Worn crank?

Can anyone tell me how to spot a worn crank,Ive stripped my engine to replace oil seals and on inspection of the crank ive noticed side to side movement of the conrod between the crank webs,as this is my first re-build im not sure if thats correct,dont want to refit a duff crank but don`t want to buy a new one for no reason. Thanks :stuck_out_tongue:

Dont worry about side movement, its the up and down movement you need to be concerned with. If there is any up and down play replace the crank.
