FAQ
How to troubleshoot the excavator's swing system?
Swing system issues are usually related to the hydraulic motor, swing gears, or control valves. First, check the operation of the hydraulic motor, inspect the gears for wear, and ensure the control valves are working properly. Replace faulty parts as needed.
Why can't the crankshaft rotate when the excavator starts?
- The starter and flywheel teeth are not meshed well. The ring gear and the starter gear collide when starting the engine, causing tooth damage or single-sided wear of the teeth. If more than three teeth are damaged or worn seriously, it will be difficult for the starter gear and the ring gear to mesh.
2. Cylinder sticking. When the engine temperature is too high, the engine is stopped and the heat is difficult to dissipate. The piston ring at high temperature sticks to the cylinder and cannot start after cooling.
3. Crankshaft lock. Due to lubrication system failure or lack of oil, the sliding bearing rubs dry, which eventually locks the crankshaft and cannot start.
4. The injection pump plunger is stuck.
If i don'thave part number, can you check for me?
Yes, excavator model, old photos, and size are also available to confirm the correct parts you need.
Why should I check and replace the fuel filter?
Regularly checking and replacing the fuel filter can prevent impurities from entering the fuel system, ensure fuel cleanliness and extend the life of the engine.
