Procurement Guide: 708-3S-00513 Replacement Performance Comparison

Understanding the difference between a high-quality aftermarket pump and a low-grade alternative is vital for long-term operational cost reduction.

Core Procurement Factor	Our OEM Standard Replacement	Common Low-Grade Alternatives
1. Core Material Quality	High-strength alloy steel with anti-wear treatment	Standard recycled cast iron
2. Internal Sealing Unit	Premium high-pressure resistant seals	Low-temperature vulnerable rubber
3. Pressure Tolerance	Exceeds 250 bar (Matching PC35MR-2 Specs)	Unstable performance above 200 bar
4. Flow Consistency	Variable displacement precision matching	Erratic flow leading to jerky movements
5. Noise Level	Optimized internal structure for quiet operation	Heavy cavitation noise during load
6. Lifetime Expectancy	Designed for over 5,000 working hours	Short lifespan (often failing within 1,200 hrs)

Technical FAQ & Troubleshooting for PC35MR-2 Hydraulic Issues

Q1: Why is my PC35MR-2 excavator losing power when the hydraulic oil gets hot?

A: This is often caused by internal leakage within the 708-3S-00513 pump. When the oil thins out due to heat, worn internal surfaces allow oil to bypass the pressure chambers. Replacing the pump with a new unit restores the volumetric efficiency needed for heavy digging.

Q2: My excavator makes a high-pitched whining noise from the main pump area. Is it the 708-3S-00513?

A: High-pitched whining usually indicates cavitation or air ingestion. Check your suction lines first. If the noise persists and the 7083S00513 casing is vibrating excessively, the internal bearings or piston shoes may be failing. Immediate replacement is recommended to prevent metal debris from contaminating the entire hydraulic circuit.

Q3: Why Choose This Hydraulic Pump?

A: Our 708-3S-00513 features an OEM-standard tri-metal structure and high-precision finishing on the swash plate and cylinder block. It is trusted by repair shops and equipment fleets globally for its reliability under harsh construction conditions.
