every incident; however, the repair direction will depend on only a few key criteria.
Previous versions of this document provided specific repair directions according to the vintage
of the fuel pump and type of pumping plungers. Repair directions have now been made
common and apply to all fuel pumps regardless of vintage, pumping plunger type, or tappet
roller assembly type.

Preliminary Inspection and Repair Direction for all Fuel Pump Malfunctions
Inspect and verify the condition of the fuel pump tappet rollers. Reference Figure 2 above and
Procedure 005-227 in Table 3 below.
Scenario 1: The fuel pump tapper rollers are damaged:
Remove, cut open, and inspect the lubricating oil filter for debris. See Procedure 007-083
in Table 3.
Connect INSITE™ electronic service tool to the service tool data link and review any
logged fault codes.
Reference Table 1 below for repair direction.
Scenario 2: The fuel pump tappet rollers are not damaged:
Connect INSITE™ electronic service tool to the service tool data link and review any
logged fault codes.
Reference Table 1 below for repair direction.

CAUTION
Immediately upon removal of the lubricating oil cooler assembly, a plug must be inserted
into the housing and cylinder block oil passage drillings. Failure to insert the oil passage
plug can result in a bearing failure, crankshaft failure, or both.
CAUTION
Do not allow dirt or foreign material to enter oil passages in the cylinder block when cleaning
the gasket sealing surfaces. Connecting rod bearing failures can be caused if debris is
introduced into the cylinder block or lubricating oil cooler housing oil passages. Therefore,
use of power tools combined with abrasive pads to clean gasket surfaces is not
recommended.
Repair Direction A:
1. Replace the fuel pump. Table 2 below must be referenced for specific instruction by
product type. See Procedure 005-016 in Table 3 below.
2. Drain the lubricating engine oil. See Procedure 007-037 in Table 3.
3. Thoroughly clean the lubricating oil cooler housing. See Procedure 007-003 in Table 3.
4. Replace the following lubricating oil system components:
Lubricating oil cooler element. See Procedure 007-007 in Table 3.
Lubricating oil filter bypass valve. See Procedure 007-014 in Table 3.
Lubricating oil thermostat. See Procedure 007-039 in Table 3.
5. Remove the lubricating oil pan, and clean thoroughly. See procedure 007-025 in Table 3.
6. Remove and inspect the lubricating oil pump for reuse. See Procedure 007-031 in Table
3.
7. Remove number 1 and number 4 main bearing caps and main bearings. See procedure
001-006 in Table 3.
8. Inspect number 1 and number 4 main journals of the crankshaft for reuse. See Service
Bulletin Crankshaft Reuse Guidelines for Cummins® Engines, Bulletin 5411180.
If the crankshaft meets reuse guidelines:
Inspect number 1 and number 4 main bearings for signs of significant debris
https://qsol.cummins.com/qs3/pubsys2/xml/en/tsb/2014/tsb140019.html

embedding. If significant debris is found, remove the number 1 and number 4
connecting rod bearings for inspection.
If damage is observed on the number 1 and number 4 connecting rod
bearings, roll new connecting rod bearings in on all 6 journals. See Procedure
001-006, 001-007, and 001-014 in Table 3.
Roll new main bearings in on all 7 main journals and install new thrust
bearings on number 4 main journal.
If the crankshaft does not meet reuse guidelines:
Dealers should contact RAPIDSERVE™ Catastrophic group for preauthorization if the engine is under warranty.
Cummins® Distributors should follow their local catastrophic process or
contact RAPIDSERVE™ for repair direction if the engine is under warranty.
Install the lubricating oil pan and other components removed to access main bearings.
See procedure 007-025 in Table 3
Install a new lubricating oil filter. See Procedure 007-013 in Table 3.
Prime and fill the engine with new lubricating oil. See Procedure 007-037 in Table 3.
Perform an aftertreatment diesel particulate filter (DPF) regeneration. See Procedure
014-013 in Table 3.
Perform a second lubricating oil and lubricating oil filter change. Priming the lubricating
oil system a second time is not required. See Procedure 007-013 and 007-037 in Table
3.
