Why won't my Gehl 603 Compact Excavator engine start?
- J
  Joan AcostaAug 21, 2025
  If your Gehl Compact Excavator's engine won't start, several factors could be at play. First, ensure you have sufficient fuel in the tank and that air is bled from the fuel system. Check the battery to ensure it has sufficient power, charging or replacing it if necessary. A contaminated fuel filter can also prevent starting, so clean it. Other potential issues include incorrect engine oil or fuel grade (replace with the proper grade), loose or corroded starter circuit connections (repair the circuit), a malfunctioning fuel injector (repair the injector), a faulty glow plug system (replace the system), incorrect engine valve clearance (adjust the valve clearance), or a malfunctioning starter/pinion (repair the starter/pinion).

  If your Gehl Compact Excavator has insufficient engine power, several factors could be responsible. Check for a fuel line leakage and replace the fuel line if needed. Ensure the engine reaches operating temperature by allowing it to warm up. Verify that you're using the correct fuel grade and replace it if it's not. Other potential causes include: contaminated air filter, incorrect engine valve clearance, oil level too high (adjust the oil level), malfunctioning fuel injector(s) (repair fuel injector(s)), or an overheated engine (check cooling system).

What to do if my Gehl Compact Excavator engine overheats?
- M
  Michael McdowellAug 25, 2025
  If your Gehl Compact Excavator engine overheats, several issues could be the cause. Ensure the coolant level is adequate by adding coolant if it is low. Check the engine oil level and add oil if it's low, or adjust if it is too high. Other potential causes: fouled oil cooler fins (clean oil cooler), damaged fan or V-belt (replace the fan / service V-belt), or malfunctioning fuel injectors (repair fuel injectors).

What does it mean when the engine oil pressure light comes on in my Gehl 603?
- A
  Anne HerringAug 26, 2025
  If the engine oil pressure indicator light comes on during operation of your Gehl Compact Excavator, stop the engine immediately. Check the engine oil level and add oil if necessary. If the oil level is correct, the oil pump may have failed and needs replacement. Also, check if the machine inclination is too high (maximum inclination is 15° up and across slopes; 25° down slopes) or if the engine oil SAE grade is incorrect (replace with proper grade).

Why is my Gehl Compact Excavator emitting smoke?
- A
  Alexander TrujilloAug 28, 2025
  If your Gehl Compact Excavator is emitting smoke, the color can indicate the problem. Blue smoke suggests adjusting the oil level. White smoke suggests replacing the fuel with the proper grade. Black smoke suggests servicing the air filter. Also, make sure that machine inclination is not too high (15° maximum inclination up and across slopes; 25° maximum inclination down slopes). If the engine starting temperature is too low, wait for the engine pre-heat cycle to complete before starting the engine. Malfunctioning fuel injectors may also be the cause and needs to be repaired.

- L
  Lindsay BrownAug 29, 2025
  If your Gehl Compact Excavator engine is running roughly, it could be due to several reasons. Incorrect fuel grade may be the cause, so replace the fuel with the proper grade. Other potential causes include: incorrect engine valve clearance, fuel line leakage (replace fuel line), or malfunctioning fuel injector(s) (repair fuel injector(s)).

What causes high engine oil consumption in my Gehl Compact Excavator?
- T
  Timothy LawsonAug 31, 2025
  High engine oil consumption in your Gehl Compact Excavator can be attributed to several factors. Ensure that the oil level is properly adjusted. The machine inclination may be too high (15° maximum inclination up and across slopes; 25° maximum inclination down slopes). Also, verify that you are using the correct engine oil SAE grade and replace it if necessary.

Why aren't the front end attachments on my Gehl Compact Excavator working properly?
- J
  Jacob HolmesSep 2, 2025
  If the front end attachments on your Gehl Compact Excavator aren't working or are performing poorly, start by checking the hydraulic fluid level and add fluid if it's low. Low engine power could also be a factor.

Why does the water temperature light come on in my Gehl 603?
- E
  Erin FordSep 4, 2025
  If the water temperature display light comes on during operation of your Gehl Compact Excavator, the coolant level may be too low, so add coolant. Another possible cause is that the fan blades are rotating too slowly. Also, the air filter may be contaminated.

Why is my Gehl 603 Compact Excavator losing hydraulic fluid?
- A
  Austin HensleySep 6, 2025
  If you're experiencing hydraulic fluid losses from the hydraulic system of your Gehl Compact Excavator, check for loose hose fittings and tighten them. Also, inspect seals, hoses, or lines for damage and replace them as needed.
