Description / Abstract:
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.
Purpose—This SAE Information Report is an
introduction to lubricant classifications, specifications, and
types in common use today. It emphasizes the desirability of using
a minimum number of lubricants. Pertinent SAE reports are called
out for easy reference. Lubricant abbreviations have been included
that will assist in preparation of lubrication charts (described in
SAE J753).
Rationale—SAE J754 was last revised in January
of 1972. It contains requirements that cut across several
technologies, including engine oil, transmission fluid, hydraulic
fluid, brake fluid, and others. An informal survey of end users and
oil marketers resulted in no interest in this document or in the
technology that it describes. There has also been little or no
buying activity as evidenced by SAE document records. In addition
to TC-3 membership, TC-1 has also been polled for their opinion.
They concur that the document no longer serves a useful purpose and
efforts to update it would not be productive.
