How to Change Hydraulic Oil

Regularly changing the hydraulic oil is a cornerstone of maintaining the optimal performance and longevity of your New Holland skid steer. This process not only replenishes the lubricating and cooling properties of the fluid but also removes contaminants that can accumulate over time. Here are the essential steps to follow when flushing and refilling the hydraulic fluid in your New Holland skid steer:

Step-by-Step Guide:

1. Gather Necessary Items and Tools: Before you begin, ensure you have all the required tools, such as wrenches, a drain pan large enough to hold the old hydraulic fluid, a new hydraulic filter, the correct type and quantity of new hydraulic oil, clean rags, and safety equipment (gloves and eye protection).
2. Drain the Old Hydraulic Oil: Locate the hydraulic oil drain plug, typically found at the lowest point of the hydraulic reservoir. Place your drain pan underneath the plug and carefully remove it. Allow the old oil to drain completely.
3. Clean the Hydraulic Pump and Reservoir: While the oil is draining, inspect the hydraulic pump and reservoir for any visible debris or sludge. Clean these components as thoroughly as possible using clean rags. If significant contamination is present, consider a more thorough system flush.
4. Replace the Hydraulic Filter: Remove the old hydraulic filter and carefully dispose of it. Apply a thin film of new hydraulic oil to the rubber gasket of the new filter to ensure a good seal. Screw the new filter on securely, tightening it according to the manufacturer's instructions (usually hand-tight plus a quarter turn).
5. Refill with New Hydraulic Oil: Once the old oil has completely drained and the filter is replaced, carefully refill the hydraulic reservoir with the correct type and amount of new hydraulic oil as specified in your operator's manual. Use a clean funnel to prevent contamination.
6. Start the Skid Steer and Check for Leaks: Start the engine and allow the hydraulic system to circulate the new oil. Operate the hydraulic controls slowly through their full range of motion to ensure the new oil reaches all components and to bleed any trapped air. While the system is running, carefully inspect all connections, hoses, and seals for any signs of leaks.
7. Check Oil Level and Top Off: After running the system for a few minutes, shut off the engine and allow the oil to settle. Check the hydraulic oil level using the dipstick or sight glass and top off if necessary to reach the correct operating level.
8. Dispose of Used Oil Safely: Properly dispose of the old hydraulic oil and the old filter in accordance with local environmental regulations. Many auto parts stores or recycling centres accept used motor oil and hydraulic fluid.
