Frequently Asked Questions (FAQ)
Q1: How do I know if the hydraulic cylinder on my Hitachi EX1900-5 or EX1900-6 needs to be replaced?
A: Common signs of a failing Hitachi EX1900-5 EX1900-6 hydraulic cylinder include:
Slow or jerky movement of the attached component (boom, arm, bucket).
Loss of holding power (cylinder drifts down under load).
Visible external oil leaks around the rod seal or piston seal area.
Unusual noises coming from the cylinder during operation.
Bent or damaged cylinder rod.
Troubleshooting & Repair Tip: Check hydraulic fluid levels and condition first. Inspect the cylinder visually for external damage or leaks. If symptoms persist, internal seal failure or piston damage is likely, requiring replacement or professional repair.
Q2: Is this 4456959 hydraulic cylinder an OEM part or an aftermarket part? What is the quality difference?
A: The Hitachi 4456959 hydraulic cylinder we supply is a high-quality aftermarket replacement part. While OEM (Original Equipment Manufacturer) parts are made by Hitachi, high-quality aftermarket parts like ours are produced by specialized manufacturers who adhere to strict quality control standards, often meeting or exceeding OEM specifications.
At Swafly Machinery, we source our parts from reputable manufacturers to ensure durability, reliability, and performance comparable to the original. This allows us to offer a cost-effective solution without compromising the operational integrity of your Hitachi EX1900-5 or EX1900-6 excavator.
Q3: What maintenance is required for hydraulic cylinders?
A: Proper maintenance extends cylinder life:
Regularly inspect cylinder rods for scratches, dents, or corrosion. Keep them clean.
Check for leaks around seals and fittings. Address any leaks promptly.
Ensure hydraulic fluid is clean and at the correct level, using the manufacturer's recommended type. Contaminated fluid is a major cause of cylinder failure.
Avoid extending or retracting cylinders against their stops under full pressure unnecessarily.
Check mounting pins and bushings for wear and proper lubrication.
Maintenance Tip: A visual inspection should be part of your daily or weekly machine checks, especially for heavy-duty excavators like the Hitachi EX1900-6 operating in harsh conditions.
