Hydraulic Cylinder Repair for Ag and Industrial Equipment

Hydraulic Cylinder Problems Luft Evaluates

• Hydraulic fluid around the rod, gland, ports, fittings, or cylinder body
• Cylinders that drift, will not hold position, or lose force
• Slow, uneven, or chattering movement
• Bent, scored, dented, corroded, or otherwise damaged rods
• Worn seals, bearings, glands, pistons, barrels, or mounting components
• Cracked, loose, damaged, or deformed mounts and related components
• Older or unusual cylinders where an off-the-shelf replacement may not be practical

These symptoms do not always identify the cylinder as the only problem. Valves, pumps, plumbing, contamination, pressure, alignment, side loading, and other system conditions can create similar symptoms. The correct path depends on the equipment, application, condition, and inspection findings.

A Practical Repair Process

1. Review the Application

Luft starts with the equipment use, operating symptoms, cylinder identification, dimensions, visible damage, and repair history.

2. Inspect the Cylinder

The shop reviews the serviceable components and condition of the rod, seals, gland, bearing, piston, barrel, ports, welds, and mounts as the job requires.

3. Compare the Options

Depending on the findings, the practical path may involve repair, rebuilding, machining or fabricating a component, correcting mounting damage, using an appropriate outside service, or replacing the cylinder.

4. Confirm the Scope

Luft discusses the recommended work and known scope before moving forward. Additional findings are handled according to the job and customer approval.

Equipment and Industries Served

What to Bring or Send

• The cylinder, when it can be removed and transported safely
• Equipment make, model, application, and cylinder identification
• Clear photos of the cylinder, rod, mounts, ports, and damaged areas
• Bore, rod diameter, stroke, and mounting dimensions when known
• A description of the symptom and when it occurs
• History of impact, overload, contamination, alignment trouble, or prior repair

Recent Project: Truck Hydraulic Repair

A regional customer brought Luft a truck that needed hydraulic cylinder repairs and broader work to its hydraulic system. The job required looking beyond a single leaking component, working through the cylinders and related system needs, and completing the appropriate repair work so the truck could return to service.

This type of project reflects Luft’s practical advantage: hydraulic repair can be supported by the shop’s machining, welding, fabrication, material, and equipment-repair capabilities when the inspected job requires them.

Service Area

Luft Machine is located at 413 Riverside Drive in Sterling, Colorado. The shop primarily serves Sterling, Logan County, Northeast Colorado, and nearby regional operators. Field-service availability depends on the location, timing, equipment, and job scope.

Frequently Asked Questions

Does Luft repair every type of hydraulic cylinder?

Luft evaluates appropriate agricultural, industrial, construction, truck, trailer, municipal, and equipment applications. The cylinder’s construction, damage, parts availability, application, and safety requirements determine whether Luft can recommend a practical repair path.

Can a leaking cylinder always be fixed with new seals?

No. A seal problem may also involve rod damage, bearing wear, barrel condition, alignment, contamination, or another hydraulic-system issue. Inspection is needed before deciding that a reseal is enough.

Can Luft quote the repair from a photo?

Photos and equipment information are useful for an initial conversation, but a meaningful repair quote may require the cylinder, measurements, disassembly, or inspection because internal wear is not visible in a photo.

Does Luft provide field support?

Luft supports appropriate mobile welding and field-repair needs. Availability depends on the location, job, timing, and scope. Some hydraulic-cylinder work is better completed in the shop.
