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 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 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 steering charge filter.Reference: Refer to (D8R and D8T) Operation and Maintenance Manual, SEBU9416, "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 new parts.Reference: Refer to (D8R and D8T) Disassembly and Assembly, M0078027Expected Results
The original problem is resolved.Results
OKAY: Stop.
NOT OKAY: The cause of the problem is uncertain. Contact technical support with the information that has been gathered.Power Train 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 attachments 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 Fluid Levels
Fill the oil reservoirs to the correct level.Reference: Refer to (D8R and D8T) Operation and Maintenance Manual, SEBU9416Expected Results
The oil levels are at the correct level.Results
OKAY: Proceed to "Check the Level of the Final Drive Oil".
NOT OKAY: Add oil if the oil level is low. Drain oil if the oil level is high. Maintain the correct oil levels. Check the machine for the original problem. If the conditions are not resolved, proceed to "Check the Level of the Final Drive Oil".Check the Level of the Final Drive Oil
Position one final drive so that the oil level mark is horizontal.
Remove the check/fill plug at the final drive.
Use the final drive oil level mark to check the level of the final drive oil.
Repeat the procedure to check the final drive oil level for the other side of the machine.Reference: Refer to (D8R and D8T) Operation and Maintenance Manual, SEBU9416, "Final Drive Oil Level - Check"Expected Results
The oil level is at the bottom of the filler plug opening.Results
OKAY: Proceed to "Check for Oil Leaks".
NOT OKAY: Add oil if the level of the oil is low. Drain oil if the level of the oil is high. Inspect the seal that is used for the
