Essential for Installation

  • › Mounting Bolts (22 pcs): Always use new, high-tensile bolts to mount the sprocket to the final drive.
  • › Torque Wrench: Required to tighten the bolts to the correct manufacturer specification.

Application in machines

Brand Type / Series / Model
JCB Tracked Excavators: JS210, JS220, JS235, JS240, JS260

The list above is for reference. We recommend verifying the tooth count (21T) and bolt hole count (22H) before purchasing.

⚠️ Safety Warning

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.

Part's Role in the Machine and Failure Diagnostics

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.

  • › Sharpened tooth tips ("shark tooth" profile).
  • › Track "jumping" or "skipping" when turning or under load.
  • › Damage to the track chain bushings (due to poor meshing with the worn sprocket).
  • › Loose bolts fastening the sprocket to the final drive (risk of shearing).

🔧 Expert's Guide: Key Installation Tips

  1. Replace in pairs: Sprockets should always be replaced in pairs (left and right) to ensure even wear and proper tracking of both chains.
  2. Replace with chains: Installing new sprockets on old, stretched track chains is not recommended. It will cause accelerated wear of both the new sprockets and the old chains.
  3. Clean the mounting surface: Thoroughly clean the mounting surface on the final drive of all rust and dirt before bolting on the new sprocket.
  4. Torque Specifications: Use a torque wrench and tighten the mounting bolts in a star pattern to the manufacturer's specified torque.

Frequently Asked Questions (FAQ)

1. What does "Pitch 190 mm" mean?

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.
