I want to use the complete F1 backing plates, spindles, king pins, brakes & drums on a Mod A dropped axle. Can it be done? yes, I've read all the threads i could find, so far I've come away with this: Yes, it can be done. No, it can't. Who has done it? can you tell me (all of us) how you did it? any details, part #s etc & pics will be helpful. thank you, mike roman (the junkyard pirate)
Everything is bolt on but you need to change the wheel bearings. There's a rod custom article I think on the whole swap. I had it but lost it with this new computer. I will look for my hard copy and send you the timken numbers later.
Speedway has a kit to put F1 brakes on 37-48 spindles. I don't know if those spindles fit an A axle, but you can buy those spindles pretty cheap.
if I am using EveryThing from the F1 axle but the axle itself, I shouldn't need to change out the bearings should I? interested in seeing the article, thanks
i already have the Mod A axle & the F1 axle with all new brakes, wheel cylinder etc. just trying to use what I have.
Don't think the F1 spindles will work, different size kingpin. The backing plates and drums will work with a little work, you have to grind the edge of the spindle to clear the backing plate and change the bearings. Did it years ago but don't remember the bearing numbers.
I used the F1 king pins to install the complete f1 spindles and brakes on a dropped super bell model A axle. The steering arms needed a little heat and bending.
I used 46 48 spindles on my A axle. You need to install the 46 48 king pins to make it work. The article I referenced is for using the round back spindles and for those you definately need to change the inner bearing. The timken number is 14116. you will also need a Victor49195 seal or a National 450461 seal. Sorry it took me so long to dig this out but here it is.
You can use the f-1 spindles it’s pretty much a direct bolt up you will have to heat and bend the steering arms accordingly
