Understand the Symptoms​
Model No.ldent No. :83006335​

Observe pump behavior. Key failure symptoms include:

1、Unusual noise/vibrations

2、Reduced performance/pressure

3、Overheating

4、Fluid leaks

5、Control system warnings

Document symptoms to guide diagnosis.

Check Fluid Levels and Quality​

KRR045DLB1828NNN3C2NGA6NKNBNNNNNN Hydraulic pumps.Verify hydraulic fluid levels. Low fluids cause cavitation and poor lubrication.
Inspect fluid for contamination (dirt, metal shavings, water). Contaminated fluid harms performance.

Inspect Hydraulic System​

Examine hoses, fittings, and connections for leaks.
Replace clogged filters to prevent flow restriction.
Check hoses for pinching/kinking that blocks flow.

Test Pressure and Flow​

Use a pressure gauge. Low pressure may indicate cavitation or dry running.
Measure flow rate with a flowmeter. Low flow signals internal wear or blockages.
