Is there a way to add the accessory v-belt to this set-up?

 

Of course!

You can put a one or two grove pulley between the hub and blower pulley.



I have a one groove pulley there, with a small spacer, so it is effectively the thickness of a two groove pulley.

These index on the hub, and the blower pulley indexes on it.

 

OK great. We don't have these luxuries with Flatheads, so I don't know much about these set-ups.
Please correct me if I'm wrong:
So the order on the crank would be hub, degree ring, v-belt pully(s) and blower pulley?
Boy, that looks like it sticks out about 8" of the face of the block! This is the kind of measurements I'd need to check if this would fit in my 35 coupe. I don't want to buy anything until I have a decent idea what I'm trying to work with. I think I would need a single v-belt as your picture shows to run the alternator. If that's your motor in the picture, would it be possible to get a rough measurement from the block to the face of the pulley? Also, is this how you figure out what the blower snout size needs to be or do you start with the snout?
Thank you Joe

 

I will measure it.

My best advice is to start at the crank. Put everything there that needs to be there.

Get your water pump/alternator/pulleys/v-belt square away

Then use a long straight edge to determine the snout length.

My single groove crank pulley is pushed forward by a spacer that puts that groove in the same position as the outer groove in a two groove pulley.

That is a BBC water pump on Hot Heads adapters, with their timing cover.

 

I had A LOT of help from other's, and they know who they are.......... Basically, this......... Blower set up=snout length, but before that= Stock h20 crossover, or BBC?, which entails the timing cover, water pump adapters, etc.......Then, what drive? 2'' or 3''? = Your space may vary.........Mock up, and A LOT of foresight is your friend in this deal.........Plan things out before you start buying......... The pulley is easy.....1/2,even 3 groove is available, depending on what you want to run.......Machinist's are your best friends........Good Vibrations has an extensive stock of new/used spacers/hubs/drives,etc...........If it was paint by numbers, everyone would do it. Sometimes you have to be real crafty with things..........Learning to swim is easy=kinda, but if you get thrown in the deep end first, well, kinda like that.......
Just do your homework. Good luck!

 

Thank you, I appreciate the help!

 

Great advise! I'll have to figure that all out and the 2" or 3" pulley is still unknown. If the 2" set up works out, I'd go that way to save space. So glad a good friend of mine has a beautiful machine shop locally and has helped me immensely in the past. Thanks for your help Joe

 

Be aware that a 2-inch drive might not actually save space.

The lower pulley mounts "cup out".



The upper pulley on this would be "cup in".



If you want to save space, that would require a shorter snout.

That would make measurements meaningless.

 

Man I have a lot to learn! I didn't know the pulleys had a in and out mount. I searched on line and basically found two snout lengths 3.90" and 5.15". Will the belt on a 3.90" snout with the pulley mounted "cup in" clear the water pump, etc.? Does the blower pulley ever get mounted "cup out"? Sorry for these basic questions.

 

I pulled the blower pulley off today to measure the snout. The snout measures 7 1/2" from the front of the pulley flange to the drive surface. There was also an 11/16" thick spacer between the flange and the pulley. The flange just fits inside the pulley.
Is that a spacer or more of a support washer that makes up the difference between the snout flange size and the size of the inside of the pulley or both?
I attached some pictures of the upper and lower pulley set-up that came with the blower.
Thank you Joe

 

Based on the components that you have shown, this blower was on a Chevy with a long water pump.

If you want a 2-inch drive setup, you will need to start at the crank,****embly the water pump and alternator, and build from there.

Any other way will likely end up in a frustrating exercise is buying, returning, and re-buying parts.

2-inch belts are still an industrial product.

2-inch pulleys are getting harder to find.

I cut down more plentiful 3-inch (3-1/2" actual) pulleys to make 2-inch ones (2-1/2" actual).

Keep in mind, there are two center hole diameters, so you will need to know your dimensions.

There are 2-inch register holes, and 2-1/4 inch register holes.

I think the 2" belt would be the way for me to go because of the limited area I'll have to work with in a 1935 Ford Coupe. Cutting down the pulley is a great idea and a path I'd have to take if one is not available. Saving an inch of space will really help. Thank you Joe
