Apply Superglue to the scratch. When it's thoroughly dry, use some fine emery paper over it . Of course that wont fix a damaged seal. There are places that can re-chrome a rod or replace with stock rod but unless it is a very special size or made of unobtainium it may be cheaper to replace the whole cylinder.
How do you polish a hydraulic cylinder rod?
Can a pitted hydraulic ram be repaired?
Minor pits in hydraulic cylinders can go through a repair and restoration process . Professional repair specialists can help fill in the pits and restore the piston rods. Once repairs are complete, the repair professionals can run full tests on the hydraulic cylinders.
Are hydraulic cylinder rods hardened?
Hydraulic cylinder piston rods are induction hardened in order to increase the resistance to damage from unantici- pated external impact in applications where there is risk for such; examples are piston rods for hydraulic cylinders in excavators and loaders and for power-steering cyl- inders.
How do you repair a rusty hydraulic cylinder?
How do I keep my hydraulic cylinder from rusting?
Hydraulic cylinders can be ruined by pit rust if left extended and not protected. They are expensive to replace. You can protect your cylinders by (a) storing them in a retracted position , (b) storing them inside or (c) coating any exposed portion of the rods with heavy grease.

How do you fix a pitted cylinder?
How do you fix hydraulic ram?
How do you replace a hydraulic cylinder seal?
Are hydraulic cylinders chrome plated?
The chrome plating used for hydraulic cylinder rods is called “Hard Chrome” .
How do you Chrome a cylinder?
What are hydraulic cylinder rods made of?
Therefore, the materials and coating of the hydraulic cylinder is of the utmost importance. Most commonly, the cylinder rod is made of steel or stainless steel and is then coated with Hard Chrome Plating (HCP).
Do hydraulic cylinders rust?

Can you clean pistons with WD40?
WD40 works great on carbon , stuff rags on top of the pistons and soak them wit WD and let set a couple hours resoak and, it will take of the carbon with minimal scrubbing.
What oil do you use to honing a cylinder?
For best results whenever you hone, Brush Research Manufacturing (BRM) recommends using Flex-Hone® oil .
Can you hone rusty cylinders?
If there is more rust than steel wool will easily remove, the next step would be to use a flex hone , which is a round wheel with aluminum balls on it. This attaches to a drill and cleans the cylinders quite well at a microscopic level without damaging the cross-hatching that machine boring provides.
What causes a hydraulic cylinder not to move?
Worn or Damaged Piston Seals
Having insufficient hydraulic fluid in your system causes cylinders to become hydraulically locked and unable to fully retract or extend. Worn seals can also cause misalignment issues between the seal and cylinder rod, which may cause trouble when retracting hydraulic cylinders.
How do you check a hydraulic cylinder for internal leaks?
How do you test a pneumatic cylinder?
Figuring Out The Bore Size Of A Pneumatic Cylinder. You can determine the area inside of a pneumatic piston simply by using the formula F=PA, where P is pressure and A is area . Product F is equal to the total force. Therefore you could solve for the area by using A=F/P and plugging in the two figures you already have.
