Part Number: 331/30581
Alternative Numbers: 331/20054
Type: Idler Wheel

This idler wheel is designed for JCB mini excavators in the 5–6.5 ton class, including popular models 8052, 8055, 8056, 8060, 8065. It ensures proper track guidance and works in conjunction with the tensioner to maintain correct track tension.

High-quality construction guarantees wear resistance of the running surface and core strength under impact loads, even under the most demanding operating conditions. A properly functioning idler wheel significantly extends the lifespan of the entire tracked undercarriage.

 

Function and Fault Diagnostics

The idler wheel is a critical component of the undercarriage. Its main functions are:

  • guiding the track on the undercarriage frame,

  • maintaining correct track tension in cooperation with the tensioning system.

Signs of wear or failure include:

  • excessive wear of the running surface, causing the track to slip off,

  • cracks in the wheel, usually due to impact or material fatigue,

  • damaged or seized bearings (wheel does not rotate smoothly, makes noise),

  • inability to correctly tension the track.

⚠️ Safety Warning

Working on a tracked undercarriage is extremely dangerous. Before removing or installing the idler wheel:

  • fully release the track tensioner (relieve grease pressure),

  • securely support the machine on certified stands,

  • exercise extreme caution while handling the track.
