Komatsu D21a front Idler

dimanche 27 novembre 2016

I just lost the track on my Komatsu D21a.
i found a leaking adjuster seal not holding the track in adjustment and a bad front Idler wheel bearing, not seized but extremely loose.
Can i replace just the bearing or do i have to replace the whole idler wheel assembly?
