I will be using dry graphite lube between the springs. Does this pitting matter?
No, it doesn't matter. I would still try to remove more rust with a wire wheel or another rust removal method, but it isn't really necessary. Be sure to grind the lower outer edges smooth on each leaf so they won't dig anymore into the top of the next leaf.
Mixing the dry graphite into the paint makes it last longer - and that's the method Ford used
Tom, those aren't rust pits. They are lubricant reservoirs! Just fill them up and proceed.
Allan from down under.
Allen has it right....lubricant reservoirs.... Jerry.
For springs try this. http://www.tractorsupply.com/tsc/product/ez-slide-graphite-based-coating-1-qt?cm _vc=-10005 beats trying to mix your own. Only paint the under side contact surface. None goes on the bottom leaf.
Thanks Roger, Allan and Jerry! Funny...and makes sense about the "lubricant reservoirs" :-)
John, I've seen that mentioned before about not putting on the bottom leaves. Why?
"John, I've seen that mentioned before about not putting on the bottom leaves. Why?"
You only need to paint the bottoms of the leaves where they make contact. The upper leaf slides over the lower one. The paint is not really weather resistant and if you paint the top surfaces it won't protect the spring from the elements. Also I think the sliding action would remove the paint from the leaf upper surfaces if painted.
I painted with graphite mixed greyish paint all around the leaves, let them dry and assembled the pack with some grease, cleaned off the grease on the outside with acetone and finish painted the outside with regular black paint. Looks good and works fine
Thanks John and Roger!
