When an excavator undercarriage starts showing excessive wear, one common question is whether the drive sprocket or track chain should be replaced first. In many cases, the two components wear together because the sprocket teeth engage directly with the track chain bushings. Replacing only one worn component may shorten the service life of the new part if the other component is already beyond its ...
