This is the aftermarket replacement front tension idler for Kubota 121-2 and 121-2SS mini excavators.

This idler is a complete assembly with mounting brackets. The idler must be replaced to keep the track tensioned properly when significant wear is present. If you run on worn idlers the track will lose tension and many other problems will occur. Keep your track tensioned properly by greasing the tension idler into place and check the tension daily and evaluating the wear on the sprockets and idlers. Uneven wear will result in premature track damage. You will see the best results and longest lifespan of the undercarriage if you maintain the tension and replace wear parts simultaneously.
