FAQ

How to prevent hydraulic pump failure?

The way to prevent hydraulic pump failure includes regular maintenance, keeping the hydraulic oil clean, regularly changing filters, and avoiding overload operation.

What are the common reasons for the hydraulic pump not working?

The reasons for not working include power supply problems, low hydraulic oil level, filter blockage, hydraulic line leakage and pump internal component failure.

How do you troubleshoot abnormal exhaust smoke from an excavator engine?

Abnormal exhaust smoke can indicate various engine issues:

 

1. Black smoke: 

Check for clogged air filters, over-fueling, or issues with the fuel injectors. Inspect the turbocharger (if equipped) for damage.

 

2. Blue smoke: 

Indicates oil burning. Check for worn piston rings, valve seals, or a damaged turbocharger.

 

3. White smoke: 

Can be caused by coolant entering the combustion chamber. Inspect the cylinder head gasket, cylinder head, and cooling system for leaks. Additionally, ensure the fuel injectors are operating correctly and not causing unburned fuel to emit as white smoke.

What are the common symptoms of hydraulic pump wear?

Symptoms of wear include reduced efficiency, increased noise, leakage, and reduced hydraulic function.
