steering box ratios

[77fixer]

Found out why I couldn't get my box back together. I had mixed up the rack pistons between two boxes.
Now does anyone know how to determine ratios from the number of turns on the worm. One has 6 full turns and one has 8. Seems the one with 6 would be faster, but which would work better with a 1.5" ram.

Hmm. I started studying after reading your post. /forums/images/graemlins/smile.gif

Didn't find anything real valuable, but some interesting info (to me) here: look under "upgrading"

How many turns is the box you are working on lock to lock? Kind of curious to know if these are variable or constant ratio.

I never thought to check lock to lock on these, assuming they were the same. One is from an 78 C25 (the one with 6 turns) and the other is out of a 74 K5.
As far as the ratio, I think these are both constant since the the twist looks like it is equal from end to end.
This has definitely been a learning experience. I am glad that I have done it.
Just another thought, and I don't know if there is any relation at all, but it makes me wonder since they list a 12.7 and 16:1 and these worms have a full 6 turns and almost 8. Could mean absolutely nothing.
