This Hitachi ZX225 excavator comes into the workshop with a failed front idler, but once the undercarriage starts coming apart it’s clear there’s more going on than normal wear and tear. Used in rental and dry hire work, this 23 tonne machine shows exactly what can happen when equipment gets pushed hard. After inspecting both sides, one idler has already been replaced with the wrong part, and the other has deteriorated massively in just one month. To carry out the repair, track tension is released through the recoil assembly so the track plates can be moved and the master pin accessed. Once the pin is driven out, the track chain is separated and the idler and recoil assembly are lifted clear using the overhead crane. New idlers are installed, everything is reassembled, and the tracks are tensioned back up through the grease system to bring the undercarriage back into proper working order. What stands out most is just how quickly the damage progressed… and how much worse it looks once everything is removed. To find out what really happened, the failed idler is cut open at the end to reveal the internal damage. This is a solid example of why proper parts and regular inspections matter on machines like this. Join our channel: We upload new videos every Friday at 5pm AEST!
