Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Do not check for leaks with your hands. Pin hole (very small) leaks can result in a high velocity oil stream that will be invisible close to the hose. This oil can penetrate the skin and cause personal injury. Use cardboard or paper to locate pin hole leaks.
Implement System
When you are troubleshooting a problem, a visual inspection of the system is the first step. Turn the engine OFF before you inspect the machine. Lower the implements to the ground. Place all controls in the PARK or HOLD position. After performing the visual inspection, check the operation of the machine and note any unusual noises.Check the Hydraulic Oil Tank Level
Fill the hydraulic oil tank to the correct level in the sight glass.ReferenceRefer to the Operation and Maintenance Manual, SEBU7234, "Hydraulic System Oil Level - Check".Expected Results
The oil level is at the FULL level in the sight glass.Results
OKAY: Proceed to "Check for Oil Leaks".Check for Oil Leaks
Inspect these components for leaks and for damage: oil lines, hoses and fittings.
Look under the machine for oil that has leaked from the machine onto the ground.Expected Results
No leaks exist.Results
OKAY: Proceed to "Check the Electrical System".
NOT OKAY: Repair all leaks. Check the machine for the original problem. If the conditions are not resolved, proceed to "Check the Electrical System".Check the Electrical System
Inspect the wires and check the electrical connectors to the component that is suspect.Expected Results
The wires and the electrical connectors are not damaged. The electrical connectors are clean.Results
OKAY: Proceed to "Check for Oil Contamination".
NOT OKAY: Replace any damaged wires. Replace any damaged electrical connectors. Ensure that all of the seals are properly in place. Check the machine for the original problem. If the conditions are not resolved, proceed to "Check for Oil Contamination".Check for Oil Contamination
Use the 175-7546 Oil Filter Cutter Gp to cut open spin-on filters in order to inspect the filter media for contaminants.
Check the oil for air and for excessive particles. Air in the oil causes the oil to foam. If particles are in the oil, the oil appears sandy.
Check the hydraulic oil by taking an oil sample from the S O S Sampling Valve next to the pressure reducing valve.ReferenceRefer to Operation and Maintenance Manual, "Hydraulic System Oil Sample - Obtain".Check for Particles in the Oil
Shiny steel particles indicate a pump failure.
Rubber particles indicate a seal failure or hose failure.
If metal particles or rubber particles are found, then all components of the implement, steering, and fan systems must be washed.
Replace all damaged parts with
