Hi,

I have seen some Cords with only one bottom leaf. I don't know if they came this way since Cord had at least two suppliers for almost every part or if they were modified sometime over their life. I would feel more comfortable with two bottom leafs, just in case. I have a spring with 13 leafs and one bottom leaf and one with 14 leaves and two bottom leafs...take your choice.

I've never heard of a Cord front spring with only 7 leaves. Unless that's all that you can count and the others are up in the frame channel.

I did the same modification with the plate at the top of the spring, but I had to remove the top two leafs to get the same overall height on the spring, I may have used a heavier plate, I don't remember.

It sounds like the car is coming along, do you think it will be on the road this year?

Jim

This is the front spring I removed from my 812. I counted 14 leafs on this bundle, I am sure it has never been out of the chassis since birth.

balinwire replied the topic: total thickness
The stack thickness is three and a quarter inch depth. The leafs are 1/4" at bottom reducing to 1/8" at the top. I have seen the 2 top curved leafs replaced with one 9" long 1/4" thick flat one to possibly keep the spring from rolling in the frame channel.

Let's pause a minute here. To my knowledge:

1. All Cords used the same front spring, and there were no [i:2c2cfuhz]factory[/i:2c2cfuhz] variations in numbers of leaves, leaf thickness, etc.
2. All of the leaves were the same thickness.
3. All springs had two identical bottom leaves, with a hole at each end.
4. All springs had 14 leaves.
5. All leaves except for three --- the two bottom ones and one in the middle to which the clamps were attached --- were rolled and tapered. That is, the leave got thinner and narrower at the ends.
6. The top "leaf" was actually a short piece of flat stock with an arc ground in the bottom to match the curved leaf under it. This "leaf" is best replaced with a longer flat piece to spread the pounding of suspension shocks over a wider area of the crossmember and reduce the tendency to crack.

This being Cords we are talking about, your newly-purchased car may have any number of leaves, in any combination. Collectively, we've seen them all. I THINK the above info is accurate. Stan? Hank?
