1. Introduction: The PC600-6 and Its Hydraulic Pump

• The Komatsu PC600-6 is a 57-ton-class hydraulic excavator built for mining, quarrying and heavy earthmoving duty.
• The hydraulic main pump converts engine power into flow and pressure for the boom, arm, bucket, swing and travel circuits.
• When the main pump fails, the machine loses digging force and response speed - downtime in a mine is extremely costly.
• RITO HYDRAULIC supplies direct-fit PC600-6 main pumps with verified part numbers and OEM-parameter matching.

5. RITO HYDRAULIC PC600-6 Hydraulic Pump: Key Features

• OEM-Parameter Fit for PC600-6 - high pressure-flow matching with rapid machine power response.
• High-Precision Internal Components - high-pressure and wear resistance, greatly reducing internal leakage failures.
• Stable Structure & Effective Heat Dissipation - long continuous operation without easy overheating, reducing maintenance frequency.
• Available under part numbers 708-2L-00710 / 708-2L-00731 for the Komatsu PC600-6.

6. Common Hydraulic Pump Problems & Symptoms

• Weak digging force - worn pistons or valve plate reduce volumetric efficiency and output pressure.
• Slow machine response - internal leakage causes pressure-flow mismatch; the boom and arm feel sluggish.
• Abnormal noise (knocking/whining) - cavitation, worn bearings or loose couplings.
• Overheating - internal leakage generates heat; a serious issue in long mining shifts.
• Oil leaks - failed shaft or cover seals; replace with high-temperature-resistant seals.
• Sudden pressure drop - check the main relief valve setting and pump output together.

7. Maintenance & Service Tips

• Keep hydraulic oil clean (ISO 4406 cleanliness class) - contamination is the #1 cause of pump wear.
• Change hydraulic oil and filters per the Komatsu maintenance schedule; use the correct oil grade for mining duty.
• Check the suction filter and pump inlet regularly - restricted suction causes cavitation damage.
• Monitor oil temperature and system pressure; a sudden change is an early warning sign in continuous operation.
• During replacement, verify the part number (708-2L-00710 / 708-2L-00731) and coupling condition before installation.

8. Buying Guide: What to Check Before Buying

• Machine identification: exact model (PC600-6) and machine serial number.
• Old pump part number: read the plate on the failed pump and match 708-2L-00710 / 708-2L-00731.
• Quality tier: choose genuine, OEM, aftermarket or rebuilt based on machine age, duty and budget.
• Heat and duty requirements: confirm the pump is built for continuous mining operation with effective heat dissipation.
• Logistics: confirm weight and packing with the supplier to plan air vs sea freight.
• Warranty & support: confirm warranty terms, lead time and after-sales support before payment.

9. Real-World Case Study: PC600-6 Hydraulic Pump Supply (Mining Project)

RITO HYDRAULIC supplies complete PC600-6 main pumps (708-2L-00710 / 708-2L-00731) built to OEM parameters for direct installation. Key product data: high pressure-flow matching for rapid power response; high-precision, wear-resistant internals that greatly reduce internal leakage; and a stable structure with effective heat dissipation for long continuous operation in mining.

Based on our export experience, buyers replacing a failed PC600-6 pump should confirm four things before ordering: the machine model and serial number; the part number on the failed pump; the quality tier with warranty terms; and the freight plan (a mining-class main pump is a heavy, valuable shipment). With these confirmed, the correct unit ships quickly and installs without modification - keeping the excavator productive through long mining shifts.

10. FAQ - PC600-6 Hydraulic Pump

Q1: What hydraulic pump fits the Komatsu PC600-6?

The main pump for the PC600-6 is supplied under part numbers 708-2L-00710 / 708-2L-00731, with OEM-parameter fit for direct installation.

Q2: What is the PC600-6?

The Komatsu PC600-6 is a 57-ton-class mining excavator with a rated power of 287 kW @ 1,800 rpm and an engine displacement of 15.2 L.

Q3: What are the symptoms of a failing main pump?

Weak digging force, slow machine response, abnormal pump noise, overheating hydraulic oil, external oil leaks and low system pressure are the most common warning signs.

Q4: Is the RITO pump a direct fit for the PC600-6?

Yes. The pump is built to OEM parameters with high pressure-flow matching, so it installs directly with rapid power response.

Q5: Why does my main pump overheat in continuous operation?

Overheating usually comes from internal leakage or insufficient cooling. A pump with high-precision internals and effective heat dissipation, like the RITO PC600-6 unit, reduces this risk in long mining shifts.

Q6: Genuine or aftermarket - which should I choose?

Genuine parts offer the longest warranty at the highest price; quality aftermarket pumps provide verified fit at a competitive price - a practical choice for working machines. Confirm the quality tier and warranty before ordering.

Q7: How much does a PC600-6 hydraulic pump cost?

Price depends on the quality tier (genuine / OEM / aftermarket / rebuilt) and shipping. Contact RITO HYDRAULIC with your machine model and old part number for an exact quote.

Q8: How often should I service the hydraulic system?

Follow the Komatsu maintenance schedule for hydraulic oil and filter changes, and monitor oil cleanliness. Contaminated oil is the leading cause of premature pump failure.

Q9: How do I confirm the right part number?

Read the part number plate on your failed pump (e.g., 708-2L-00710 / 708-2L-00731) and check the machine model and serial number with your supplier before ordering.

Q10: Where can I buy a PC600-6 hydraulic pump?

RITO HYDRAULIC supplies PC600-6 main pumps with verified part numbers, OEM-parameter fit, warranty and export packing. Send your machine model and old part number for a quote.
