59A flathead with offset gen ..show me your fan mount setup!

Ive got Dans AV8 in the shop for an engine swap..going from an 8BA to a 59A motor, so all the fan and generator are wrong offset for the pulleys. The offset Generator is easy (swap for an early one with the mount on the front housing) but the Fan is a bit harder, being in an A there isnt much room, and the fan needs to swing from a point Below the generator mount stud,or maybe straight out of the stud.. has anyone got photos of how they did this and an idea of what combo of bits you used to achieve it? .heres a shot of what Im working with. the 8BA fan is of course totally wrong and I dont really think I can use it even chopped up and changed around, its just too long and big.







It will be running a triple Harrell intake, the stock intake is there for mockup only.

 

Just ran a search and looked through all the relevant threads..seems Im on my own here.. no-one seems to have come up with a one belt answer to this problem..the closest thing i have found is there is a bracket that Offy makes to eliminate the two piece setup and bolt the fan directly to the manifold mount stud, but that aint gonna help me as it sets the fan up high where it will contact the upper hoses..

 

I'm hoping someone chimes in, we're putting a 59ab in kwmpa's '34 pickup and running into the same problem! Even if you made a bracket to mount the fan inline with the other pulleys, the high offset generator position prevents the belt from contacting the fan pulley.

 

Damn you beat me too it...i need to figure this out...i was looking at it tonight..still kinda puzzled

 

yep its going to take a few hours headscratching I think. I remember seeing Aussiesteve had a fan that stuck straight out of the generator boss, I think he actually milled the intake to take bearings, and machined a shaft to go into it. its hard to do this kind of job for a customer at hourly rates..you can quickly end up with a 1500 dollar fan!!

 

trust me dude i feel your pain...we go through that **** all the time where i work

 

Yeah, it could easily take a LOT of work to do. I think we actually have enough room to use the double pulley. We're going to make a bracket that mounts to the front 4 intake bolts to hold the fan carrier. The Evans 3x2 intake he's running has no gen mount so we HAVE to use the offset head mount.

 

One solution is to remove fan from asembly like I did since fan interfered with upper hoses. With no hood it doesn't need a fan unless idling for long periods in hot weather.

 

In flipping through my Bishop&Tardel book. He says he uses a bracket that Specialty Ford Parts sells and uses a v8-60 pulley fitted to a later hub with a shortened 37 fan. Theres some OK... pics of it in the book.

 

I have seen some old setups where guys would actually cut down an old generator of the type that the fan mounts directly to. It will mount with all three carbs on the manifold and act as a tensioner as well.

 

Thats pretty much what the one in the book looks like to me.

 

did you ever figure this out?

 

The picture is pretty weak. But, I did use a cut-down generator with an offset generator mount on my A roadster. It is pretty tight between the upper hoses and the distributor. But, it is functional and I built it on my own with no machine work. The fan does act as sort of a "tensioner" and if you need more clearance, you can cut down the fan blades.

 

Thanks steve.

yes we did use a three carb Harrell intake, so offset gen a necessity.
I ended up dismantling a 35 or 36 gen, and the front bearings were opposed taper rollers, so I could chop the front of the shaft off, and use it for a fan mount, and it is self supporting ! I welded a square bracket to set this into, and that bolts on using the standard 9/16 stud sticking out the front of the manifold. very simple, but would have been very tricky if I didnt find the double taper bearing setup already nutted out by mr Ford!

sorry the car is all finished and gone, and I didnt take finished photos.

 

Maybe like this?

 

Here's a pic of mine I used a 37 fan cut down (as I'm running a magneto and space was very tight) an 8ba fan carrier that i cut the back where the shaft p***es through and then pressed the shaft all the way through as much as i could get it then welded the fan mount hub to the belt sheave shifted the generator to the side and run one belt all the round works fine.

 

hey grenade inspector could we get a close up on your fan mount. nice ride

 

Here is the setup on my coupe:

 

hey what did you use for a mount at the manifold?

 

Here are a few pics of my cut-down generator fan mount. I know that it's a flathead era generator. But, I'm not sure of the exact year as it came from a parts pile. When I cut the generator in half, I lost the rear bushing that goes into the back housing of the generator. I took it down to my local machine shop and he fitted a bronze bushing (see pic.) to the back of the shaft for support. I just got it back today and it feels much more solid. I still may need to trim the blades a little to get the radiator down lower to make a hood work.

Thanks,
Mitch

 

Looking at your set up. I’m wondering where you got the mount bracket + shaft & pulley. Needing just that to help with belt load off side generator. I’m running electric fan. Thanks

 

What about using a 32 v8 fan? Mounted to generator.
This is on a 21 stud but I’ve run the same setup on 24 stud motors.
