This document, in conjunction with the information provided within the manuals listed in the
table above, provides the inspection and repair practice when ceramic plungers are found to
be fractured (see Figure 1) and/or tappet roller damage is found on fuel pumps with ceramic
plungers (see Figure 2). Ceramic plungers can be identified by their white color. Refer to
Procedure 005-227 in the Associated Procedures Table for removal of the fuel pump head.

If the ceramic plungers are fractured (see Figure 1), but no damage is found on the fuel pump
tappet rollers (see Figure 2), no further inspection is needed. Perform the following steps for
the appropriate engine (ISX15 CM2250 or QSX15 CM2250 ECF):
1. Replace the fuel pump. Refer to Procedure 005-016 in the Associated Procedures Table.
a. Refer to TSB110064 (New Two-Cylinder High-Pressure Fuel Pump Assembly) if
replacing a three-cylinder two-piston pump with a two-cylinder pump.
b. New fuel lines are required if replacing a fuel pump gear pump with bottom mount
fuel lines. Refer to TSB130044 (New Fuel Pump Gear Pump with Revised Fuel
Line Locations).
2. Change the engine lubricating oil and lubricating oil filter. Refer to Procedure 007-013 in
the Associated Procedures Table.
If the fuel pump tappet rollers are damaged (see Figure 2), perform the following steps for the
appropriate engine (ISX15 CM2250 or QSX15 CM2250 ECF):
1. Replace the fuel pump. Refer to Procedure 005-016 in the Associated Procedures Table.
a. Reference TSB110064 (New Two-Cylinder High-Pressure Fuel Pump Assembly) if
replacing a three-cylinder two-piston pump with a two-cylinder pump.

Line Locations).
2. Drain the engine lubricating oil and remove the lubricating oil filter. Refer to Procedure
007-013 in the Associated Procedures Table.
3. Thoroughly clean the oil cooler housing. Refer to Procedure 007-003 in the Associated
Procedures Table.
4. Replace the lubricating oil cooler element. Refer to Procedure 007-003 in the Associated
Procedures Table.
5. Replace the oil filter bypass valve. Refer to Procedure 007-014 in the Associated
Procedures Table.
6. Replace the lubricating oil thermostat. Refer to Procedure 007-039 in the Associated
Procedures Table.
7. Install a new lubricating oil filter. Refer to Procedure 007-013 in the Associated
Procedure Table.
8. Fill the engine with new lubricating oil.
9. Perform an aftertreatment diesel particulate filter regeneration. Refer to Procedure 014013 in the Associated Procedures Table.
10. Perform a second lubricating oil and lubricating oil filter change. Refer to Procedure 007013 in the Associated Procedures Table.
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.
