Viking (Stihl) iMow 422 front wheel replacement

Firstly, the audio is terrible and I do recommend headphones so you actually can hear what I’m trying to say. Sorry for that.

This is a quick run down of why and how to change the front wheels on your Viking iMow MI 422/422.1
(This can also be applied to the early Stihl iMow RMI 422.0 but you usually only need the bushings on those and from Stihl iMow RMI 422.1 it’s bearings instead of bushings and you can’t pull those out before opening the machine up and removing a locking clip.)

If you don’t have the bushings in your machine then you have a iMow made before 2016 that does not have the updated lower chassi, if thats the case you also have to replace the entire lower half of the chassi, not hard but a bit time consuming.

The complete repairkit for the front wheels have article number 63010071002 and can be bought from any STIHL dealer.

If you only need new bushings they have article number 63090071091.

And If you have an iMow 632 then go check this video :

Usual disclaimer, this is not a definitive how-to, if you brake something it’s on you.
