Troubleshooting Test Steps | Values | Results |
---|---|---|
1. Check for Damaged or Plugged Air Filter Elements |
Air Filter Element |
Result: The air filter element is not plugged and the piping is not restricted. Proceed to Test Step 2. Result: The air filter element is plugged or the piping is restricted. Repair: Clean or replace the air filter element. If the problem is not resolved, proceed to Test Step 2. |
2. Inspect the Enclosure A. Check that the engine has been installed in an enclosure that is sufficiently ventilated. |
Enclosure |
Result: The engine enclosure is not sufficiently ventilated. Repair: Repair the ventilation for the enclosure. Verify that the repair eliminated the problem. |
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
