
3G large: 8.11"

Compared to my 1G large case / frame, the 3G small frame alternator is 1.05" smaller in diameter / width, 0.4" shorter and the body of the alternator mounts 0.59" (1/2 of 1.18" difference between mounting ears) closer to the mounting spigot. All of these tighter dimensions will help with my clearance issues. The small 3G is 95 amps and my current 1G LC is rated at 100 amps, but I've also seen charts that show the 3G producing far higher output at idle and lower RPM than 1G, so I don't see any issues there.

Anything I'm missing?

Thanks.

Great info on the above dimensions . There are 2 different large case 3G alternators using the pivot mount, I use the one on the left that has 7.00" bolt centers, easily fits the stock 460 alternator bracket(on my application anyhow). The 130 amp large case 3G puts out about 80-85 amps at idle(1800-2000 alternator rpms) and about 160 amps at "full tilt", so they do have a built in amperage "headroom". Hope this helps.
