SO as to plainly mark where the connecting-rod brasses of bead end require easing; and after the cross- head end is adjusted, put the crank-pin of the rod upon its place upon the crank-pin, keeping the cross-head end clear of the cross-head; put the brasses, keys, etc., in their places, and proceed as before. Red marking should be rubbed on both the crank-pin and cross-head journals, so as to mark the brasses plainly. A half-round file and half-round scraper should be used to adjust and ease the brasses.
