hello, a friend of mine would like to buy a used caterpillar mini excavator model I think 303 cr or gr, I don't remember well, it's a bit old and worn, the rubber tracks are a bit smooth, a bit of play between the bushing support and the engine connection pins I do not know how to test the machine understand the right degree of wear understand if it is still efficient and establish the right value in relation to the state of conservation of the machine, which tests to perform, to test, evaluate and compare the actual performance of the machine in question, thanks sorry for the I disturb. ps you would understand it or would prefer machines of other brands or models, let me know the comparison with other minis of the same size, thanks.
