   Why not change the present alternator to 24 volts and use a smaller 12 volt automotive alternator to keep the start batteries charged and 12 volt items supplied.

I finally found the takeoff. I didn't realize that one ear was broken and that the adjacent one has a crack. I think it is usable with washers, but I cant say for sure.

That looks like a blower driven accessory drive

I believe you're right.  I bought if for my 4106  but never opened the box until about a year after I sold it. I can't remember much about it.

There are numerous additional parts but I can't get the photo small enough to post it.

So how does this piece work?!  Does it add onto the blowers drive and add a pulley to it for something like an alternator?

Was thinking about doing the swap to a 24v gear driven alternator for the house side and a smaller 12v belt driven alternator for the starter side. But still comes down to being able to connect something belt driven!

Luvrbus,
what does the ac shaft from the torus that you have look like? Don't really know what the set up used to be like.

Sorry for the noob questions! Still learning!

Yes. The pulley is shown on the left in the first photo. I expect Clifford can tell you more than I can, since I never installed it.
