Preventative Maintenance Tips for Hydraulic Systems
It’s Monday morning and you don’t want to get out of bed and your machine won’t cooperate. A leaky hydraulic line, humming pump or slow operation has brought your workflow to a standstill.
Ugh! If you’ve been there you know what it’s like to be out of commission — your time, your money, your work. But don’t worry! With a little TLC you can keep your hydraulics smoother than a butter slide.
Hydraulics aren’t just hoses, pumps and fluid; they’re the heartbeat of everything from buildings to agriculture. Preventative maintenance is the way to go if you’re running heavy machinery, factories or just want to make sure your machinery runs at peak performance. Not sure where to start? So don’t worry, I’ve got a few simple, actionable tips to keep you and your hydraulics out of the repair shop.
1. Check Fluid Levels
Hydraulics operate on fluid just like cars operate on fuel. Too little or not enough? Boom—problems. Check fluid levels at least once a week or during periods of heavy use. Think of it as watering your body—dehydration means slow reaction (and maybe more).
Tip: Always use the manufacturer’s recommended hydraulic fluid. Mixing and matching with low quality is a recipe for disaster.
Oh and while you’re at it, check for rusty spots or musty smells. These are contamination alerts.
2. Invest in Quality Repairs
Let’s face it: even the best maintenance fails. When they do, don’t compromise. Patch jobs can save you a buck today and thousands tomorrow.

3. Keep it Clean
Ever wondered what happens when dirt, grime or water gets into your hydraulic system? Spoiler alert: nothing good. Contaminants are tiny little saboteurs – they’ll destroy seals, valves and pumps fast.
Quick Fix: Inspect hoses, connectors and reservoirs. Remove dirt and lubricate fill ports before filling with oil. Prevention is key and easier than cleaning up a hydraulic leak.
4. Check Hoses and Connectors for Leaks
Leaks are sneaky little devils — they can start small and end up big. So if you see oil spots under your gear or water stains around your hoses, don’t just brush it off.
Prevent leaks before they cause downtime and environmental disasters. Cracks, bulges or worn out fittings? Replace them now. And remember, snug is not the same as squeezing! That can do more harm than good.
5. Check Pressure Settings
Hydraulics are all about harmony. To push them past their optimal pressure is like pressing the gas and brake at the same time — don’t do it. Overpressurization can damage seals and other parts and underpressurization reduces performance.
Have gauges handy to keep pressure in the sweet spot and watch out for pulses which may indicate a bigger problem.
6. Don’t Ignore the Filters
Filters are your hydraulic machine’s BFF. They collect dust, dirt and contaminants that might otherwise block the machine. But filters don’t last forever. To leave them out is like not changing your car’s air filter – it gets clogged and performance dips.
Replace filters at regular intervals or when they get clogged. The longer you run your hydraulics the less headaches they will give you.
7. Keep it Cool
Hydraulic systems don’t like heat. Too much heat degrades the fluid, destroys seals and makes everything brittle. So keep an eye on the temperature and make sure cooling elements like fans or heat exchangers are operating.
If it starts to get hot, you need to investigate. Clear blocked radiators, check fluid levels and inspect hoses for blockages.
8. Don’t Skip Maintenance
The fact is: computers are like us. They need regular tune-ups. When you maintain your home you prevent small problems from becoming big ones.
Schedule a maintenance time and stick to it. Whether you’re checking seals, replacing parts or evaluating system performance, a little work upfront pays off in the long run.
9. Listen and Observe
Yes, your hydraulic system talks. Phony noises, jerks or slow startup? These are SOS signals that something’s not right. A hum of a pump or rattle of a valve is more than annoying – it’s an outrage.
Consider your system’s behavior. Find out what’s normal so you can tell when something’s not.
10. Train Your Team
You can only do as much with your hydraulics as the people who operate them. If your crew doesn’t know what they’re doing you’re in trouble.
Have everyone learn how to use, troubleshoot and do maintenance. If you know how to treat the system right you’ll get fewer outages and better performance.
11. Watch for Piston and Cylinder Wear.
Hydraulic pistons and cylinders take the brunt of your machine so they wear out. The problem? When they wear unevenly it creates holes, makes them less efficient and can even leak fluid.
Check cylinders for scratches, dents or vibration. The next time something feels weird (like a stutter or loss of power) maybe you need to investigate. You can avoid wasting time by replacing old pistons and cylinders before they totally blow.
Tips: Lubricate pistons with the right hydraulic fluid to reduce friction and extend their life.
12. Watch Seals and Gaskets: Seals and gaskets.
Seals and gaskets are small but they’re crucial to seal leaks and keep your hydraulic system at the right pressure. Over time they harden, crack or break especially when exposed to too much heat, pressure or contaminated fluid.
Check seals and gaskets during maintenance. Look for tears, rips or deposits of residue. A broken seal is a pain in the butt but believe me it’s much easier (and cheaper) than a big fluid leak.
Tips: Keep spare seals dry and fresh, keep them dry in case of an emergency.
In a Nutshell
Preventative maintenance isn’t the most fun job but it’s the most important. You brush your teeth, change your car’s oil etc, you know — it’s a small amount of time and money that adds up over time.
Keep your hydraulic systems clean, lubricated and inspected to save on repair costs, downtime and maintenance costs and extend the life of your equipment. And you’ll save yourself a whole lot of grief.
So, put on your gloves, grab a torch and maybe some coffee and get to loving your hydraulics. And yes, even when you’re at your wit’s end there’s CJ Plant’s Hydraulic Repair Services by your side. They’ll look after you and let you get on with the job.
