⚠️ Safety Warning

Before replacing the pump, you must completely depressurize the hydraulic system by lowering all attachments to the ground and operating all levers with the engine off. Hot hydraulic oil can cause severe burns.

Part's Role in the Machine and Failure Diagnostics

The hydraulic pump is the key component that generates the machine's power. Its wear leads to a drop in pressure, which manifests as a lack of force, slow operation, and overheating of the oil. A pump failure immobilizes the entire machine.

  • › Lack of power on all hydraulic functions.
  • › Very slow operation of the entire hydraulic system, especially on warm oil.
  • › Loud, "whining" pump operation, indicating cavitation or seizure.
  • › Overheating of the hydraulic oil.
  • › Presence of a large amount of metal filings in the hydraulic oil and filter.

Peace of Mind Guarantee: Why Choose Our Offer?

A worn pump means an immobilized machine and costly downtime.

Shrapnel from a worn pump contaminates the entire system, destroying valves and rams. The cost of a new pump is negligible compared to a full hydraulic system overhaul. Don't take the risk – order a new, reliable PARKER pump and restore your machine's full power and efficiency.

🔧 Expert's Guide: Key Installation Tips

  1. Flush the system: Before installing a new pump, thoroughly flush the entire hydraulic system, especially the tank, to remove old metal filings.
  2. Replace oil and filters: Always install a new pump with new hydraulic oil and new filters. Old, contaminated oil will immediately damage the new pump.
  3. Prime the pump with oil: Before the first start-up, prime the pump with clean hydraulic oil to avoid a dry start and seizure.
  4. Check the drive shaft: Inspect the condition of the spline and U-joints on the pump's drive shaft.

Frequently Asked Questions (FAQ)

1. Why does this pump have two sections?

This is a tandem pump. In simple terms, one section with a higher displacement supplies the main working functions (e.g., the backhoe arm), while the smaller section can supply, for example, the power steering system or other auxiliary circuits. This allows for independent and stable operation of all systems.

2. How do I check if the pump is worn out?

The best method is to measure the pressure and oil flow using specialized equipment (a pressure gauge and flow meter), according to the service manual. Significantly lower parameters than nominal values indicate pump wear.

3. I found metal filings in the hydraulic filter. What does that mean?

Metal filings in the filter are a sign of a serious mechanical failure within the system. They most often come from a disintegrating hydraulic pump. In this case, you should stop work immediately and perform an overhaul to avoid contaminating and destroying the entire system.
