Signs your hydraulics need attention
| What you notice | Likely causes |
|---|---|
| Wet hoses or oil under the machine | Leaking hose, fitting or seal |
| Slow or weak functions | Low or hot oil, blocked filter, worn pump, relief valve setting |
| Whining or knocking | Air in the system, low oil, restricted suction, pump wear |
| Cylinder drifts down | Internal seal leak or a valve problem |
| Oil running hot | Blocked cooler, low oil, internal leakage, wrong oil |
Heat, dust and hydraulics
Pilbara heat is hard on hydraulic systems. Hot oil thins, seals harden faster, and dust packed into the oil cooler makes it worse. Contamination is the other big killer: dust through a damaged breather or an open filler cap wears pumps and valves from the inside. When we fix a leak, we also check the cooler, breather, filters and oil condition so the same fault doesn’t come straight back.
Burst hose? Do this first
- Stop the machine and lower any raised attachment to the ground.
- Never feel for a leak with your hand. High-pressure oil can inject through skin, which needs urgent medical help.
- Contain spilled oil if you can.
- Note which function failed, take a photo of the hose and its tag, and call 0407 497 068.
What to have ready when you call
- The machine: make, model and rough size (for example a 20 tonne excavator or a wheel loader).
- Hour meter reading, if you can see it.
- What happened: what it was doing when it failed, any noises, smoke, leaks or warning lights.
- Any fault codes on the screen. A photo of the display on your phone is perfect.
- Where it is: the address or site, and how to get to the machine.
- Site rules: any induction, PPE, permits or escort needed before we can start work.

Frequently asked questions
Can you replace a burst hydraulic hose on site?
Yes. Tell us the machine and send a photo of the hose and its fittings when you call so we bring the right parts.
Why are my hydraulics slow when the machine is hot?
Hot oil thins and internal leakage rises. Check the cooler isn’t packed with dust and the oil level is right, then call us to test the system.
Is a small hydraulic leak urgent?
It will only get worse, and leaks let dirt in. Get it looked at before it becomes a burst hose and a machine off the job.
Do you repair hydraulic cylinders?
We diagnose cylinder leaks and drift on site and arrange the repair, whether that’s seals on site or a rebuild.
