What Makes a Great Hydraulic Cylinder Repair?
Insights from Goldfields Machining Experts
In the harsh environments of the Goldfields mining and construction sectors, hydraulic cylinders are under constant stress. They drive productivity—literally—and when they fail, entire operations grind to a halt.
At Goldfields Machining, we’ve rebuilt thousands of cylinders across WA and we’ve seen the difference between a quick fix and a proper repair. A great hydraulic cylinder repair isn’t just about replacing seals—it’s about restoring strength, precision, and long-term reliability.
Here’s what truly sets a professional-grade repair apart.
1. Thorough Disassembly & Diagnostic Inspection
Every great repair starts with complete disassembly and a methodical inspection of every component. Our technicians assess:
Rod straightness, chrome wear, and pitting
Barrel scoring, internal corrosion, and ovality
Piston and gland condition
Thread and port integrity
Why it matters: You can’t fix what you don’t find. A visual inspection alone won’t catch internal issues. We use precise measuring tools and proven methods to ensure nothing is missed.
2. Precision Machining & Surface Restoration
Hydraulic components must operate under extreme pressure. That’s why we rely on in-house precision machining to restore key parts like:
Re-chromed or new rods
Honed or re-tubed barrels
Machined pistons and glands
Resurfaced sealing faces and straightened tubes
Why it matters: Poor machining leads to poor sealing. We return tolerances to OEM spec—or better—and ensure your cylinder will perform in tough WA conditions.
3. Quality Seals, Rods & Materials
We only use high-quality seal kits designed for your specific machine and application. We also custom-manufacture rods and components using high-tensile, corrosion-resistant materials.
No cheap universal seal kits
No second-rate imports
No shortcuts
Why it matters: The wrong seal or a soft rod can cost you thousands in premature failure. Our repairs are made to last.
4. Clean Assembly & Pressure Testing
Cleanliness is king in hydraulic repair. Our dedicated hydraulic benches and assembly processes include:
Thorough part cleaning and contamination control
Use of correct lubricants and sealants
Professional assembly to correct torque specs
Hydraulic pressure testing to full operating load
Why it matters: Contaminants are the #1 cause of premature cylinder failure. We treat your cylinder like it’s going back into production on a million-dollar machine—because it probably is.
5. Reporting, Warranty & Full Support
A great hydraulic cylinder repair doesn’t end at the test bench. At Goldfields Machining, we provide:
Full reports on damage, measurements, and what was replaced
Before/after images (on request)
Pressure test results on request with the ability to test at 1mm intervals
Workmanship warranty
Why it matters: You deserve to know exactly what was repaired and have confidence that the work will hold up under pressure.
