This instruction is therefore confined to listing specifications for particular lubricants which we have learned from experience are best suited to the application.

tE>>>>j DIESEL ENGINE OIL QUALITY It should be recognized that the only real measure of quality in a lubricating oil,is its actual performance in the diesel engine. This is so because of the impossibility of establishing limits on all physical or chemicalproperties of oils which can affect their performance in the engine. The responsibility for recommending and consistently furnishing a suitable heavy-duty oil must rest with the individual oil supplier.. OIL TYPE An SAE 840 heavy-duty additive type lubricating oil, which conforms to the following specifications, should be used in all engine applications. Physical Properties ASTM Designation Limits Saybolt Universal D88.or D446 r

The oil should be a heavy-duty additive type having a high resistance to oxidation, a low tendency toward the formation of carbon deposits, and shall be noncorrosive,to silver metal at 285'. The silver corrosion evaluation should be made according to EMD laboratory test method WL.O. 201 (latest revision).

~ ~ M.1. 1752 We strongly recommend that zinc dithiophosphate or similar additives not be present in the engine lubricating oil. Oils containing more than 10 ppm zinc are considered excessively contam inated with zinc dithiophosphate additive and should not be used since they may not satisfactorily lubricate the reciprocating bearings used in these engines. MDZNG OP OII S Our recommendation against mixing different kinds or brands of heavy-duty oils is

    ~antially supported by numerous recorded cases where various mixtures of in-coxnpatible oils were detrimental to engine operation. Unfortunately, expensive failures or abnormally high wear rates caused by incompatible oil mixtures cannot be predicted
 .
   'y  laboratory procedures.

Tbe mixture of oils usually results in a lubricant that: is less stable than any of its constituents. Sludge and lacquer formation caused by this instability results in exces-sive wear and in shorter oil and filter life. Ordinary laboratory techniques cannot be used to analyze samples of lube oil mixtures because it is impossible to establish a starting base line condition against which to measure the level cf oil deterioration. As aresult, problems caused by. unsatisfactory 1ubrtcation.are difficult to diamose when using an oil mixture. OIL'HANGES I Engines intended for export, marine, industrial, or other special installations me often treated with rust preventive material which'eed not be removed. Oil meeting the specifications given should be used when placing the units in service. This oil should be changed and the lubricating system maintained as specified in the applicable Scheduled Maintenance Program. Laboratory analysis may dictate oil changes at shorter intervals than those specified in the Scheduled Maintenance Program. The oil change intervals pre'scribed in the applicable Scheduled Maintenance Program are based on average operating conditions. YVhen oil change intervals are extended, serious and costly engine problems usually result. This occurs when the heavy-duty lubricating oil loses its detergent-dispersant properties, allowing partially oxidiied oQ and other contaminants to form deposits in the engine. I Replacing old oil with a fresh charge of heavy-duty oil in a contaminated engine will result in the new oil pickingup some of these deposits and rapidly losing its detergency and dispersancy. KVith the oil losing these properties quickly, and with continued opera-tion, the deposits will become progressively worse and w01 ultimately lead to serious engine problems. Laboratory analysis should not be used as the only guide to the condition of a lubricating oil. Of equal importance is the condition of the engine, which could be poor even though the oil appears satisfactory. Both engine and oil condition should be considered when attempting to arrive at oil change intervals'beyond those recommended.

M,I, 1752 FILTER CHANGES Oil filter element replacements should bemade as specified in the applicable Scheduled Maintenance Program, unless a laboratory lube oil analysis dictates earlier replace-. ment. Where highly dispersant oils are employed, carbonaceous mattermay be suspended so finely in the oil that it is essentially unfilterable. In such situations, it might appear that an extension of the filter element replacement,interval would be practical. Caution be exercised when contemplatingsuchaction. Filtermaterials have not yet been 'hould developed to tolerate prolonged exposure to lube oil without deterioration and possible disintegration of the filter elements. OIL DILUTION Engines, found to have lubricating oil diluted with fuel oil should be serviced in the following manner:

1. Prom 0 to 3% dilution Within this range there is generally no need for concern or corrective action.

2. Prom 3% to 5% dilution Engine operation may continue until the next scheduled shutdown, provided total dQution does not exceed 5%. However, repairs should be made as soon as practical.

3. Above 5% dilution When dilution exceeds 5%, the engine should be removed from service untQ the fuel

   )eak is repaired and the oil is changed.

GOVERNOR An SAE 20W-40 oil which will meet American Petroleum Institute (A.P.I.} Engine Performance Evaluation DG or MS is recommended for -all governor applications.

Measuxe the temperature of the generator bearing by applying a surface pyrometer to the outside of the bearing cover, The temperature measured should not exceed a 25 C rise above the room ambient temperature. If the temperature is greater than 25'C rise, immediately notify the ASE running the diesel and the electrical maintenance supervisor. Record both the bearing temperature and the room ambient temperature on the trouble report. Also, record the diesel running time on the trouble report for informational purpose. Upon receipt of the trouble report in the electrical maintenance office, the information will be transferred to data sheet EMI 3-A. A data sheet BP EHI 3-A will be 'kept for each diesel generator. General Instructions-Bearing Inspection Clearances An EHI will be written at a later date to cover the diesel generator bearing inspection. It will contain the necessary cleaxances. Inspect the generator bearing in accordance with the guidelines in the manufacturer's manual EMD MI 3327. There is only one bearing in the generator and it is located at the outboard end of the shaft. The bearing is a sealed grease lubricated, double row, spherical, self-aligning type and there should be no need for additional lubrication during the generator's life. Two conditions, a high bearing temperature or excessive noise in the outboard end of the generator, may warrant a bearing inspection in advance of the normal 9000 hour inspection.

Page 3 BF EMI 3 12/14/76 Maintenance Items (Continued) B. Generator Brushes generator brushes for sparking. Clearances None required. The generator brushes and slip rings are checked thoroughly during the diesel annual inspection and need only a 1 visual check once a month. During the performance of SI 4.9.A.l.a., observe the generator brushes. If any sparking is noticed, immediately notify the ASE runnidg the diesel and the electrical maintenance supervisor. Observe the length of each. brush and if any brush appears to be approximately one-inch long, notify the electrical maintenace supervisor. Note on the trouble report whether any sparking was observed and wh whether the brushes are of acceptable length. Upon receipt of the trouble report in the electrical maintenance office, the information will be transferred to data sheet BF EMI 3-B. A data sheet BF EMI 3-B will be kept for each diesel generator. General Instructions-Brush Changeout a4 The clearances required for SI 4.9.A.l.d.

b. The exciter field breaker.

When any brush reaches a length of 1 inch + 1/8 inch, change all four brushes on that generator. When installing new brushes, sand them to fit the curvature of the slip ring by placing a piece of sandpaper on the surface of the ring with the grit side against the brush. Then, with the brush held down by the pressure arm of the brush holder, move the sandpaper in the direction of rotation of the rings. Repeat the motion until the brush fits the curvature of the rings. Run the diesel per SI 4.9.A.l.a steps 3.5.a through 3.5.g (DO NOT PLASH THE PIELD) for one hour. Stop the diesel and inspect the brushes and repeat the diesel run as necessary until the brushes are seated on between 50% and 80% of them surface. Document the changeout of the brushes on the trouble report issued to accomp1ish the worst.

The following table lists the required surveillance items regarding this section: Table 4.9.A.l.a - Surveillance Re uirements

     ~Pre uanc                         Re uirement Monthly                           Each  diesel generator manually started.

Each diesel generator loaded for at least 1 hour at 75/ rated load or greater. Diesel generator starting air compressor checked for operation.

                                      .Diesel fuel oil transfer      pumps checked for operation.

Diesel generator starting time logged. The monthly diesel generator tests will provide information as to the condition of the diesel engines, the generators, and their associated equipment. Included in these tests are the operability of the starting air systems, the fuel oil systems, the diesel generator starting circuitry, and the diesel generator load control circuitry. In ox'der to check all staxting situations, othex surveillance tests may be incorporated into this test to pxovide starting signals to the diesel generators. These other surveillance tests are the Common Accident Signal Logic.

This test provides verification that each diesel generator wi11 start and accept its assigned emergency load when called upon by a simultaneous loss of shutdown power and an accident signal. In addition to this verification, data will be taken to check the stability of each diesel generator under severe load transients. From test to test comparisons can be made to detect any significant changes in each diesel geneiator's characteristics under these conditions. Since this test concerns'the operation of the diesel generators and not of the ECCS equipment, this test for units 1 and 2 will be conducted using only unit 1 equipment as the loads. The test is written to test each diesel generator individually without hindering i or altering the other diesel generators'bility to function.
