Importance and individuality of hydraulic maintenance schedules
The best schedule for preventive maintenance of individual machines can only be determined over time by understanding the usage and operating conditions of the various hydraulic components. For example, an industrial piston pump might only need to be replaced after 10,000 hours of full load running while a mobile pump might need replacing after 1000 hours of full-load operation. The difference is primarily due to design and operating conditions although good maintenance and fluid quality will have a major effect.
Therefore the following schedules are intended as guidelines. Experience and operating conditions will determine actual schedules. Refer to OEM datasheets for specific maintenance instructions.
Visual inspection checks
Contamination and test meters
Record all non-conformities in the maintenance record book.
