Took oxy/acetylene to get the master pin loose and 18 pounds to beat it out. Whew!
One bolt drilled and hole cleaned up, two to go.
I am so glad I got it out of the mud hole it broke down in!

Got all the sheared off bolts drilled out and the holes cleaned up perfectly with a tap. Reassembled the yoke and idler today. Need a new master pin and bushing then it's off to the races before the snow starts or the ground freezes up. It's been a couple nice days in the woods here. Lotsa turkey, deer and bear. The mushrooms are popping up like mad too.

Better check the wear on the idler bearing blocks and frame wear strips or it may happen again if the yoke is being placed in a bind.
I was able to tighten up the wear blocks by removing the shims. The idler axle is tight in the bearings which are also good. Hoping this doesn't happen again. Replaced the bolts on the other side as a preventive measure.

Jon---what do you think caused this? did you hit something with front of the track, or maybe turning and hit something? also the track had a master pin and not a z bolted track link?
Those shims are just for aligning the idler, they don't do anything for vertical movement due to wear.
