also these parts sometimes wear out within weeks on installing them i think i did a change on 2 crusher pads within 3 weeks... the bushes not so much, but there also a part that if not looked after companies dont just have spares laying around, for eg. (sorry for all my stories) I went to a site the pinion had cracked there were none in Australia, the next available one would have got there in 4-5weeks, instead of waiting they took 6 days to escort another crusher to site now not only is that alot of money in transport and downtime but thats another half a million dollar machine needing to be used because there was no part available, these machines earn anywhere from $120-$300p/hr and now this company had one down for 5 weeks and took another one off another job... now if A3D could print this pinion it would take about 2-3days to replace
