Action Required
Document oil consumption using the information in Warranty Bulletin No.16 (SEBF 5116-04). Verify that at least the minimum recommended maintenance has been performed by the customer. If excessive oil consumption has been documented and at least the minimum recommended maintenance has been performed, repair the engine using the new parts. ***** Preventive Action For Excessive Oil Consumption ***** Evaluate the engine application for needed corrections. A. Do not overcool jacket water. The jacket water temperature must be kept above 79 deg. C (175 deg. F). Check thermostat for leakage, install orifice or 8N9071 Check Valve in radiator vent line, if needed. B. Check air system for leaks. Abrasive wear can be a factor in excessive oil consumption. Evaluate the engine maintenance for needed corrections. A. It is recommended that only superior quality CD lubrication oils be used. See "EMA Lubricating Oils Data Book" Form SEBU5939 or "Oil And Your Engines" Form SEDB0640. C of A dealers should also refer to "Caterpillar Heavy Duty Engine Oils for Australia", MEHQ1178. B. Oil change intervals are important. The oil should be changed at the intervals shown in the Operation and Maintenance Guide or at intervals that are consistent with your fuel usage compared to oil sump capacity. C. Ensure that the correct Caterpillar oil filter is used. WARRANTY ALLOWANCES Caterpillar's contribution for this Program will be a percentage of the total allowable parts and labor. Calculate the cost of the listed parts at consumer list. A maximum of 20 hours labor at dealer selling rate will be claimable for installing the 6-0R2413 Kits. If individual parts are installed, a maximum of 23 hours at dealer selling rate will be allowed. Other costs, if allowable under standard warranty, can also be claimed. Use the information in the following example to determine Caterpillar's contribution. Calculate the total cost of claimable parts. Assume the cost to be $1200.00 for the example. Calculate the total cost of claimable labor. Assume the cost to be $600.00 for the example. Calculate the total cost of parts and labor. For the example the total would be $1800. 00. Assume there are no other allowable costs. Obtain the mileage and time in service for the engine. Round the miles down to the next lower 10,000 mile interval. Round the time down to the next lower full month. For the example assume 173,260 miles which rounds down to 170,000 miles, and 21 months and 10 days which rounds down to 21 months. Locate the 170,000 miles and the 21 months on the appropriate vertical lines on the attached graph. Using a straight edge connect the two points. Find the point where the straight edge crosses the vertical line "Caterpillar Contribution". For the example the straight edge would cross between the 70% and 80% marks. Use 80% to calculate Caterpillar's contribution. For the example, Caterpillar's contribution would be 80% of $1800.00 which is $1440.00. If the straight edge crosses the vertical line "Caterpillar Contribution" at any point below the 100% mark, Caterpillar's contribution will be 100%.
