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 replacement aftermarket sprocket idler for the JCB 8025 and 8035 mini excavators. This idler sprocket requires a bearing which is not included.
This part fits the following models:
The unique design of these JCB mini excavators has sprockets at both ends of the machine. One sprocket is bolted to the drive motor, however this sprocket idler is a combination of a bearing driven idler wheel and a sprocket with drive teeth. We do not currently offer the bearing for this sprocket idler. Please note there are two different types of bolt-on sprockets for this series in addition to this sprocket idler. The 233/21201 (9 bolt) and 331/56572 (12 bolt) are the other versions of the sprocket located on the opposite end of the machine.
We also carry the top roller, bottom roller, and sprocket for these models.
