Hydraulic System & Component

Maintenance and Repair

The following points should be kept in mind when

working on the hydraulic system or any component:

1. Any structure has limits of strength and durability.

To prevent failure of structural parts of hydraulic

components, relief valves which limit pressure to

safe operating values are included in the hydraulic

circuits.

2. Tolerance of working parts in the hydraulic system

is very close. Even small amounts of dirt or foreign

materials in the system can cause wear or damage

to components, as well as general faulty operation

of the hydraulic system. Every precaution must

be taken to assure absolute cleanliness of the

hydraulic oil.

3. Whenever there is a hydraulic system failure

which gives reason to believe that there are metal

particles or foreign materials in the system, drain

and flush the entire system and replace the filter

cartridges. A complete change of oil must be

made under these circumstances.

4. Whenever the hydraulic system is drained, check

the magnets in the hydraulic reservoir for metal

particles. If metal particles are present, flush the

entire system and add a new change of oil. The

presence of metal particles also may indicate the

possibility of imminent component failure. A very

small amount of fine particles is normal.

5. All containers and funnels used in handling

hydraulic oil must be absolutely clean. Use a

funnel when necessary for filling the hydraulic oil

reservoir, and fill the reservoir only through the

filter opening. The use of cloth to strain the oil

should be avoided to prevent lint from getting into

the system.

6. When removing any hydraulic component, be sure

to cap and tag all hydraulic lines involved. Also,

plug the ports of the removed components.

7. All hydraulic components must be dis-assembled

in spotlessly clean surroundings. During

disassembly, pay particular attention to the

identification of parts to assure proper reassembly.

Clean all metal parts in a clean mineral oil solvent.

Be sure to thoroughly clean all internal passages.

After the parts have been dried thoroughly, lay

them on a clean, lint-free surface for inspection.

8. Replace all O-rings and seals when overhauling

any component. Lubricate all parts with clean

hydraulic oil before reassembly. Use small

amounts of petroleum jelly to hold O-rings in place

during assembly.

9. Be sure to replace any lost hydraulic oil when

completing the installation of the repaired

component, and bleed any air from the system

when required.

10. All hydraulic connections must be kept tight. A

loose connection in a pressure line will permit

the oil to leak out or air to be drawn into the

system. Air in the system can cause damage

to the components and noisy or erratic system

operation.

Maintenance Hints

Three simple maintenance procedures have the

greatest effect on the hydraulic system performance,

efficiency and life. Yet, the very simplicity of them may

be the reason they are so often overlooked. What are

they? Simply these:

Change filters annually. The filters will need 1.

to be changed more often depending on

the operating conditions. Dirty, dusty, high

moisture environments may cause the

hydraulic system to be contaminated more

quickly.

Maintain a sufficient quantity of clean hydraulic 2.

oil of the proper type and viscosity in the

hydraulic reservoir.

Keep all connections tight.3.
