Need a large coil spring

Thanks guys.

Called our go-to guy for heavy truck springs and he hasn't got anything that large of a diameter.I measured our D69U and the coils are 1.5" so the ID winds up too small to fit over the cylinder. I was hoping there would be enough difference in designs over the years that there would be a common spring I could use. I don't really think it has to be exactly anything, just has to fit over the cylinder and be approximately the correct length. I could even shim that or modify something if necessary.

Glum, You must be in a "nest" of these things! We got ours at a farm sale probably 40 years ago and have never seen another around here.

I wouldn't be worried about it, but my uncle wants to get one on there. I guess I'm in the tractor cab mostly so I don't hear it slamming shut every time. Got it out the other day to help the dozers push out a small storm water impoundment dam and that is the most dirt it's hauled in many years.

Hey Farmboy, I need at least 5.75" ID on the spring since it has to slip over a 5.5" OD hydraulic cylinder. Did you mean 6" OD or ID?

Here's our scraper and a picture of the current project. About 6500 yards dam which will have a standpipe installed to drain all but the last 18" of water😞 Most of the dirt was pushed by the dozers, but did some of the longer distances with the scraper and tractor. Would love to have a tracked tractor to put on it just for fun, but the only thing I have with hydraulics is a D2-5J with the engine (and steering clutches probably) stuck.

Tractors are JD 4955, high horsepower D7E and mid 50's D6-9U.

Go to NAPA. Ask the guy to see the Moog spring catalog. You can look at it by the spring type. You will probably need square ends as opposed to pigtail ends or tapered ends. They are listed by wire diameter, as well as length, and load. That is how I found the $200 Scotchman ironworker spring for $48 delivered for a pair on Ebay. But, you will need that Moog number in order to shop around. If you have a Betts spring place close by, you could also call them and ask.
