For this 3.5 ton Kobelco excavator it came around the 3000 hour mark.
Accompanied with the usual loss of traction, it was very uncomfortable to drive,
There was this continual crunching, and it felt like even on a smooth surface that every 3 feet you were driving over a brick
Old tracks off - and a quick squirt with the pressure washer to clean everything up!
A lick of grey paint with the spray gun - like a girl putting on some makeup in the morning -makes everyone happier.
Old track and sprocket, notice the new sprocket? Spot the problem for a bumpy ride?
The old sprocket is so worn that it no longer meshes with the track causing the crunching sound.
Every now and then one of the sprocket teeth gets miss aligned with the track web and rides high on the web, giving the feeling you have just ridden over a brick.
Profile of the new sprocket.
Job done! the old girl looks a million dollars again!
Amazing what some lipstick and a new set of tracks can do.
