Just recently converted the CAT C7 sealed fan bearing to a bearing that can be lubricated.
If interested see attached file.

CAT C7 FAN BEARING REPLACEMENT VER_1.pdf
Just got back from 800 mile trip and one mile from home the check engine came on. The engine derated and lost power.
Engine code read SPN 94, FMI 1 , fuel delivery pressure. Changed fuel filters- did not help.
Any ideas or comments, or suggestions.
