Excerpt from Comparative Test of Cylinder Lubricating Oils: A Thesis The next failure of the piston was as before, in the cast-iron ring. The grooves had been out almost through the ring, separating it into three parts each.about one-quarter of an inch wide. Each one of these parts cracked where the pin had been driva enin it and no longer held the piston rings parallel to each other? To overcome this diffivulty, the solid ring was discarded and a new casting made. The spider was turned down to secure a thicker ring, which was shrunk on as before. Grooves were out in the ring, end the snap-rings and brass plate replaced. This piston seemed to work fairly well and we hoped that it would give results when worn in.
