AG cylinders are a critical component in hydraulic systems, and their performance directly impacts efficiency and productivity. While regular maintenance can extend their lifespan, there are clear indicators that an AG cylinder should be replaced rather than repaired, including…
- Persistent Leaks
If leaks persist despite seal replacements or gasket maintenance, it may indicate a more serious issue, such as a scored barrel or rod, warped components, or a bent rod. In such cases, seal replacement may be ineffective and most likely uneconomical.
- Loss of Power or Inconsistent Operation
Reduced lifting capacity, slow movement, or inconsistent operation—especially under load (If the HPU & valves are assessed to be functional) can often point to internal wear, such as deteriorated piston seals or cylinder damage.
- Visible Structural Damage
Obvious signs of damage, such as a bent rod, deformed barrel, or corrosion can compromise the structural integrity and sealing surfaces. For an agricultural style cylinder, these defects usually necessitate replacement.
- Internal Contamination
If the hydraulic system has been contaminated by metal debris, moisture, or sludge, internal components can become damaged beyond economical repair. Scoring or erosion from contaminants is usually a sign that the cylinder requires replacement.
- Frequent Repairs or Downtime
Repeated seal failures or the need for constant servicing indicate the cylinder is nearing the end of its service life. At this point, continued maintenance becomes less economical than replacement.
- Failed Pressure Testing
Cylinders that cannot maintain rated pressure during a hydraulic test are no longer reliable. Loss of pressure retention can be a sign that replacement is required.
If any of these symptoms are observed, it may be time to assess whether a replacement AG cylinder would be more efficient than continued repair.
