New undercarriage parts and rubber tracks are sold individually but we suggest replacing all of your worn parts at the same time.
This is the aftermarket replacement tension idler for the Kubota mini excavators listed below.
This is the larger wheel that tensions the rubber track when you grease the tensioner. It is located on the opposite end of the undercarriage from the sprocket and there is one idler per side, two total per mini excavator. The idler is sold as a complete assembly with the mounting arms and bearing complete as pictured.
Please verify your model on the other undercarriage parts as some do not fit the 41-3V series.
