Magneto and belts

[3W Hank]

I think I might made a misstake with my set-up on wateter pump belt and a magneto.

Block is 59BA.
Generator is a 37 on a PM intake.
Crank pulley, dont know but I think seller said it was a dual now cutted and will work to generator.
Waterpums its just mock-up and pulley is rather tight but I’m not shore if its 59BA or 8AB.
Cam cover is 8AB so magnet is a early Scintilla but lower part is for the 8AB.

I had the idea to get a 3-bolt cam cover and angle adapter but I realise it would be very hard on both short and the longer adapter and a fan ( ex 32 ) no matter of angle on magneto ( did not like electrical fan )
I did try to seek on Hamb ’wanted’ on both angle adapter and a magnto but not much calls ( junk ) or Very expensiveeven tuff shape.

So one day I came over the magneto for a resonable price and a nice tag but it was foot for a 8AB.
But magneto was burned so Cirello in LA has now fixed it, so with a NOS cap, NOS pointers, cam cover and all car time ( cost ) and freights, repairs its now a expensive unit. I guess way over 2K in it.

But I mock it upp fast here and where belt is there the magneto body.
It must be impossible with this set-up of pulley ( or ) ?
I thought this was the ’easy’ way, not as cool as a angle drive.
Hard to get pictures but here is the set-up.
Ideas how to solve this.

a front view would help

You need to use 8BA style water pumps and crank pulley when your using that type of front cover. Use Ford flathead truck F-1 water pumps their mounts will match the early water pumps you have in the photo.

The problem is you can't run a late distributor/magneto off the timing cover and still run the early 37-48 water pumps and crank pulley. When they moved the distributor to the side in 49 - 53 they also changed the crank pulley and the water pumps (along with the timing cover cam/crank gears, etc). The later water pumps put the belts further away from the block - such that there is room for the belt to go by the distributor. You could make the front of the motor "act like a 49-53 - with the later crank pulley, water pumps, etc.. That is what Ronnie is talking about . . . but that brings in another whole set of issues (depending on the frame/year you're putting this into).

Also, you have to think about your generator and fan - your setup will not work with the belts being moved further forward (using the late F1 water pumps) - so there is another problem.

So, if you're putting all of this in a stock 32 frame, you just created a big problem --> the crankshaft pulley now wants to be in the middle of the front cross-member. Some folks "jacked their engines up" - but that looks like crap. So, if you're putting this in a 32-34 frame and want the engine in the stock location . . . you're kind of hosed. You really need to go back to a front-mount ignition (angle drive magneto, crab distributor, etc). There is no room for the later crankshaft pulley - with the engine in the correct location. Hell, there is barely room for a single-sheeve crankshaft pulley in the stock location!

Also, you probably don't want to move the engine back - then you have firewall and a host of other issues (think transmission location, clutch location, etc, etc, etc.).

Ok.
A question.
I has invested to much effort in the 8AB set-up so I cant build the case on try use a 38 generator and a std 32 fan.
But…if I found a doubble crank pulley and use the RT pumps can I use the inner to generstor and outer to pumps.
Would that work.

Or try to use a smaller pulley to bend the belt around the lower part of magnet (?)

Like this, a extra tension wheel move away the belt from mag.

I still don't think that is going to clear, but the only true way to know is to mock it up. Use a rope to simulate the belt

Like this? Works...keeps the belt below the base of the Chevy distributor. The belt tends to crack after about 6-7000 miles with the reverse bend around the pulley.

Coming up with a solution to re-route the belt could still allow you to run the rest of the necessary early water pumps, early crank pulley, etc.. If you're willing to make parts and customize how the belts work, then you should be able to solve the problem.

Having big-bends in these ole' v-belts will shorten their useful life, but who cares (just keep a spare in your truck). Given all the belt bends - that is why the automotive world went to serpentine belts many years ago.

Also, you should be able to run the 32 fan in the stock location (on the generator) - which makes the whole setup a LOT easier to do (in a 32 - 34 chassis). You'll also be able to use the stock 32 motor mounts - which is a big plus if you have a stock front cross-member. (with just a bit of clearancing for the later 37 -48 belt angles).

Yeah, something like that should work. The fan setup scares the heck out of me - especially from the perspective of balance and wobble. I sure wouldn't be running it at the RPM that I tend to do in my 32! LOL

[3W Hank]

Well I like the idea rew 6K..but a fan blade made 1932 and some rust tension in the rivets, jepp not the best idea in the world !

I will never in reality do a burnout with this car ir rew 6K.
But I lathed a mock up tension pulley at OD 2.5” and it look like this.
It will clear.
But how belt tension will be here I has not yet figure out.

Note, the magnet will go down more, as Ciirello made a new longer axle so I can has the steady rest in the cover.
( I need ream up hole some )

The fan setup is stock 1941 Mercury crank driven. Henry probably didn't approve of hot rodders like you! LOL

I know the crank pulley is stock . . . is that long extended fan also stock? I've never built a flathead/car of that year.

The belt tension is set by raising/lowering the generator (where the fan will also mount).

Yes, it is. Seems crazy doesn't it?

[3W Hank]

Its not that uncommon to use a stock 32 fan on a older generator in a 32 chassie as I understand it.
I heard of 32 wings has fly out cars on hwy…
But my is in a very nice condition, not pitted.

I was just try to give this issue a sololution.
Shore I can bought RT pumps but that get me change the idea on the generator/fan.
It also look better with belt closer to block ( my opinion )
I got a pretty straight line.

But it might be needed move out the water pump pulley atleast some, so my bet it will be RT pumps.

Anyone know this company is still fix pumps ?
I need get the pulley out some to clear the covers.
