How to Prevent Hydraulic System Failures
Updated: Oct 27
Hydraulic systems play a vital role in keeping Australia's transport industry moving. From tipper trucks and walking floor trailers to cranes and other hydraulic equipment, reliable performance is essential for getting the job done. However, worn components, contaminated oil and poor maintenance can lead to unexpected failures, costly downtime and interrupted operations.
The good news is that many hydraulic problems can be prevented with regular inspections and the right maintenance practices. Here's how to keep your hydraulic system working reliably.
5 Ways to Prevent Hydraulic System Failures
1. Check for Oil Leaks Regularly
Hydraulic oil leaks around hoses, fittings, pumps, cylinders and valves can indicate worn seals, loose connections or damaged components. Even a small leak can lead to reduced oil levels and poor system performance if left unchecked.
Inspect your equipment regularly and investigate leaks early. Never use your hands to search for hydraulic leaks, as high-pressure oil can penetrate the skin and cause serious injury.
2. Keep Hydraulic Oil Clean
Contaminated hydraulic oil is one of the common causes of premature component wear. Dirt, water and metal particles can damage pumps, valves and other precision components.
Follow the recommended service intervals for oil and filter changes, and use the correct oil specification for your system. Quality filtration helps protect components and extend their service life.
Clogged vanes can also affect the performance of your oil cooler
3. Monitor Operating Temperatures
Excessive heat can accelerate oil degradation and damage seals, hoses and other hydraulic components. If your system regularly runs hot, the cause could include restricted flow, excessive loading, insufficient cooling or an incorrectly sized component.
Check that oil coolers and cooling systems are working correctly, and investigate recurring overheating rather than simply continuing to operate.
4. Listen for Unusual Noises and Watch for Performance Changes
Whining pumps, unusual vibrations, slow lifting speeds and inconsistent operation can all indicate a developing problem. These symptoms may be caused by low oil levels, air entering the system, worn components or incorrect pressure settings.
Addressing changes in performance early can help prevent a minor fault from developing into a major failure.
5. Replace Worn Components Before They Fail
Pumps, power take-offs (PTOs), valves, couplings, hoses and seals all experience wear over time. Regular inspections and timely replacement of damaged or unsuitable components can help reduce the risk of unexpected breakdowns.
Always ensure replacement parts are compatible with your equipment and operating requirements.
