Problem

Track roller groups on certain 215D, 219D, 225D, 227, 229D, 231D, and 235C Hydraulic Excavators may have incorrect surface finish on roller shafts. Operation of excavators with these rollers can result in scoring of the roller bearing that leads to loss of lubricant and subsequent roller failure. This also applies to any 8E4573, 8E4576, or 8E4579 Track Roller Group that has been installed as a parts replacement.
