  If you're having trouble starting your Kubota Engine, several factors could be at play. Insufficient compression due to leaking valves or worn rings, pistons, and liners may be the cause; consider replacing these parts or grinding the valves. A dirty air cleaner, which should be cleaned every 100 hours, can also be the culprit. Ensure the fuel injection pressure is correct and that you're using No. 2-D diesel fuel to prevent injection pump wear. Also, verify that the valve clearance is properly adjusted when the engine is cold. Overheating of moving parts may also make it difficult to start the engine, in this case, check the lubricating oil system and injection timing.

  If your Kubota Engine is overheating, several issues could be responsible. Insufficient engine oil or coolant levels should be checked and replenished as needed. A broken or elongated fan belt requires adjustment or replacement. The radiator net or fins might be clogged with dust, necessitating careful cleaning. Also, ensure you are using the specified fuel and not running an overload. Other potential causes include excessive antifreeze concentration (correct by adding water), a defective thermostat (check and replace if needed), or incorrect injection timing (adjust to the proper timing).

  If your Kubota Engine suddenly stops, the problem could stem from a lack of fuel; check the fuel tank and system for leaks or air. A bad nozzle may also be the cause, and it should be replaced if necessary. Shortage of lubrication oil or improper lubrication may lead to the moving parts overheating, so check the oil level and lubricating system.
