Thanks guys. I wondered about a 'wear plate' concept also. I have some self adhesive UHMW strips I had my eye on, but I thought it wouldnt stay in place so came up with the tin wrapping concept.
Besides giving it a smoother surface to rub against, it takes out some of the slop side to side, which should help. And if wanted to get fancy, could cut a small arc section out of a piece of pipe to weld it in - which would give a much larger surface for it to slide against and help slow the wear rate.
Was thinking that spring might be short. And wondering if someone had welded on it prior, could have pretty easily detempered the spring (if they didnt remove it for welding). Otherwise its just been crunched so much it has taken a set.
Time for some new parts - but Im still going to have to figure out how to do it without a welder (buying an old tractor is one thing, then going out and buying a welder to fix the old tractor, while would be suitable to me, might get some raised eyebrows from the misses....)
