Looks like I'm opting for doing the shop work...all I could find is that somebody wants about $1300 for a used mast. (Surely new, at Koyker, wouldn't be less.)
My general comment about the 640 loaders: I've never had any other loader that has had as many structural problems/weaknesses as this one. I'm the 2nd owner, so maybe the 1st guy abused it? Anyway it has developed cracks & had to be fixed in too many places. (You can see one of my repairs as a weld around the top SL arm pin in one of the pic's.)
Having this mast break out at the bottom is just one more example of a tool that was build too light for the up-to-85-hp. MFWD tractors it was designed for.
I think a *universal problem* with these loaders is that the rod which connects the R & L sides of the "tabs" that pick up/rock the bucket gets loose so that the tabs aren't aligned when you go to pick up a bucket or other tool, requiring more fooling around than it ought to.
Oh well, off to the shop to weld, beat, and hack my way to a repair!
