6/1/2021 Lubricating Oil Consumption in Low Load and High Idle Applications Technical Service Bulletin Technical Service Bulletin: TSB200110 Released Date: 27-May-2021 Lubricating Oil Consumption in Low Load and High Idle Applications Lubricating Oil Consumption in Low Load and High Idle Applications Warranty Statement The information in this document has no effect on present warranty coverage or repair practices, nor does it authorize TRP or Campaign actions. Contents Product Affected Engines: L9N CM2380 L124B L9N CM2380 L130B L9N CM2380 L142B ISL G CM2180 (Only engines equipped with steel pistons) Application: Transit Bus 280 horsepower (L9N CM2380 L124B and L9N CM2380 L142B) Transit Bus (L9N CM2380 L130B) Yard Spotter School Bus Issue https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2020/tsb200110.html 1/5 6/1/2021 Lubricating Oil Consumption in Low Load and High Idle Applications Engines operating in a low load and high idle duty cycle may experience oil consumption above published specification limit in Lubricating Oil Consumption and Acceptable Limits, Service Bulletin 3379214, and fault codes associated with high EGR temperature. Root Cause Obsolete piston rings were unable to fully seat with the cylinder liner with insufficient time (break-in period) under low load. Verification For ISL G CM2180: Verify if CPL is 5232 on the engine dataplate. If not, review engine service repair history to determine if the engine is built with or upfitted with steel pistons. For engines prior to engine serial number (ESN) 74765136, review engine service repair history to determine if the engine is equipped with the obsolete piston rings. Verify if the engine is equipped with obsolete piston rings: Table 1, Obsolete Piston Rings Part Number Engine Description Obsolete Part Number Compression Piston Ring (Top Ring) 5364466 Compression Piston Ring (Intermediate Ring) 5364467 L9N CM2380 L124B L9N CM2380 L130B ISL G CM2180 L9N CM2380 L124B L9N CM2380 L130B ISL G CM2180 The part numbers in table 1 were part of the obsolete kits mentioned in table 2: Table 2, Obsolete Kits Part Numbers Description Piston Ring Kit (single cylinder) Obsolete Part Number Content 5406026 1 x Expander Ring 2 x Oil Ring 1 x Top Ring 1 x Intermediate Ring https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2020/tsb200110.html 2/5 6/1/2021 Lubricating Oil Consumption in Low Load and High Idle Applications Table 2, Obsolete Kits Part Numbers Description Overhaul Kit Obsolete Part Number Content 5633416 6 x Piston Kit 6 x Cylinder Liner 6 x Piston Ring Kit 12 x Connecting Rod Bearing 1 x Lubrication Oil Filter 1 x Fuel Filter 1 x Lower Engine Gasket 1 x Upper Engine Gasket 1 x Spark Plug Kit 1 x Oil Cooler Core Confirm that any of the following fault codes are present: High EGR Temperature Fault Codes: 2961: Exhaust Gas Recirculation Temperature - Data Valid But Above Normal Operating Range - Least Severe Level 2962: Exhaust Gas Recirculation Temperature - Data Valid But Above Normal Operating Range - Moderately Severe Level Verify oil consumption is greater than the amount outlined in Lubricating Oil Consumption and Acceptable Limits, Service Bulletin 3379214 Verify the EGR cooler is fouled or plugged . Reference Service Bulletin, EGR Cooler Reuse Guidelines, Bulletin 2883594. Resolution Follow the troubleshooting for Lubrication Oil Consumption in the Fault Code Troubleshooting Manual. If no resolution is found, repair the engine using the overhaul kit listed in Table 4 below. Replace fouled EGR cooler. Reference Service Procedure 011-019 EGR Cooler in Section 11.
