How to troubleshoot starting problems with CASE CONSTRUCTION Excavators when the starter doesn't rotate?
- A
  Adam MartinezAug 7, 2025
  If the engine of your CASE CONSTRUCTION Excavator doesn't start and the starter motor either doesn't rotate or rotates weakly, several factors could be at play. It might be due to a discharged battery, in which case you should charge or replace it. Check for disconnection, looseness, or corrosion at the battery terminals; repair any corroded areas and ensure they are securely tightened. Also, inspect the starter ground wire terminal for detachment, looseness, or corrosion, addressing it similarly. High engine oil viscosity can also hinder starting, so replace it with oil of appropriate viscosity. If these steps don't resolve the issue, the starter or electrical system may be faulty, and you should consult your CASE CONSTRUCTION Dealer.

Why does my CASE CONSTRUCTION Excavator engine start then immediately stop?

  If the engine of your CASE CONSTRUCTION Excavator starts but stops immediately, it could be due to a few common issues. Check for a clogged fuel filter; if it's clogged, remove moisture and replace the element. Similarly, a clogged pre-fuel filter can cause this problem, so clean or replace that element as well. Also, ensure the air cleaner isn't clogged by cleaning or replacing its element. If the supply pump strainer is clogged, you should clean the strainer. For failures of the engine control system or the supply pump, consult your CASE CONSTRUCTION Dealer.

  If the engine revolution of your CASE CONSTRUCTION Excavator is unstable, it could be due to a failure in the fuel system, in which case you should consult your CASE CONSTRUCTION Dealer. Alternatively, there might be water or air intrusion in the fuel system, requiring you to remove the air. If there is a failure of the engine control system, consult your CASE CONSTRUCTION Dealer.

Why is the exhaust smoke white on my CASE CONSTRUCTION Excavator?
- M
  Michael GreerAug 31, 2025
  If the exhaust smoke from your CASE CONSTRUCTION Excavator is white, there are several possible causes. It could be due to insufficient warming-up, so perform warming-up. Another reason may be too much engine oil, so adjust to the appropriate oil amount. If you have been continuously idling for a long period (more than two hours), raise the engine speed and confirm that white smoke is not emitted. For a failure of the engine control system, failure of the supply pump, or failure of the fuel system, consult your CASE CONSTRUCTION Dealer.

What to do if CASE CONSTRUCTION Excavator engine won't start but the starter turns over?

  Susan AvilaNov 12, 2025
  If your CASE CONSTRUCTION Excavator's engine isn't starting but the starter turns over, it could be due to several reasons. First, check if there's fuel in the fuel tank, ensuring there is no fuel leakage and refueling if necessary. Air intrusion in the fuel system could also be the culprit; in this case, you should remove the air. Another potential issue is a clogged fuel filter, which requires removing moisture and replacing the element. In cold conditions, the fuel may be frozen, so try warming up the fuel pipe with hot water or waiting for the air temperature to rise. Also, check the strainer of the supply pump and clean it if it’s clogged. If the overflow valve remains open, clean or replace the supply pump, fuel filter or fuel port overflow valve. For failures of the supply pump or e...
