New undercarriage parts and rubber tracks are sold individually but we suggest replacing all of your worn parts at the same time.
This is the aftermarket replacement top carrier roller designed for your Volvo ECR 88 mini excavator.
This is the upper guide type roller specifically designed for the rubber track undercarriage, but will also work on our steel track undercarriage. This is the smallest roller on the undercarriage that is located in the middle of the track at the top of the undercarriage.
Use the blue arrow in the image as a reference for where this roller is installed.
