Your excavator is down. A haul truck has a leaking ram. A critical piece of agricultural machinery is sitting idle in the shed. When a vital piece of heavy equipment stops working in Western Australia, every single hour of downtime costs you money. Your first question is always the same: “How much is this going to cost to fix, and how fast?”
Trying to find a single, fixed price for a hydraulic cylinder repair is like asking for the price of a house—it depends entirely on the size, location, and condition. While giving a precise figure without seeing the cylinder is impossible, this guide will do the next best thing.
This guide will break down the key factors that determine the final cost of a hydraulic cylinder repair in Western Australia. Our goal is to help you better understand the quotes you receive, recognise the value of a quality repair, and make an informed decision to get your operation back up and running.
A Quick Guide: Average Cylinder Repair Costs
Before we dive into the details, let’s address the main question. To give you a ballpark idea, we’ve outlined some common repair scenarios.
- Simple Reseal (Small Cylinder): For a small, straightforward cylinder like one from a bobcat or a small tractor, a standard reseal is the most common job. This typically ranges from $400 to $900.
- Reseal & Minor Polish (Medium Cylinder): For a medium-sized cylinder, such as an excavator bucket ram, that requires new seals and a light polish of the rod, you might expect costs in the range of $1,200 to $2,500.
- Full Rebuild (Large/Complex Cylinder): This is for a large, heavy-duty cylinder from a mining haul truck or a large dozer. A full rebuild can involve re-chroming the rod, honing the barrel, and manufacturing new components. These complex jobs can range from $5,000 to $15,000+, depending on the extent of the damage.
Crucial Disclaimer: These prices are illustrative examples only. The final cost of your repair will depend on a combination of factors, which we will now explore in detail.
The 4 Key Factors That Determine Your Final Repair Bill
Understanding what goes into a quote is the best way to appreciate the value of a professional repair. The price is never arbitrary; it’s a direct reflection of the work, skill, and materials required.
Factor 1: The Cylinder’s Size and Complexity
This is the most significant cost factor. A small hydraulic cylinder can be lifted onto a workbench by a single technician. In contrast, a massive hoist cylinder from a Pilbara haul truck can be several metres long, weigh over a tonne, and require overhead cranes and specialised large-scale machinery just to handle and disassemble it.
The sheer scale impacts every aspect of the repair. A larger cylinder requires more man-hours, a larger volume of expensive hydraulic fluid, a bigger and more costly seal kit, and more time for testing. A multi-stage telescopic cylinder, like those on tipper trucks, is also far more complex and time-consuming to disassemble and rebuild than a simple, single-rod cylinder.
Factor 2: The Type and Extent of Damage
The nature of the failure plays a huge role in the final cost. A cylinder that is simply weeping oil from its main gland seal due to normal wear and tear is a relatively straightforward fix. However, a cylinder that has suffered a major failure will be much more expensive to repair.
Common types of damage include:
- Bent Rods: Often caused by improper use or an impact. A bent rod must be professionally straightened, a process that requires specialised presses and expertise. If it cannot be straightened, a new rod must be manufactured from scratch.
- Scored or Scratched Rods: A scratch or gouge in the chrome surface of the rod will act like a knife, shredding any new seal you install. This damage requires the rod to be stripped and re-chromed.
- Scored or Damaged Barrel: Scratches on the inside of the cylinder barrel, often caused by contamination in the hydraulic fluid, will prevent a proper seal. This requires the barrel to be machined using a honing tool to restore a perfectly smooth surface.
- Internal Component Failure: Sometimes the piston itself or the gland can be damaged or cracked, requiring new custom parts to be machined in the workshop.
Factor 3: The Specific Repairs Needed
The price will directly reflect the workshop processes required. A standard reseal involves completely disassembling the cylinder, cleaning all components, inspecting them for wear, and replacing all seals, wipers, and O-rings.
If the rod is damaged, a full re-chrome is a more intensive process. The rod must be machined to remove the old chrome layer, polished to eliminate any scratches, and then put through an electro-plating process to apply a new, hard layer of industrial chrome. This is a specialised process that ensures the rod surface is perfect for the new seals. Similarly, barrel honing requires specific machinery and skilled operators to restore the internal finish of the cylinder tube.
Factor 4: Replacement Parts & Materials
Finally, the cost of the parts themselves contributes to the quote. A seal kit for a common brand of excavator might be readily available and reasonably priced. However, a seal kit for a rare or older piece of machinery may be harder to source and more expensive. The material of the seals also matters; high-temperature or high-pressure applications require specialised, costlier seal compounds. If hard parts like the piston, gland, or rod need to be replaced, the cost of the raw materials and the machining time will be a major factor in the final price.
Repair vs. Replace: Making the Smart Financial Decision
This is a critical question for any equipment owner. The answer usually comes down to a simple cost-benefit analysis.
When Repair is the Best Option
For the vast majority of cylinders on medium to large equipment used in mining, construction, and agriculture, repair is by far the most cost-effective solution.
- Significant Cost Savings: A professional repair, even a full rebuild, is almost always significantly cheaper than buying a new OEM (Original Equipment Manufacturer) cylinder.
- Faster Turnaround: Sourcing a new cylinder, especially for larger or less common machinery, can take weeks or even months of waiting for it to be shipped to Western Australia. A workshop repair is typically much faster.
- Quality and Durability: A properly rebuilt cylinder is restored to OEM specifications or better, ensuring a long and reliable service life.
When to Consider a Replacement
There are a few situations where buying a new cylinder makes more sense:
- Small, Common Cylinders: For some smaller cylinders on equipment like log splitters or tail lifts, the cost of labour to disassemble and repair can be close to the price of a new replacement unit.
- Catastrophic Failure: In rare cases, if the cylinder barrel is cracked or the mounting points have been torn off, the unit may be damaged beyond economical repair.

Your Repair Questions Answered (FAQ)
What is the typical turnaround time for a cylinder repair?
A standard reseal can often be completed in 2-3 business days. A more complex rebuild that requires re-chroming or machining may take 5-10 business days, depending on the extent of the work and workshop capacity. We always provide an estimated turnaround time with our quote.
What kind of warranty do you offer on rebuilt cylinders?
We stand by our workmanship. All our hydraulic cylinder repairs come with a comprehensive warranty that covers both the parts we use and the labour we perform, giving you complete peace of mind.
What are the signs that my hydraulic cylinder is failing?
The most common signs include visible oil leaks around the rod or seals, a noticeable loss of power or speed in the machine’s movements, “spongy” or jerky operation, and strange noises (like banging or knocking) when the cylinder is operating. If you notice any of these signs, it’s best to have the cylinder inspected promptly to avoid a more serious failure.
