Key Features

• Comprehensive hydraulic system testing guide.
• Detailed procedure for pressure and efficiency evaluation.
• Recommendations for safe equipment handling during testing.

Benefits

• Ensures hydraulic system operates within optimal pressure range.
• Helps identify and rectify issues with pressure and efficiency.
• Improves machine reliability and performance.

Usage Recommendations

• Step 1: Connect a 400 PSI (28 bar) pressure gauge to the test port at the hydraulic filter outlet.
• Step 2: Run the engine and heat the oil to at least 125u00b0F (52u00b0C) by cycling the bucket control lever as explained.
• Step 3: Keep the engine at full throttle, record the pressure and ensure it’s between 130 to 150 PSI (9.0 to 10.3 bar).
• If pressures are correct, read further instructions on Section 8002, Page 6 for next steps.
• Follow additional procedures to inspect components, ensure hydraulic line routing, and adjust the charge relief valve if needed.
• For safety, raise the machine on supports when performing tests with the engine running to mitigate risks associated with parking latch failure.
• Use a flow meter to verify gear pump efficiency as described in Section 8002.
