Yanmar 172173-29100 Sprockets

This is the replacement sprocket 172173-29100 for the following Yanmar mini excavator models:

  • Yanmar VIO 20-2
  • Yanmar VIO 20-3

Sprockets should be changed at the same time you change rubber tracks. If you install new sprockets on used rubber tracks you may cause a premature failure since the alignment of the drive teeth and the track links will not line up properly. The track will end up sliding up and down the drive tooth as opposed to gently applying the proper torque to rotate the track. We always suggest installing rubber tracks and sprockets at the same time to extend the lifespan of both parts.

There is one drive sprocket per side on your Yanmar VIO20-2 and -3 series mini excavator.

There are several newer sub-series of VIO-20 models so if your model is newer than a -3 series then please verify with us prior to ordering online.

Yanmar Sprockets

Smaller sprockets for Yanmar mini excavators are hardened in a one step procedure via electrical induction. This increases the depth of the hardness through the teeth while preventing breakage. Our aftermarket sprockets are hardened within millimeters of the original OEM sprocket which provides great value for our customers overall. We recommend installing by hand to your manufacturer's suggested torque specifics.
