- Measure Hydraulic Pressure:
- Use a hydraulic pressure gauge to measure the pressure in the hydraulic lines feeding the right drive motor. Compare the readings with the specifications in the service manual to determine if the system is operating at the correct pressure. Low pressure readings may indicate a blockage or restriction in the line.

Once the problem has been diagnosed, the next step is to implement the appropriate solution. Here are some potential solutions based on the type of issue identified:
- Repairing or Replacing Leaking Hoses:
- If a hydraulic hose is leaking, it will need to be repaired or replaced. For minor leaks, a hose clamp or patch may temporarily fix the issue, but it is best to replace the damaged hose with a new one to ensure long-term reliability. Be sure to use hoses that meet the manufacturer’s specifications for pressure and temperature tolerance.
