Cool

For you fabricators…

I finished my spring plates for my Dana 60HP this weekend and they came out pretty well. I used my original 19 year-old sway bar mounts and some 40 year-old ½” hot roll plate from the mountain that use to be a state-of –the-art telescope in its day. Then I welded some ¼” crs spacers underneath to compensate for the 3” wide spring perches to 2 ½” springs. The final product is a tightly fitting spring plate without any slop as are the original plates used on our rigs. There are no oversize holes for the u-bolts and no gaps between the springs and the u-bolts. The location of the sway bar mount is within ½” of the original location. They are untested but appear to have no interference with high steer components and the sway bar can be disconnected with standard disconnects or custom ones. I did check the strength of the sway bar mount and found no bending with 1200psi of force applied so I don’t think a 525lb axle will deform them. They are intended to be used on road only.

sweet! That seems like a simple yet strong solution to those needing the swaybar for street use.

Nice. Are those custom leaf packs? I dont think I have seen 8 leaf spring packs up front before.

Verry nice work. I like how you did that, real slick. How did you end up mounting the u bolts on the drivers side, it looks to be some kind of spacer under the ubolt to let it go around the rib cast into the housing. I would like to see how you did that too.

The front springs are stock J20 with a long add a leaf under the spring. You can see in the pic how they protect the eye of the spring, I sort of like that. That’s the current configuration. I’ve had them in and out and had the spring packs down to four leafs to get a really flat spring so I can have some info later on for custom springs.

I made a u-bolt sleeve to prevent notching completely through the rib. The sleeve mates with a square notch ground in the rib part way. That way the sleeve is trapped and can’t rotate or slide. The sleeve is welded in place and the u-bolt is trapped in a groove.

That’s a pic of the final design. I machined the outer diameter and groove on a lathe and then cnc machined the center to match the contour of the diff casting. Unfortunately the contour of the diff casting is neither a true circle or concentric with the axis of the tubes so it can’t be finished on the lathe. It is a arc-spline that roughly forms a tear drop shape with an axis above the axis of the tubes. I roughed a 2.50” diameter hole in the center of the part with the lathe before final machining on the cnc. Each lathe part makes two sleeves.

You could make this sleeve with a piece of round stock and a hand grinder. I made a prototype on the lathe and then used a hand grinder to match the contour of the casting and beveling the edges as needed for the radius in the casting. Once I had the prototype fitted I modeled the final design and then used a cnc milling machine. The two holes in the sleeve are tooling holes for fixturing.

You should sell those u bolt cradles. I'd be interested. I'm gearing up for a Dana 60 conversion. If interested shoot me a price.

That's one of the cleanest u-bolt setups I have seen. Cheers to you. And yah, you should manufacture those things!

Well, I don’t have much time to make parts these days. I have just a couple weeks here and there before I have to go work on the mountain again and then I don’t have a home life. I’m glad to help out if I can, though.

All my designs are available in pdf free of charge and should only be used for educational purposes.

Here’s a pic of my offset shims for the rear axle.
