What JCB 803 undercarriage parts does VANROCK supply?

Expert Answer

For the JCB 803, VANROCK supplies the undercarriage parts most commonly needed for track wear and replacement: segment group VRTR260300 (14.20 kg), rubber track VRT300X52.5X84W (131.00 kg), track roller with one flange VRTA260300 (7.50 kg), track group VRTL1430B243300 (179.50 kg), and carrier roller VRTC260300 (4.00 kg). These parts are the verified VANROCK records for this model.

If you are matching a replacement, check the machine model exactly and compare the worn part type before ordering. On a JCB 803, the key points are whether you need a complete track group, a single rubber track, or separate running-gear components such as rollers or sprocket segments. Wear patterns on the track, rollers, or segments can help confirm what should be replaced together.
