A critical drivetrain component – a brand new NEXGEN sprocket. Designed for JCB JS series tracked excavators, including models JS210, JS220, JS240, and JS260. The sprocket is precision-made from high-grade, induction-hardened cast steel to ensure maximum service life and wear resistance. It is responsible for transferring power from the final drive motor to the track chain.

The list above is for reference. We recommend verifying the tooth count (21T) and bolt hole count (22H) before purchasing.
Before working on the undercarriage, ensure the machine is on stable, level ground and is properly secured against rolling. Always follow the service manual procedures for releasing and re-tensioning the tracks.
The sprocket is one of the key wear components of a track undercarriage. It transfers power from the final drive to the chain, setting the machine in motion. A worn sprocket leads to accelerated wear of the entire undercarriage.

Pitch is a key dimension of a track chain, measuring the distance from the center of one pin to the center of the next link pin. The sprocket must have an identical pitch to the chain to mesh correctly. This model has a 190 mm pitch.
2. Can I replace just one sprocket?This is highly discouraged. The new sprocket will have a different working diameter than the old, worn one on the other side. This can cause the machine to "pull" to one side when tracking straight and will cause uneven wear on both tracks and final drives. Always replace sprockets in pairs.
3. Will this sprocket fit a 3CX backhoe?No. This product is an undercarriage component for a tracked machine. It is designed for large JS series excavators (JS210-JS260). The 3CX and 4CX are wheeled machines and do not use sprockets.
