When the engineer is satisfied that the truck, pilot-braces, center-castings, and all their connections, are in proper condition, he passes on to the motion. His trained eye scans every bolt, nut, and key in search of defects. The eccentrics are examined, to see that set screws and keys are all tight. Men who have wrestled over the setting of eccentrics on the road are not likely to forget this part. Eccentric-straps are another point of solicitude. A broken eccentric-strap is a very common cause of break-down, and these straps very seldom break through weakness or defect of the casting. In nearly all cases the break occurs through loss of bolts, or on account of oil-passages getting stopped up. The links are carefully gone over, then the wedges and pedestal braces come in for an examination which brings the assurance that no bolts are missing, or wedge-bolts loose. Passing along, the careful engineer finds many points that claim his attention; and, when he gets through, he feels comfortably certain that no trouble from that part of the engine will be experienced during the coming trip. The runners who do not follow this practice are not aware of how much there is to be seen under a locomotive when the examination is undertaken in a comprehensive manner.
