Abstract
A method of servicing a track chain assembly includes loosening a fastener to reduce a clamping force of a track link body on a track bushing. With the clamping force reduced, the method includes rotating the track bushing from a first position wherein a worn side of the track bushing faces a drive sprocket to a second position wherein an unworn side of the track bushing faces the drive sprocket. Once the track bushing in the second position, the method includes tightening the fastener to increase the clamping force on the track bushing. The method can be performed while leaving the track chain in place on a track machine.
