I'm down to the last inch of compression ***embling this Posie A spring on the Quick Change rear. I've just can't seem to get it together. I have Vise Grip C clamps to the point of where i can't get them closed anymore, I have a couple of 8 inch heavy duty C clamps also working. The nut on the center bolt is getting very difficult to turn. I've done several of these but this ones kicking my ****. Maybe take a break over night. Maybe I'm getting old?
Do you have the ends of the main spring mounted already? And trying to force the rest of the spring pack together ? ...
Have you thought about making a set of spring clamps? 4 pieces of 1/2×1 crs bar stock wide enough to go from side to side of the spring. Drill bolt holes wide enough to clear the spring and use 4 grade 8 fine thread bolts and nuts, 1/2-20, and never seize. Put them on either side of the center bolt, and pull it together with the 4 bolts. No pictures or drawing, but I think you'll understand the idea
Main leaf is on the spring hangers on the quick change hosing ends, Reversed eye main. I had the leaves captured with a pair of homemade clamps so they couldn't slip sideways. Just not enough muscle. Got tired of screwing with it, took a short run up to the local semi repair shop and borrowed a pair of some really big C clamps. They made short work of the last inch of compression needed. Now it's resting over night, tomorrow I'll pull out the ready rod and put the spring bolt back in. This is probably the last one I'll ever do?
ready rod? Threaded rod or all thread? Course thread. That stuff isn't rated for much but we did have it at work in 4130 or grd8 $$$. Be damned if I can remember what/where it was used. Just write on the garage wall how you did it for "next" time.
I was going to say in your situation I use 4 big clamps, slowly working all 4 at the same time. And if room permits, I run 1 clamp up and the one next to it down and the same on the other side of the spring center bolt. This way I don't have to fight the handles being right beside each other ! Anyway glad you got her all figured out !! ..
I purchased from a Model A resto parts vendor a center bolt with the correct square head but with a really long thread on it. Between c-clamps and the long bolt (with oiled threads) I have never had a problem. After tighten it up you just cut the extra threads off.
Yea I was using oiled ready rod and c clamp Vise Grips until I couldn't tighten it any more. Trust me I've done quite a few of these ***embling my own and customers ch***is. This particular spring just was a little tougher than the others?
Did mine on the car. Long center bolt and clamps to pull it into the crossmember. Just kept tightening the center nut, then the clamps and it pulled together. Cut the excess off the bolt when I had done. I made a bolt by grinding the hex head to a square to fit the crossmember
