CASE Boom Cylinders: Spare Parts in Stock for Your Construction Machines

Codimatra offers a dedicated inventory of CASE boom cylinders, covering both hydraulic excavators and backhoe loaders from the 580, CX, and WX series. Each part undergoes a strict quality check before shipping, ensuring performance that meets professional site requirements.

For repairs, you have two options depending on the condition of your original cylinder:

• Used complete cylinders, ideal when the rod or body is damaged
• Seal kits, sufficient when the metal structure remains intact

Our team is available Monday to Friday from 8 AM to 6 PM and can quickly identify the correct reference for your machine using the serial number. Responses outside these hours are guaranteed within 24 hours.

Compatible Models: CASE Backhoe Loaders and Excavators

• CASE backhoe loaders 580G, 580K, 580SK, 580SL, and 580SM are among the most covered models.
• The 580SLE and 580SM+ series are also supported, with specific references available.
• For wheeled excavators, the WX150 and WX165 ranges have boom cylinders in stock.
• Hydraulic excavators CX225SR and CX240 are compatible with tested, ready-to-use boom cylinders.
• The CASE 1088 and 1288 models are included among references for heavy-duty machines.
• Older series 580B, 580C, and 580F are also supported, thanks to references like G105547.
• For 590SR models, kits and complete cylinders are referenced with controlled shipping times.

580 G, 580 K, 580 SK Backhoe Loaders and Derived Series

On the 580 series backhoe loaders, the boom cylinder operates under high hydraulic pressure, which explains the frequent wear of sealing rings. Reference 1542919C1 covers the 580SK and its direct variants, while 1543274C1 corresponds specifically to the rear boom bucket cylinder of the 580G.

Note that the 580K and 580SK share some but not all references with the 580SL and 580SM. Checking the serial number before ordering prevents any compatibility errors.

Seal kits often offer the fastest repair option when the cylinder’s structure is sound — allowing workshop repair without full hydraulic body replacement.

Wheeled Excavators WX150, WX165, CX225SR and Others

• WX150 and WX165 wheeled excavators use boom cylinders sized differently from 580 backhoe loaders.
• The CX225SR, with a short turning radius, requires a boom cylinder with dimensions adapted to its compact design.
• Dedicated seal kits for the CX240 are referenced and immediately available at Codimatra.
• Wheeled excavators face more vibrations during movement, accelerating rod seal wear.
• A visible leak at the base of the rod on a WX150 generally indicates a worn wiper seal needing prompt replacement.
• The boom’s serial number, distinct from the machine number, may be requested to refine the exact cylinder reference.
• CX and WX models have their own hydraulic references and are not interchangeable with 580 series parts.

Complete Cylinder or 580 G Seal Kit: What to Order?

The decision is primarily based on a precise visual inspection of the installed cylinder. If the rod shows deep scratches, corrosion, or deformation, replacement with a used complete cylinder is necessary. Seal replacement alone cannot compensate for a damaged metal sliding surface, which would result in rapid failure of new components.

Conversely, an oil leak localized on a cylinder body whose structure and rod are sound suggests using a seal kit. This approach restores the hydraulic element while keeping the original structural components. It is a preferred option for routine maintenance on machines like the CASE 580G when the cylinder shows no geometric defects.

An experienced technician can decide in under ten minutes after a simple visual check of the rod surface’s condition and body alignment. If unsure whether a simple refurbishing is feasible, contact Codimatra with your machine’s serial number for tailored technical advice based on your equipment’s condition.

What Is the Cost to Repair a CASE Boom Hydraulic Cylinder?

• Replacing just a rod seal is a moderate investment in spare parts, excluding labor costs.
• The price of a reconditioned used CASE boom cylinder varies depending on the rarity and complexity of the machine model.
• Workshop labor typically ranges from one to three hours depending on part accessibility on the machine.
• For CX225SR or CX240 excavators, intervention costs are generally higher due to more complex access to boom components.
• Choosing rigorously tested used parts significantly reduces expenses, often by more than half the cost of a new manufacturer cylinder.
• Using an adaptable seal kit compliant with original quality standards is a cost-effective way to maintain your maintenance budget.
• Requesting a personalized quote including your machine’s serial number is the only way to get an accurate price and avoid ordering errors.
