Table 1 lists the components of construction and industrial equipment and the various lubricants which may be used. Table 2 lists lubricant types and identifying abbreviations. Lubricants that had common usage in the past are retained in Table 2 to show where the new specifications originated. Original factory lubrication may deviate from field recommendations because of special requirements, such as breakin. Lubricant viscosity grade should be selected for various climatic conditions (described in SAE J300 and SAE J307). The final selection of the lubricant and grade will depend upon the requirements of the equipment manufacturer.
