Updated: 2 October 2026
Hydraulic cylinders are used across construction plant, transport equipment, waste handling machinery, lifting equipment and industrial systems. When a cylinder starts leaking, drifting, losing force or moving incorrectly, identifying the underlying fault is important before deciding whether it needs resealing, rebuilding or replacement.
Our mobile hydraulic engineers can attend suitable breakdowns around Upminster, while cylinders requiring substantial dismantling, measurement, machining or rebuilding can be handled through our workshop operation.

Hydraulic Services for Upminster Businesses & Machinery
Upminster and the surrounding East London area include transport, construction, commercial and industrial operations where hydraulic equipment is essential to everyday work.
Our hydraulic engineering support can include:
- Hydraulic cylinder and ram assessment
- Cylinder resealing where appropriate
- Hydraulic cylinder rebuilding
- Rod, bore, gland and piston assessment
- Mobile hydraulic hose replacement
- Hydraulic fault diagnosis
- Valve and component investigation
- Hydraulic system repair support
- Replacement and custom cylinder requirements
The appropriate repair depends on the condition of the equipment and the actual cause of the fault rather than assuming every cylinder problem requires the same solution.
Common Hydraulic Cylinder Problems
| Symptom | Possible Areas to Investigate |
|---|---|
| External oil leak | Seals, rod surface, gland, fittings, connections or physical damage |
| Cylinder drifting | Internal cylinder leakage, control valve leakage or another circuit fault |
| Reduced force | Internal leakage, system pressure, pump performance, valves or cylinder condition |
| Jerky or uneven movement | Air, contamination, alignment, cylinder condition, flow or control issues |
| Damaged piston rod | Scoring, corrosion, bending, impact damage or surface deterioration |
| Repeated seal failure | Rod or bore damage, contamination, side loading, misalignment, pressure or operating conditions |
These symptoms provide useful diagnostic clues, but they do not automatically identify which hydraulic component has failed.
Does a Leaking Hydraulic Ram Just Need New Seals?
Sometimes resealing is the correct repair, but a leak does not automatically mean the seals are the only problem.
Rod scoring, gland wear, bore damage, contamination, side loading or poor alignment can damage seals and cause repeat leakage. Inspecting the cylinder helps determine whether resealing alone is appropriate or whether further repair is needed.
What Happens During a Hydraulic Cylinder Rebuild?
The exact repair process depends on cylinder design, condition and application. A workshop rebuild may involve:
- Initial assessment — understand the reported fault and application.
- Dismantling — strip the cylinder where appropriate.
- Inspection — assess the rod, bore, gland, piston, seals and associated components.
- Measurement — determine relevant wear and damage.
- Repair or machining — where technically appropriate.
- Seal replacement — install suitable sealing components.
- Reassembly — rebuild the cylinder using appropriate workshop procedures.
- Testing — carry out checks suitable for the cylinder, repair and intended application.
Not every cylinder requires honing, machining or an identical testing procedure. The work should be determined by what is found during inspection.
Mobile Hydraulic Support vs Workshop Cylinder Repair
Mobile Engineer in Upminster
Mobile engineers can assist with suitable hydraulic breakdown diagnosis, hose replacement and external inspection, including determining whether an apparent cylinder problem could originate elsewhere in the hydraulic system.
Workshop Cylinder Repair
Workshop conditions are more suitable for substantial dismantling, accurate measurement, machining, honing where appropriate, rod work, rebuilding and controlled testing.
A mobile engineer can diagnose many problems at the machine, but that does not mean every hydraulic cylinder should be dismantled or rebuilt on site.
Can a Damaged Hydraulic Cylinder Rod Be Repaired?
Possibly. The correct approach depends on the type and extent of the damage.
Common piston rod problems include:
- Scoring
- Pitting
- Corrosion
- Bending
- Impact damage
- Surface deterioration
Rod dimensions, material, surface condition, straightness, cylinder design and application all need to be considered.
If the rod is badly damaged, simply replacing the seals may result in another leak. Repair or rod replacement may be required depending on the condition found.
Should You Repair or Replace a Hydraulic Cylinder?
Many hydraulic cylinders can be rebuilt, particularly where a direct replacement is expensive, obsolete or difficult to obtain. Repair is not automatically the right option in every case, however.
The decision can depend on:
- Overall cylinder condition
- Rod and bore damage
- Repairability
- Replacement availability
- Parts availability
- Machining requirements
- Machine downtime
- Repair and replacement cost
- Equipment criticality
- Application and safety requirements

Replacement & Custom Hydraulic Cylinders
If an existing cylinder is obsolete, unavailable or beyond economical repair, manufacturing a replacement may be an option.
A replacement cylinder needs to be specified for the machinery and its operating requirements. Relevant factors can include:
- Bore
- Rod diameter
- Stroke
- Mountings
- Ports and connections
- Operating pressure
- Required force
- Operating speed
- Duty cycle
- Materials
- Operating environment
- Machine geometry
Correct Specification Comes First
A replacement cylinder should be correctly engineered for the hydraulic system, machinery, load and operating environment. Describing a cylinder as “better than OEM” is not a substitute for correctly matching it to the application.
Mobile Hydraulic Hose Replacement in Upminster
Completely Hydraulic also provides suitable mobile hydraulic hose replacement around Upminster, Hornchurch and surrounding East London areas.
A damaged pressure hose should normally be replaced with a complete suitable hose assembly rather than patched for continued normal operation.
Correct hose replacement requires consideration of:
- Nominal hose size
- Working pressure
- Hydraulic fluid
- Temperature
- Fittings and connection type
- Routing
- Minimum bend radius
- Machine movement
- Abrasion and environmental exposure
See our Hydraulic Hose Solutions.
High-Pressure Hydraulic Safety
Never use a hand or finger to search for a hydraulic leak. Pressurised hydraulic fluid can penetrate the skin and cause a serious injection injury. Machinery should be safely isolated and stored hydraulic energy controlled before appropriate inspection.
What if the Hydraulic Cylinder Is Not Actually the Problem?
A machine that moves slowly, cannot lift correctly or fails to hold position may appear to have a cylinder fault, but other hydraulic and mechanical problems can produce similar symptoms.
Diagnosis may need to consider:
- Hydraulic pump performance
- Directional valves
- Pressure-control valves
- Internal valve leakage
- System pressure
- Restricted flow
- Hydraulic oil condition or viscosity
- Contamination
- Hoses and fittings
- Mechanical loading
Diagnosing the system before replacing components can help prevent unnecessary repairs and repeat failures.

Can you reseal a hydraulic ram in Upminster?
Hydraulic cylinders can be resealed where inspection shows that resealing is appropriate. Additional repair may be required if rod, bore, gland or other component damage is present.
Can you rebuild hydraulic cylinders on site?
Some diagnosis and suitable hydraulic work can be carried out on site, but substantial dismantling, machining and rebuilding are generally better suited to a controlled workshop environment.
Why does my hydraulic cylinder keep leaking?
Repeated leakage can be associated with seal wear, rod damage, contamination, bore or gland condition, misalignment, side loading, pressure or operating conditions.
Why is my hydraulic cylinder drifting?
Internal cylinder leakage can cause drift, but control valve leakage and other circuit faults can produce similar symptoms. Diagnosis should establish the cause before unnecessary cylinder work is carried out.
Can a damaged hydraulic cylinder rod be repaired?
It may be possible depending on the extent and type of damage, rod dimensions, material, surface condition and application.
