How To Distinguish Between Old And New Diesel Generator Sets

In the selection of diesel generator sets, distinguishing between old and new is a prerequisite for purchase. A small number of unscrupulous merchants use old parts to assemble or refurbish equipment. Learning to distinguish between old and new sets can help everyone block out some unscrupulous merchants. So, in our daily operations, what aspects can we use to distinguish the old and new equipment of the unit? I have summarized the following points for everyone:
The age of a generator set can generally be determined by simply touching, looking, and testing it. The test marks of a new generator set are quite obvious, except for the exhaust pipe and turbocharger where there are not obvious signs of use, but not very deep. All the parts inside the old machine will have traces of use, especially the fan belt of the generator. The fan belt of the used generator set is severely worn, and it can be seen at a glance that the two are completely different.
So, when purchasing a diesel generator set, do not assume that the generator set is old just because you see a trace of use on the turbocharger and exhaust pipe on the generator. This is completely unfair to the manufacturer. Everyone should try to choose reputable and trustworthy brands when purchasing, and not fall into the trap of low prices, which may lead to buying inferior equipment.
