The RC348-21302 idler carries over to the U25 series after several years of reliable service on the KX71-3 series. We have carried this reliable idler for many years and now we offer it for the U25-3 and U27-4 series. This is the aftermarket replacement tensioner idler wheel for the following Kubota mini excavators:

  • Kubota KX 71-3
  • Kubota U-25 / U25-3
  • Kubota U-27-4

The idler holds the track in proper alignment and guides the track in an out of the track rollers. Together they support the weight of the machine and provide a way to control track slack and tension. This idler comes fully assembled with the bearing and mounting arms but does not include the tensioner. The idler is shipped as pictured.


This is the complete replacement idler for these machines. The part is as pictured and comes with arms as a complete unit. No assembly required. This idler has a sealed bearing and requires no maintenance for the life of the product and comes with a standard manufacturer warranty.
