Why Are Hydraulic Repairs Important?
There are numerous reasons why hydraulic repairs on equipment and machinery are crucial.
- Injury Prevention: Hydraulic systems operate under high levels of pressure, and a breakdown of the internal components can cause that pressure to accumulate and blow out with velocity that can cause damage to property, physical injury or potentially a fatality
- Environmental Protection: Worn-down or split seals can cause potentially harmful fluid to leak out
- Downtime Prevention: Ensuring that your machinery is repaired by experts quickly will lower the amount of time your workload is impacted after the breakdown, and moving forward
- Efficiency: High-quality hydraulic repairs will make your equipment operate at its peak level for longer, improving efficiency
Our Services

Hydraulic Motor Repair
Need fast hydraulic motor repairs? CJ Plant offers expert servicing and repairs, including swing motor reconditioning, to keep your equipment running smoothly and minimise any downtime. We can cater for all repair types, right from a basic reseal, through to fully reconditioning your unit replacing all damaged and worn parts.
Control Valve Repair
Control valve repairs are crucial to ensuring your hydraulic systems are working as intended. Whether your unit is leaking or as a service not working due to a “sticky spool”, the qualified engineers at CJ Plant can repair it back to industry standard.
Swivel Joint Repair
Although a swivel joint is one of the most long-lasting units out there, being able to last for years on end in the most abrasive conditions, it will eventually break down. To avoid costly replacements, let the team at CJ Plant diagnose the problem and use our collective experience to repair and rebuild.
Final Drive Repairs
The final drive is what transfers movement and power from your equipment to wherever it needs to go. If it is in poor condition, the manoeuvrability, efficiency and load capacity can all be affected. Whether it is a leaking seal, a worn-out bearing or broken gears and shafts, finding and fixing this problem is crucial to preventing unwanted downtime.
