Hi, I'm hopeful some one can help me. I have a case 450 b track loader, it ran fine last time it ran. Have been told the shutoff is probably stuck, I have fuel to the pump, but none on the high pressure side. I was looking for a diagram of the injection pump so I can have an idea of where the piston is. Any help would be greatly appreciated.
make sure the linkage to the fuel pump is securely closing the shut off. Had same issue with my Case 450. Would start but very weak..due to the cable not completely closing the shut off linkage. She sounded fine when revving but had no power at all. I have to manually "help" shut it and no issues. Follow my Case 450 advice posts.
