Hydraulic systems power everything from heavy equipment in mining and agriculture to industrial machinery and offshore rigs. When components like pumps, motors, valves, or cylinders fail, productivity takes a direct hit. Whether you’re searching for hydraulic repair near me, or want expert hydraulic repair services that get your equipment back in action fast, understanding the most common failures is the first step to prevention—and recovery.
At Gerrard Hydraulics, we’ve been servicing Western Australia’s hydraulic industry since 1978. From hydraulic cylinder repairs to full hydraulic equipment repair services, we cover a wide range of components and offer a full spectrum of diagnostics, testing, repairs, and remanufacturing from our Perth workshop.
Key Hydraulic Components and Parts That Often Need Repair
The most frequently serviced hydraulic parts include:
- Hydraulic cylinders
- Fixed and variable gear pumps and motors
- Fixed and variable piston pumps and motors
- Gerotor and geroller motors
- Directional control valves
- Pressure control valves
- Flow control valves
- Hydraulic accumulators
- Planetary gearboxes
- Hydraulic transmissions
These components often fail due to predictable issues like contamination, seal leaks, overpressure, and wear and tear—especially in Australia’s harsh working environments.
Most Common Hydraulic Repair Issues
1. Fluid Contamination
Contaminants such as water, dirt, or metal particles are the leading cause of hydraulic component failure. Once inside, they damage seals, score cylinder bores, block ports, and reduce system efficiency.
Causes:
- Improper fluid handling
- Cylinder rod ingress
- Poor filtration systems
Prevention: Regular oil analysis, proper filtration, and fluid replacement help minimise contamination.
2. Hydraulic Leaks
Leaks in hydraulic systems are usually caused by worn seals, damaged hoses, or faulty fittings. Even small leaks reduce pressure and lead to system inefficiencies and unsafe operating conditions.
Common leak points:
- Valve spools
- Pump housings
- Cylinder rods
- Hose connections
Warning Signs:
- Visible oil around joints
- Gradual pressure loss
- Equipment performing below capacity
3. Overheating
Hydraulic fluid should ideally operate between 35°C and 60°C. Anything above that can reduce viscosity, damage seals, and shorten component life.
Causes:
- Inadequate cooling systems
- Overloaded machinery
- Dirty filters
- Incorrect fluid grades
Solutions: Upgrade coolers, use high-quality hydraulic oils, and inspect system load performance.
4. Pump & Motor Failure
Hydraulic pumps and motors are at the heart of most hydraulic systems. When they fail, the entire operation stalls.
Pump Failures:
- Worn vanes, pistons, or gears
- Damaged bearings
- Pressure imbalances
- Air or water in the fluid
Motor Failures:
- Seal degradation
- Rotor scoring
- Internal leakage
Prompt hydraulic repair services can recondition these units, avoiding expensive replacements.
5. Valve Malfunctions
Hydraulic valves are responsible for directing flow, managing pressure, and regulating speed. Contamination, wear, or misalignment can cause them to stick, leak, or fail entirely.
Symptoms of Valve Failure:
- Jerky movements
- Unexpected pressure drops
- Slow response
- Excessive noise
