Troubleshooting Smoking Issue with 2003 CAT 740 Truck: Starter and Solenoid Replaced, But Problem Persists - Seeking Advice

Question:

In 2003, my 740 Caterpillar started smoking when I tried to start it. I replaced the starter and starter solenoid, but the issue persists. It's not the neutral switch, dump lever, or parking brake. Any suggestions on what might be causing this issue would be greatly appreciated by someone who has dealt with a similar problem before. Thank you.

Before starting the engine, make sure to attach a turning tool and rotate it at least twice to confirm that the crankshaft moves smoothly. This step is crucial for ensuring proper engine operation and preventing potential issues.

No, I haven't, but that is actually a good idea. It is possible that could be the reason for the issue. I will definitely look into that. Thank you for suggesting it.
