Can someone school me on the roadster spring.. I believe they are all 7 leaves....my question is if there is a difference between a 1928 and a 1929,1930, 1931? thanks
 
brokenspoke,

Try this, should cover all cars....BTW, no difference.

. .. Rear spring exploded drawing....

didn't work, look in search, at the top of the page.

The roadster spring is the same for all years. It has seven leaves plus a spacer, so the chassis clamps are the same as a coupe or phaeton.
 
I was told by a old timer that in 1928 the roadster had a spring shaped like a Model T spring..then changed it to the more common roadster spring....any one have a picture of it if this is true

The different shape comes from the different number of leaves amounting to different spring pressure on the main leaf.
 
The "True" roadster spring has a different configuration than the 8 or 10 leave springs....the amout of leaves does not change that....My orginal question is if there is a difference between 1928 and the others, 29, 30, and 31 on the roadsters?
 
Marco told me NO, they are all the same. Seven leaves on the top and a dummy
on the bottom. If you are looking at the drawing in the Service Bulletins? It left
me confused also, my roadster spring " looks " like an ordinary spring ( same shape ).
If you did the search, from my first post, you can measure the springs to see if you
have the correct one. Still frustrated ?
 
I just found a ( A springs.com ) he has a true roadster spring listed...he says that they are different configuration but the same cord length, I'm still confused yes

I bought a 7 leaf roadster spring from (A springs.com) and it only had 7 leaves and did not include the dummy leaf that is necessary to make it a true roadster spring. The ends of each leaf were not beveled, so the whole spring had to be disassembled and I beveled each leaf so they would not wear on the leaves below them. The paint quality was terrible so the leaves had to be sanded,cleaned, primed and painted, greased and reassembled.....

Marco..told me 7 leafs on top and filler on the bottom Question:
What difference or problem, if any, to locate filler/dummy leaf on bottom or top of the roadster spring? Does it have to do with contour of rear cross member?

Was the spring a different configeration from standard spring?
 
..." configuration "... as in shape ? I asked you this in my second response,
are YOU looking at the picture in the Service Bulletins ?

Maybe somebody can post a photo of a Roadster rear spring...PLEASE

If you put the dummy leaf on top it will jack up the rear of the car by that thickness.
 
Al original A spring leaves were tapered on the ends; replacement springs leaves, front or rear, will usually be square cut on the ends.

I believe a original Roadster main leaf rear spring had a different shape than the main leaf spring in a 8 leaf rear spring.

As said above, the roadster 7 leaf rear spring had a dummy spring on the bottom; the u-bolts and spacer bars were the same as used on 8 leaf springs installed in Coupes and Phaetons.

Some where among my litature I have an article that Ford issued (sorry can't seem to locate) . The just of the article was : the Roadster rear spring will no longer be produced, the article went on to say to use a 8 leaf rear spring, it told which leaf to remove, and to make a dummy leaf for the bottom. I recall the leaf to be removed was above the spring clamps so the clamps wouldn't have to be changed.

I made the above modification on my 28 Roadster back in 1968 as I couldn't locate an original 7 leaf spring. I put lots of miles on the Roadster and never had a problem nor did this spring change the appearance of the Roadster regarding side view.

I do not know, I had no original to compare it with....
 
If I'm interepreting the parts price list correctly, the main leaf was the same on all years, 28-31, and was used on several body styles including the 40A & B. I bought a new spring from Snyders for my roadster. I took it apart, sand blasted it, sprayed the mating surface with slip spray, reassembled and painted. It works.
