In order to assess the quality of Komatsu parts, one has to keep in mind that all parts are not equal. Authentic Komatsu units come with specifications that guarantee their proper working condition. Such parts are subjected to stringent quality controls with the right parameters which is not always the case from OEMs who have relaxed standards. because of this, customers should not buy generic parts and use genuine parts as they will ensure a better running time of the machines and better reliability and performance. over time, this will greatly increase the cost-effectiveness of the machinery.
