Justin I have rebuilt a few WC / WD shifters. Here was my simplistic approach. Most of the wear at the ball is obvious, particularily near the groove. I arc welded up as best as possible - putting enough bead to cover the worn groove. I rough ground the ball and slotted the groove with a right angle grinder. Then finished up with a large mill file to round the ball and straighten the groove. Fit the groove with the pin head - I have used a tight fit. Put a little weld on the tip too & file to size. There have been numbers published, but I eyeballed it. Then take the shift tower off, and remove the forks. Weld and grind some more to get square slots. If you do one fork, you will have to do all 3. It makes it makes it easier to find each gear. Reassemble with new pins from AGCO. A little more filling to make it work smoothly. Takes some time and handwork, but they shift well when done. I have not relined the tower pin holes. Doing the above tightens it up well enough. kevin
