An improved cylinder pack has been released for engines that are used in high load applications that are listed above. The improved cylinder pack contains a top piston ring that is made from stronger materials. The stronger materials have a proven robustness in order to withstand fatigue, due to high load applications. High load applications include coal and logging applications. High load applications also include any application with a Gross Vehicle Weight Rating (GVWR) that is equal to or greater than 63,500 kg (140,000 lb). For the high load applications, refer to Table 1 when cylinder packs are being replaced. Replace the top ring on the remaining cylinders with the 247-6130 Top Piston Ring .
