Product Advantages
1. Original Genuine Parts, Precise Fit
Original CAT A28VO130 assembly with part number 531-9885 perfectly matches the 320GC/323GC; 489-3484 flange directly connects to C4.4 engine without modification.
2. Electronically Controlled Positive Displacement, Fuel-Efficient and Efficient
B o sch Rexroth technology electronically controlled twin pump adjusts flow intelligently according to load; elimination of pilot pump reduces hydraulic system energy consumption by approximately 20%, significantly improving fuel economy.
3. High Pressure and Durable, Strong Impact Resistance
Designed for 35 MPa high pressure, suitable for heavy-duty operations; high-quality alloy plungers and high-strength housing offer wear resistance, impact resistance, and aging resistance, extending service life.
4. Low Maintenance, Cost Reduction and Efficiency Improvement
No pilot pump or pilot filter, reducing maintenance items; extended hydraulic oil replacement cycle lowers comprehensive maintenance costs by approximately 20%.
Installation and Compatibility Notes
- 489-3484 is the engine connection flange; verify engine model (C4.4) and flange dimensions.
- Clean oil lines before installation, replace hydraulic oil filter to prevent impurities from wearing plungers.
- Protect electronic control connectors against water to prevent short circuit faults.
