The rod should have less than .001" up and down play.
The big end of the rod shouldn't have more than .028" side to side play.
The small end bearing and wrist pin should not be able to "twist", only rotate smoothly. The small end of the rod shouldn't be able to be pushed side to side more than .039" The overall width of the crank webs shouldn't be more than 2.281"
All of the specs I just quoted are available in the service manual downloadable out of the "general support" section of this forum.
