Maintenance of Hydraulic Systems (page 2)

Preventive Maintenance

Preventive Maintenance of a hydraulic system is very basic and simple and if followed properly can eliminate most hydraulic component failure. Preventive Maintenance is a discipline and must be followed as such in order to obtain results. We must view a PM program as a performance oriented and not activity oriented. Many organizations have good PM procedures but do not require maintenance personnel to follow them or hold them accountable for the proper execution of these procedures. In order to develop a preventive maintenance program for your system you must follow these steps:

1st: Identify the system operating condition.
       a. Does the system operate 24 hours a day, 7 days a week?
       b. Does the system operate at maximum flow and pressure 70% or better during operation?
       c. Is the system located in a dirty or hot environment?

2nd: What requirements does the Equipment Manufacturer state for Preventive Maintenance on the hydraulic system?

3rd: What requirements and operating parameters does the component manufacturer state concerning the hydraulic fluid ISO particulate?

4th: What requirements and operating parameters does the filter company state concerning their filters ability to meet this requirement?

5th: What equipment history is available to verify the above procedures for the hydraulic system?

As in all Preventive Maintenance Programs we must write procedures required for each PM Task. Steps or procedures must be written for each task and they must be accurate and understandable by all maintenance personnel from entry level to master.

Preventive Maintenance procedures must be a part of the PM Job Plan which includes:

Ų Tools or special equipment required performing the task.

Ų Parts or material required performing the procedure with store room number.

Ų Safety precautions for this procedure.

Ų Environmental concerns or potential hazards.
