12、1 RATIONALEX1.1 In 1986, Eaton Corporation, through the Society forAutomotive Engineers (SAE), outlined the trucking industrysindustrysneed for a gear lubricant category whichthat would provide performance characteristics essential to ensure optimum service lifefor heavy-duty manual transmissions. T

13、his request was supported by all major North American commercial transmission builders.X1.2 During the same period user surveys indicated that the class of oils typically used in manual transmissions was not alwaysin compliance with the builders primary recommendations. API GL-5 gear oils or multigr

14、ade engine oils were the popular choiceof users due to their desire to inventory and use two shop oils, engine and gear. Some of these oils were found to performsatisfactorily while others presented problems. In extreme cases, some API GL-5 oils were reported to cause oil seal failures dueto coking/

15、hard deposits or severe oil sludging at mileages below realistic drain intervals, or both.X1.3 Using feedback from equipment builders, SAE outlined several lubricant performance characteristics whichthat theybelieved were vital to ensure that their goals for optimum transmission service life would b

16、e met. These characteristics includedthe following:(1) Fluid thermal stability/component cleanliness,( 2) Oil seal compatibility, and(3) Brass (copper) component compatibility.X1.4 ASTM was then requested to identify or develop tests suitable to assess the preceding performance characteristics. In t

17、heprocess, the proposed categorys performance test matrix was expanded to include properties in addition to those originally definedin order to ensure that a performance balanced lubricant would be provided to users. The added properties included antiwear, foamcontrol, and lubricant compatibility. A

18、 full-scale transmission test was also included to reaffirm the high-temperature lubricantperformance capabilities of API Category MT-1. This test correlates with field service and also ensures satisfactory performancewith plate-type synchronizers.X1.5 The tests and acceptance criteria defined by th

19、is specification are the result of specification and test method developmentwork withinASTM. The introduction of this new category will allow OEMs to specify gear oils for manual transmissions that canbe made available either as dedicated fluids (API Category MT-1) or multipurpose fluids (that is, A

20、PI GL-5/API Category MT-1).Oils meeting the API Category MT-1 performance definition will satisfy OEM objectives for optimum transmission performanceand service life. This has been achieved by combining in a single lubricant the cleanliness and oil seal life typical of engine oilswith the load carry
