John Deere 1713.16 – EPC, UIC, or VCU: Hydraulic Oil Filter Restricted

The filter alarm level 2 switch at the hydraulic oil filter remains closed for more than three seconds, indicating the differential filter pressure has reached 425 kPa (4.25 bar; 62 psi) ± 25 kPa (0.25 bar; 3.6 psi). This indicates that the hydraulic oil filter is significantly dirty or clogged, restricting hydraulic oil flow.

1. 1

   Verify operating conditions: ensure the transmission oil temperature is above 28°C (82°F) and the engine is running above 700 rpm, as the differential pressure switch will not accurately trigger below these thresholds.

2. 2

   Inspect the hydraulic filter housing and associated components for external damage or severe blockages.

3. 3

   Check the hydraulic system and old oil for signs of severe contamination, metal shavings, or debris (if heavy debris is present, a simple filter change will not solve the underlying mechanical failure).

4. 4

   Verify fluid viscosity: ensure the correct hydraulic fluid is being used (e.g., John Deere HY-GARD), as incorrect or low-viscosity fluids can cause pressure anomalies.

1. 1

   Prepare the Machine

   Park the machine on a level surface, shut down the engine, and allow the hydraulic system to depressurize and cool slightly.

2. 2

   Locate the Hydraulic Filter(s)

   Locate the hydraulic oil filter housing. (Note: Some heavy equipment, like the 3520 Harvester, utilizes three separate hydraulic filters that should be changed simultaneously when this code appears).

3. 3

   Remove the Filter

   Unscrew the filter housing plug/cap, remove the restricted hydraulic oil filter element, and discard it safely.

4. 4

   Clean and Inspect

   Clean the inside of the filter housing. Inspect the old filter for excessive metal flakes.

5. 5

   Install New Filter

   Insert the new OEM hydraulic oil filter element and securely tighten the plug/housing.

6. 6

   Check Fluid Levels

   Top off the hydraulic fluid using approved John Deere HY-GARD or BIO-HY-GARD II (Do NOT use HY-GARD Low Viscosity unless specifically called for by your exact model).

7. 7

   Reset and Test

   Start the engine, bring the RPMs over 700, and allow the transmission oil to warm up past 28°C (82°F). Monitor the differential pressure to ensure the code clears and does not return.
