ford model A spindles and 40 ford brakes

ok, i looked this up on the "search" but didnt find what iw as looking for.

ok i was wondering if the 40 ford hubs are going to fit on the model A spindles? or will i need to use the model A hubs with the 40 ford drums??? i still havent yet tried to bolt anything up. and havent even tried to bolt up my backing plates(still have the model A ones on)

can someone give me the low down on how everything will work. ive never done this conversion to juice before.

do i need to go buy diff bearings maybe???

 

check speedway motors or PM JIM A he did it to his Mod-A

 

You can get a kit that has a ring to bolt the later backing plates (37 to 48) to the early spindle (28 to 36) and a spacer that slides on the spindle and allows the later drum....

I think the kit is like $20, Spedway has them...

 

interesting, (and even better, CHEAP)

what'll they think of next!

 

2 words. HELL! YES! thanks guys do i use the stock hubs??

You use the A spindles,
mount the spacer(who btw is same dimensions as a model A piston ring,I've been told ) into the 40 backing plate,clamp it on to the backingplate mounting flange on the spindel,
and either widen the existing holes or drill new ones.
the mounting-holes in the 40 B-pl are a little different from the ones in the A spindle.
If you turn/tilt the backing plate some degrees, before drilling,you will have fresh new material to drill in.

And cut off the mech-brake stuff on the A perchbolts,or get new ones,so your brakehoses have plenty of space.
Add small spacer,new seal,and tighten up.
Ready to go.


Did this make any sense?

 

OK, so i went outside and dove into the front end.(at 3am..." i swear officer it wasnt me making the noise") got the mechanical brakes off and the steering arms ect.

i held the 40 ford backing plates up to the model A spindle, and i see what you mean about the holes being wider. i understand the backing plate part now. what i dont understand is, what hubs do i use? will the stock model A hubs fit on the 40 ford drums?? or do i need the 40 ford hubs??

after i get this info im well on my way to getting my front end together! now all i gotta do is press out the spring perches(after i make a press) and split the wishbones(ones cracked so i gotta replace one side*i got 2 front ends to make one, each has 1 cracked wishbone*)THANKS!

 

You use the 40 hubs,drums and backingplate on the A spindle.
(Thats why you have the little spacer,there are a little difference in the bearing area on a 40 and a A... )

I have done this with a widwfive 39 or something-to A ,but I think its the same.

 

sweet! so the 40 ford stock front bearings will fit fine?? as long as i get that kit, anyone know if that kit comes with both sides or just one???

 

I heard that about the piston ring also fitting, but I think the correct spacer is thicker.

Yeah, you've got to use the '40 hubs. '40 drums are deeper so the hubs are that much different.

 

And bearings are all the same, only difference is that they live about 1/2" farther apart in A hubs, so the little spacer is to take up the space. Just select the 4 best ones you have after washing... Plate spacer does look like a piston ring, but a good deal smaller bore than an A!
The holes just need to be filed oval in an inward direction for a fraction of an inch--old timers usually just slotted them right over to the big center hole, to judge from my collection of plates!

 

So we can finally bust the myth about the piston ring fitting in there?
I have the measurements for the plate spacer right here.
If you have a equipment to make it yourself.
In good ol'e metric measures that is.


Plate spacer - 3mm thick. (could be better with 4,and grinded flush with backing plate,if you choose to weld it) id-92 mm od-100 mm.

I did weld the plate-spacer on to the backing plate,filled the old holes,turned it a few degrees and drilled new holes.

(Note-- these measures are for the backing plate I had. check yours before you make it)

 

" So we can finally bust the myth about the piston ring fitting in there? " Nope ... The piston-rings fits just fine , problem is , I have no idea if they came from a Model "T" or an "A" .. I belive I have read somewhere that they where from Model "A" , But it might be Model "T" rings ??
The only reason I know this is that the first "Juice-brakes to `32 Ford"- Kit I bought came with 2 small spacers & 2 Piston-rings !!!

 

I wouldn't weld on a brittle piston ring. I was thinking of cutting up the A backing plates ang grafting the center section bolt holes and all to the 40 backing plate.

 

Use the round back spindles ('37 style) on the Model A axle, they fit right on, and install bolt on steering arms. I also use needle bearing king pins to make a big difference in steering effort. With those mods the '40 hubs and drums and backing plates fit just like they were made for it. Be sure you bone up on proper brake adjustment process, a fiddly process, or use '46-'48 backing plates with self centering anchor pins. A great setup with no drilling, welding or other hacks involved.

 

I bought one of these kits from JC Whitney 65 years ago and it worked fine on a 33 sedan

 

That, and the fact that the OP is banned.
