Helper Spring Project
 
1 Attachment(s)
I have been thinking about building my own helper spring for my narrow frame Cubs. I thinking about basing it on the Brinly spring, which uses the 3 point lift arm as an anchor for the lift and the frame as the stationary point and adjustment. The problem will be in sizing the spring and finding the right anchor point on the lift arm. Here's my idea.

Just a little problem... How are you going to adjust that?

The same way you do with the Brinly and the IH assist springs. You can turn in or out the nut on the eye bolt therefore either increasing or decreasing the length of the spring which in turn adjusts the tension on the spring. The thing I can see where the problem may lie is in that the spring may want to torque, but I think that won't happen. If it does, I can put a jam nut in the system.

The spring won't torque very much, if at all, as long as the threads are good on the eyebolt and nut.

I agree, that's what I was thinking also that there wouldn't be much torquing, if any.

I also have another idea that's kicking around in my head - I just need to model it also to see what it would look like and to see if it's feasible.

springs
 
I've put on a few IH spring assists and they do torque over a bit. It's a spring it's gonna give a little.

I'm sorry I really didn't define my question, I can see HOW you would adjust it, but being on a NF and haveing the rear lift there, will you even be able to reach it?

NF helper spring
 
If the spring does torque too much, get a longer threaded eyebolt and put a double nut (jambed) on the end to hold it with. That is providing you have enough room. Hold the jambed nuts with one wrench and tighten/loosen the adjusting nut. Just my :TwoCents:

FFGino. Happy Cubbing!

I have a 123 with a 3 point lift and a Brinly assist spring and yes, you can reach it. Here's my 104 when the Brinly assist was on it - it also has the 3 point lift.

Alrighty then! Just the way it looked in your first post just made me think it might be outa reach
