Use a dial indicator. Push the attachment against the ground to lift the excavator off the ground and take measurements at 4 points, 90 apart, around the circumference of the bearing. Record and keep all measurements. Play in the bearing should increase minimally from one inspection to the next. Eventually, however, as the bearing begins to approach the limit of its service life, clearance increases become much more pronounced and the actual measured play in the bearing could exceed twice the value that was measured when the machine was new.
