Now that you know that you must absolutely try out a piece of used Caterpillar heavy equipment before actually making a decision to purchase, you may notice some heavy sounds coming from the machine. Noises could either mean damage in the rear of the machine, or damage in the external parts. If you cannot put a stop to such a huge machine, you would be headed for disaster, literally. If the damage is in the external parts, then you would be able to repair it at a cost that would be considered as insignificant. You would of course not want to purchase cat parts that have undergone bad maintenance. Caterpillar Parts heavy equipment has been known to last for more than forty years, so age really does not matter all that much. Pay close attention to the outer layer of the cat parts also. Rusts can be dealt with rather easily, but it could be hiding something far more sinister and ominous underneath. However, if the heavy equipment is not maintained properly, it would severely lessen the age of the equipment, and you may end up having to pay a lot of money for proper maintenance to get it back into shape.
