Procedure
Camshaft lobe inspection
This inspection process will determine one of the following:
No further repair required.
If the camshaft shows slight wear and the lower main bearings are ok, the engine will be reassembled and released to the customer. An
additional inspection will be made in 200,000 miles (321,868 km) (approximately 6,000 engine hours).
A select group of chassis will be asked to return for an additional inspection at 50,000 miles (80,467 km) (approximately 1,500
engine hours).
Camshaft replacement required.
Long block or complete engine replacement required.
1.

2.

Remove the oil pan and inspect the camshaft exhaust lobes.
a. Disconnect the batteries.
b. Drain the oil.
c. Remove the electrical harness bracket from the driver’s side front of the engine block and oil pan.
d. Use cable ties to hold the harness away from the pan.
e. Remove the oil pan bolts and remove the oil pan.
Refer to the Camshaft Inspection Photo Guide to take clean, clear, and in focus photos of the PEAK of the EXHAUST camshaft lobes. The
exhaust cam lob is the wider lobe.
a. Open the Camshaft Inspection Photo Guide document and save it as a new file. Use the naming convention of “last 8 digit of VIN
Cam Inspection”.
b. After you take the photos, insert the photos into the appropriate open cells of the Camshaft Lobe Photos table.

3.

Start a TCS365 case. See the TCS365 Case Creation Guide section below for instructions to create the case. Attach the Camshaft

Inspection Photo Guide to the case. The Vehicle Support Center (VSC) will analyze the camshaft lobe photos and inform you of the next
repair step.
If VSC directs you that the camshaft is ok, reassemble the engine per RMI and replace the engine oil filter and fill with new oil.
If VSC directs you to inspect the lower main bearings, continue with this procedure.
Remove Main Bearing Cap numbers 3, 4, and 5.
a. Remove the oil pickup tube from the fixing frame.
b. Remove the fixing frame from the engine block.
c. Remove the oil pump.
d. Break loose the main cap bolts with hand tools.
e. Remove the main cap bolts for main bearing journal locations 3, 4, and 5 (an air/electric impact tool can be used).
f. Remove and inspect only the lower bearing shells of 3, 4, and 5. Leave the upper bearing shells in place.
IMPORTANT: Keep the bearings organized. Make note of the location of each bearing. If the bearings look like Ratings 1 or 2, they
will be reused. They MUST be installed in the same location that they were removed from.

5.

g. Place the bearing caps on a clean piece of paper or cardboard and label the bearing locations.
h. Take clear and in focus photos of the bearings.
Inspect the condition of the bearings and attach the bearing photos to the TCS365 case and update the Diagnostic Details of the case with
“inspected and attached #3, 4, & 5 main bearing photos”. VSC will provide final direction of repair.

Unit Pump to High Pressure Fuel Rail Lines
The high pressure fuel rail lines should only be disconnected during a camshaft or engine replacement.
If the ends of the lines are corroded as shown below, replace the fuel lines.
