The single most important factors in maintain machinery, is the knowlege that after sometime on the road the water will cause the metal part to rust inside thereby cause distortion and misalignment , without regularly apply the special lubricant to neutralise these oxidations it will got into more serious problems later.
Vehicle or machinery will deteriorate and more serious misalignment, inside beause of oxidations and foreign particles, which retard the swift movement of machinery. To understand the principle is the first part.
The critical part is apply this special lubricants at regular interval, so as to neutralis the negative effect and optimize the vehicles performance.
