Leafspring bolts
« on: February 03, 2014, 01:41:13 PM »
Hello folks.

Paavo have problem. My leafspring bolts and brass bushes are in bad shape.
Friendly german guy Mr. Hempel offers me his good condition bolts but they are wrong type. (picture)
Werner Karasch & Co. GmbH offers me same type because those belongs 1937 model.
Bolts in my car are older version. Is this correct?

Asking confused Paavo :-\

I think you can substitute the threaded bolts as long as the length is correct. If I remember correctly, they are the same length top and bottom on the 170 V, different lengths for the 170 Va with the tube shocks.

My friend can made new bolts with lathe but hardening is the problem.
New bolts is 130 piece. Total 520   :o
Two of the bolts is longer. Its fore lever shocks. See picture.
In older pictures lever shock is attaced to upper leafspring but in my car the shocks is in lower spring. (prior owner modification/mistake??) What is the correct way or is it the same?
None has extra good/restorable bolts in carage shelf to sell?
brass parts is easy made

Regards poor Paavo ;)

We still have the roadster at the shop. Let me look at it to refresh my memory. What is wrong with Mr. Hempel's bolts, the length? I think I have some extra bolts too.

Hello Henry

Mr Hempels bolts are perfect, but unfortunately wrong type.
Compare pictures. Leaf springs and bolts are different.

If your extra bolts is "my type" I am very interest.

OK, one thing I assumed but may be incorrect is that the threads on the outside of the bushing are not really threads, but just there for the spring to grip the bushing, ie the spring leaf itself is not threaded. Both my 38 and the 39 roadster had threaded bushings and pins. I'm assuming these were retrofitted into original springs, but maybe not. Since it seems that a lot of these cars were rebuilt after the war, some at the factory, it's hard to know what is what.

I looked at our car. The link for the lever shock absorber is on the top bolt. Since the bracket for this is about the same thickness as the stop plate for the steering travel, which goes on the bottom, the top and bottom bolt lengths are the same.

I suspect that these bolts are the same as the Va lower bolts, since that's where the tube shock mounts and as far as I remember, there is nothing extra mounting on the Va top bolt so it is shorter, too short for either the shock link or the stop plate.
