Hydraulic Cylinder FAQs
How do I know if my cylinder barrel is damaged?
Look for scoring, scratches, or internal wear during disassembly. Severe damage means you may need a replacement cylinder.
How can I tell if my hydraulic cylinder needs new seals or a full rebuild?
If the barrel and rod are in good condition, a seal kit is usually all you need. If the rod is bent or the barrel is scored, a full rebuild or replacement may be necessary.
Do you offer aftermarket cylinders or just seal kits?
We stock both seal kits and complete replacement cylinders for popular equipment brands.
How long does it take to rebuild a hydraulic cylinder?
For experienced technicians, most cylinder seal replacements take 1–2 hours. Larger cylinders or those with damage may take longer.
Why is my hydraulic cylinder drifting down?
Cylinder drift is usually caused by worn piston seals, allowing fluid to bypass internally. Installing a new seal kit fixes the issue.
Can I repair a bent hydraulic cylinder rod?
Slightly bent rods can sometimes be straightened, but most bent rods require replacement to prevent future seal damage.
Hydraulic Seal Kit FAQs
What comes in a hydraulic seal kit?
Seal kits typically include rod seals, piston seals, wear rings, wipers, and o-rings. Each kit is specific to your cylinder model.
Can I install a seal kit myself?
Yes. Many operators replace their own seals. All you need are basic tools, a seal pick, and the correct aftermarket hydraulic seal kit for your cylinder.
Can I reuse old seals if they look okay?
No. Even if seals appear undamaged, they harden and wear over time. Always install a fresh seal kit during cylinder repair.
How often should I replace hydraulic cylinder seals?
Most seals last 2–3 years under normal use. Replace them sooner if you notice leaks, drifting cylinders, or contamination.
Hydraulic Pump FAQs
Can I upgrade my pump to a higher pressure model?
It’s not recommended. Pumps are engineered to match system specifications. Using the wrong size pump may cause leaks, overheating, or damage to other components.
How long do hydraulic pumps last?
With proper maintenance, pumps can last 5,000–10,000 hours. Poor fluid maintenance shortens their lifespan dramatically.
What are the signs of a bad hydraulic pump?
Common signs include whining noises, fluid leaks, overheating, loss of pressure, and slow cycle times.
Should I rebuild or replace my hydraulic pump?
Rebuilding is cost-effective if the pump housing is in good condition. If wear is severe, replacing with an aftermarket hydraulic pump may be cheaper long-term.
Should I replace my hydraulic pump if it still works but is noisy?
Yes. Excessive noise is often the first sign of cavitation or wear. Running a failing pump can damage the rest of the system.
