Understand the Manufacturer’s Guidelines

7004638
The first step in creating a maintenance schedule is to consult the manufacturer’s guidelines. Sauer Danfoss provides specific recommendations on maintenance and service intervals, which vary depending on the model and application. Reviewing these guidelines will give you a baseline for establishing your maintenance schedule.
Identify Critical Maintenance Tasks
Hydraulic pumps require several routine maintenance tasks to function optimally. Key tasks to consider include:
Fluid Level Checks: Regularly check hydraulic fluid levels to ensure they are within the recommended range.
Fluid Quality Assessment: Monitor the condition of the hydraulic fluid for signs of contamination or degradation.
Filter Replacement: Replace filters as per the manufacturer’s recommendations to avoid blockages and ensure smooth operation.
Seal Inspections: Regularly inspect seals and gaskets for wear and leaks.
Component Lubrication: Ensure all moving parts are adequately lubricated to reduce wear and friction.
Visual Inspections: Conduct routine inspections for leaks, vibrations, or unusual noises that might indicate a problem.
Determine the Frequency of Maintenance Tasks
Once you have identified the critical maintenance tasks, the next step is to determine how often these tasks should be performed. This can be based on several factors, including:
Manufacturer Recommendations: Refer to the maintenance intervals suggested by Sauer Danfoss.
Operating Conditions: Consider the environment in which the hydraulic pump operates. Harsh or dirty conditions may require more frequent maintenance.
Usage Patterns: High usage rates can lead to increased wear and necessitate more frequent maintenance.
