I honestly dont know what they were thinking mid 60's to 70's on the ID decals, They finally started metal stamped tags again mid 70's
I have seen some guys have new pins machined down and bronze bushings pressed into the axle on ones that were really worn.
I suppose they're better than nothing, but only slightly. I guess it doesn't matter at all now since I sanded it off today!
The axle itself is still quite round, the largest deviation I could find was 0.005, with the average more around 0.003 so I don't think there's any need for a bushing in here, but I'm betting there will be when I get to the spindles.
I have replaced two pins with what is referred to at my place of work as drill-rod. Tightened things up nicely. Several years ago I had a very worn axle bored on the pivot and for the spindles and pressed in bronze bushings. Don't own that one anymore but it's still going just fine.
I don't have any drill-rod here that size in my stash. I think I'm not going to bother fixing the axle at this time, maybe in some other decade when it's bad enough to make fixing worthwhile.
As for the cross shaft, I don't think JB Weld is going to cut it, or rather, I suspect JB Weld rubbing against the bronze bushing will get worn down very quickly. I may revisit that with some other shafts, but I think it's not viable with the cross shaft. I think I'm going to try welding it up and machining it back down, if I screw it up I can always machine a new one or go fetch the 650 parts machine sooner than planned.
I did work on the tractor today at least, I drove out the bronze bushings in the mounting plate assembly and from the clutch pedal. The left bushing looked pretty good, especially compared to the right, and the one in the pedal was worn quite oblong.
A few more days of this and I should be able to start reassembling it.
I forgot to mention I also filled in a wear/gouge in the mounting plate assembly caused by the clutch rod hitting it. Filled in with mig wire and ground it down, then filed it smooth. The pictures unfortunately didn't turn out.
