If you caught the knock before the crank was damaged beyond turning, you will be money and quality ahead to have your crank ground.

As for finding a good machine shop, go where the racers go! There are a lot of shops that somehow stay in business in spite of doing horrible work, so do some research!

When you find a shop you want to use, take the crank and rods to them, have them measure everything, see what they recommend. They can either supply the correct undersize bearings or tell you what to get. Be sure to give them the model and serial # of the engine if available.

The wrist pin is held in with circlips, the bushing is pressed into the rod. It is then precision honed to size, a very close and critical fit. Something that the machine shop will do for you, takes special equipment. Also have then check the rods, they may need to be resized, especially the one that was knocking.

Are you replacing the pistons and liners? If this is a working tractor, now is the time to do it. If you're not replacing the liners, they at least need to come out and replace the orings where they seal to the block. Also would be a good time to have the valves gone through. How is the oil pump? Remember, when the bearing failed, it probably shed some metal. That metal is now lurking in the oil galleys, so clean everything like it's life depends on it!

If you don't have a shop manual, it would be a very cost effective investment!
