Case 1845C Not Staying Running
#1
The Case 1845C skid steer loader has been reported by several users to experience a problem where it won't stay running after startup. The machine may start briefly and then shut down, causing a halt in operation. The root cause of this issue could be related to multiple factors, including the fuel system, electrical components, battery, and more.
Common Causes of the Problem
  1. Fuel System Issues
    Fuel system problems are among the most common causes of the engine cutting out after starting. The issue may lie with the fuel filter, fuel pump, or clogged fuel lines. When the engine doesn't get enough fuel, it can shut down. Check the fuel filter and pump for blockages or wear, and ensure the fuel lines are clear.
  2. Electrical Issues
    Many times, electrical system failures can prevent the engine from staying running. Inspect the battery, starter circuit, and electrical connections to ensure there is no voltage instability or loose connections. An old or weak battery, as well as poor connections, could be the source of the issue.
  3. Air Filter Issues
    A clogged air filter can limit airflow to the engine, resulting in poor combustion and leading to shutdowns. Check and clean or replace the air filter to ensure the engine is receiving sufficient air for proper operation.
  4. Engine Overheating
    If the engine overheats, it may shut down automatically to prevent damage. This can occur if the coolant level is low or if there is a failure in the cooling system. Check the coolant level and the cooling system's performance to ensure the engine is adequately cooled.
  5. Sensor or Electronic Component Failures
    Modern machinery relies on sensors to monitor engine functions and other critical systems. A malfunction in any of these sensors or electronic components can cause the engine to shut down incorrectly. Inspect all sensors and electronic components, especially temperature and pressure sensors, to make sure they are working properly.
Suggested Solutions
  1. Inspect the Fuel System
    Replace or clean the fuel filter and ensure the fuel pump is operating correctly. Look for blockages or leaks in the fuel lines.
  2. Check the Battery and Electrical System
    Verify that the battery is fully charged and in good condition. If there are loose or corroded electrical connections, clean and secure them.
  3. Clean or Replace the Air Filter
    Regularly inspect the air filter for dirt and debris. If it’s clogged, clean or replace it to allow for optimal engine airflow.
  4. Examine the Cooling System
    Make sure the coolant level is sufficient and the cooling system is functioning properly. Clean the radiator if necessary, and check for leaks in the cooling system.
  5. Diagnose the Electronic System
    If the problem persists, use a diagnostic tool to check the electronic control system for any sensor malfunctions. Identifying faulty components can help pinpoint the issue.
Conclusion
The issue of the Case 1845C skid steer loader not staying running can stem from a variety of sources, including problems with the fuel system, electrical system, air filter, or engine overheating. By systematically checking each system and performing necessary maintenance, operators can effectively resolve the issue and return the machine to normal operation.
