I just picked up some NOS shackles. The kind with the grease fittings and metal sleeves. My question is...do the two sides (the flat and the side with the grease fittings) just rub up against the spring eye? This seems wrong but it's what looks to be correct in assembly and in illustrations. Won't this be a bind point? Won't it just be metal on metal? Thanks!
I haven't had much coffee yet and I'm at work with no hardware...but Ford shackles were made approximately so: Center was a stud with square shoulders to lock shackle bar solidly to stud when screwed together and a big center area swiveling within the outer sleeve. Betwixt sleeve and stud is a layer of I think waxed fabric or some such 1930's moral equivalent of teflon polyurethane whatsit. Sleeve serves as outer shell of pivot, stud can pivot under spring deflection but can't move axially, so shackle bars don't rub on the parts if properly inserted. Device gots to be inserted by force applied to outer shell only--force applied to stud will breakitloose and bollix the works. Special drivers and pullers exist and would also be fairly easy to make or improvise.
I have a set of the square shouldered ones too but I am working with these. I like the sculptured look of these better but there is no room for anything between the ends of the shackles and the spring eye wher the modern style ones have the shoulder from the plastic insert.
Those are A I think. I also think what you see there is what you get with stock A...grease is supposed to takecareofitall. If you do get noise from there, or if you're worried, I'd say cut don the sleeves a bit and put washers at ends, maybe the AN small OD type. A little work with a file will make a couple of ramps so grease coming out the ends fans out into the washers. Likely you won't have any trouble, though. I'd give the ends of the tubes a hard buzz against the wire wheel brush to polish, and just maybe a file notch part way into each end to direct grease to shoulder. A stuff doesn't squeak stock. V8's got the inserted sleeves.
Those are stock A. They install just as you describe, with some grease and a well placed spreader. I have them on my '30 tudor.
oh yeah, it's metal on metal alright, and if they go long enough it will rub through the bushing, and start to eat away at the shackle hangers themselves, like the previous owner let happen to mine. Installed all new ones, greased, and went. No squeaks, seem to have no wear with the grease in them
