Can a hydraulic cylinder be repaired?
In some cases, a hydraulic cylinder may be so badly damaged that replacement is the only course of action that makes sense. However, in most cases, that is not true. Most cylinder damage can be repaired by skilled professionals back to the condition, or near the condition, it was in when it was new.
What causes a hydraulic cylinder to fail?
Hydraulic cylinders fail by physical damage or by deterioration of their seals. Physical damage to a hydraulic cylinder is usually from an external source, such as another machine or a falling object. Damage can take the form of a bent rod or dented barrel, both of which could prevent the cylinder from stroking fully.

The extend test is to check if there is any shaft seal or piston leakage.
Can hydraulic cylinders be welded?
Welded hydraulic cylinders have no tie rods. Instead, the barrel is welded directly to the end caps and the ports are welded to the barrel. The front rod gland is generally bolted or threaded into the cylinder barrel, which allows the piston rod assembly and the rod seals to be removed for service.
How long do hydraulic cylinder seals last?
If your fluid is clean, if you're keeping it cool. In severe applications, really, the seals should last forever. If you look at, say, a modern automobile engine that can last 300,000 or 400,000 miles with very little changeover of internal components, why can't your hydraulic system be the same?

Can welded hydraulic cylinders be repaired?
Welded cylinders come in welded designs hence difficult to repair, but rod seals and assembly of piston rods can easily be removed for service. On the other hand, tie-rod cylinders are easily repaired or, if necessary, repacked.
What does it mean to repack a hydraulic cylinder?
A repacking kit Repacking kits contain replacement parts for various components of the cylinder. Often, parts are damaged upon disassembly; it's important to keep replacement parts on hand so the lift can be reassembled and used immediately.

Why does a cylinder balloon?
Once the tube balloons , the correct tolerance between the piston seal and tube wall is lost and high-pressure fluid bypasses the seal. This high velocity fluid can erode the seal and localized heating caused by the pressure drop across the piston reduces seal life.
What happens when the internal bearing areas in the gland and at the piston are insufficient to carry the thrust transferred to the
If the internal bearing areas in the gland and at the piston are insufficient to carry the thrust transferred to the cylinder, excessive load is placed on the rod and piston seals. This results in deformation and ultimately premature failure of the seals.
Why do hydraulic cylinders bend?
Bending of hydraulic cylinder rods can be caused by insufficient rod diameter or material strength, improper cylinder mounting arrangement or a combination of all three. Once the rod bends, excessive load is placed on the rod seal resulting in premature failure of the seal.
Do all hydraulic cylinders have to be made equal?
Not all hydraulic cylinders are made equal. So if you have hydraulic cylinders that suffer recurring failure, it's likely that modifications to the cylinder are required to break the vicious circle of failure and repair.
A Review of Hydraulic Cylinder Failure
A hydraulic cylinder is made up of many parts, small and large. The most common components that fail are the barrel that contains many of the other parts, the cylinder cap, the cylinder head, the piston rod, the piston that transfers motion to the piston rod, and the many seals and bearings of the cylinder.
Cost of Repair and Replacement of Hydraulic Cylinders
It is possible that a hydraulic cylinder can become so damaged that there is no choice but to completely replace it. Most of the time, however, that is not the case. A cylinder can be repaired by skilled experts to resemble or closely resemble its original condition.
Other Considerations for Deciding Whether to Repair or Replace Cylinders
The decision to repair or replace a hydraulic cylinder has many considerations besides cost that should be taken into account. If one were to make a pro and con list, cost would only be one of the many factors that are listed in order to make an educated and thoughtful decision.
Benefits of Hydraulic Cylinder Repair
The number of benefits to repairing a hydraulic cylinder over replacing it is substantial. Often, only one specific component is damaged or in need of repair, and not the entire cylinder.

What causes hydraulic cylinder seal failure?
Oil Contamination. contamination within the system is a main cause for the hydraulic cylinder seal failure. Hydraulic oil contamination increases the risk of internal leakage as well as reducing the control of flow and pressure in valves, which could eventually waste horsepower and overheat.
Why is my hydraulic cylinder seal brittle?
High Temperature. If hydraulic cylinder seals look hard and brittle, or the seal lip or body is eroding, the temperature of the oil in the cylinder may be too high. High temperature for a long period of time may result in the seal losing functionality, either by excessive compression or damage to the seal material.
What happens if a hydraulic cylinder is damaged?
This leads to misalignment and wear or more permanent damage.
How to remove air from a cylinder?
Remove any air from the cylinder by using the directional control valve and stroking the cylinder numerous times; Place the piston rod mid-stroke and close the ball valve; Direct the fluid flow to the side of the cylinder where the rod is located ;
What is pressure intensification?
The pressure intensification that is created helps to keep the piston in one position along the entire cylinder to make sure that all the seals are functional and there is no leakage.
What is hydraulic cylinder maintenance?
Hydraulic cylinder maintenance here can often be as simple as a re-chrome or polish to repair a corroded or damaged rod. If a cylinder rod is beyond repair, a replacement is the best course of action.
Why is it important to maintain a hydraulic cylinder?
Regular maintenance on your hydraulic cylinder is important for optimal performance. Make sure you keep a close eye on the condition of the cylinder rod for any signs of corrosion, pitting or wear. Too much moisture can cause corrosion; whether this is from the air or from within the hydraulic fluid itself.

I just pulled the main boom cylinders off a komatsu excavator to have them resealed. I don't have the time to do it myself so I dropped them off at the local hydraulic shop today and asked what they were gonna charge me. The quote was $500 each. I think I heard my jaw hit the floor.

On the bigger cylinders...from ten ton excavators upward...the problem is that locking 'nut' which holds the seal pack in place, is cranked up at the factory with a torque multiplier..they are TIGHT ...On the odd occasion they will spin off...the best way to hold that ram is to try to replace the seal kit whilst the static end of the ram is still afixed to the machine..we have laid boom rams down onto the truck deck...set it all up with blocks etc to use a huge one inch drive socket...no luck....so generally you come second.

i guess that i am just cheap, i haven't dealt with boom cylinders before, mostly manufacturing equipment and smaller machinery cylinders. I did not know there was a difference. It sounds like I would not have been able to deal with it anyway if you have to get it that tight.

had a problem cyl--went threw 3 hyd shops and on and off machine 5 times befor it was fixed.The 2 shop cut the rod to get packing off, (unknown to me)when they welded it back it was off just enough I couldn't get the pin in.Thats when they told me they did all of them that way because it takes a expensive torque wrench to spin the nut off (+or-2000ft pds)The last shop was the dealer and they had the eq to fix it.Ended up rechroming rod and honeing cyl--$2500.00.I would suggest if anyone is looking for hyd repair shop to ask if they have the eq.
