PIN AND SPACER GROUP 7S7671 - Caterpillar

The various Marine Classification Societies require a supply of replacement parts on vessels that are primarily powered by diesel engines. The replacement parts may be needed for making repairs offshore or at remote ports. The types of replacement parts and the numbers of parts depends on the range of the vessel. The following two categories of vessels are considered:Category 1 - This category includes vessels that make short trips between ports.Category 2 - This category includes vessels in ocean service that is unrestricted. The vessels may travel far from ports that provide service. The list of replacement parts for this category is more extensive.Table 1 lists the parts that are recommended by Caterpillar for vessels in both categories.The requirements of individual Marine Classification Societies may differ. Table 2 lists the requirements of all the Marine Classification Societies. Additionally, some items that are recommended by Caterpillar are listed. All of the parts that are listed in Table 1 and 2 are recommended for vessels in Category 2. To customize this list for your specific engine application, consult your Cat dealer.Note: Check with your local class society for any questions regarding the onboard replacement parts.
