John Deere CCU1713.0 – CCU: Hydraulic Filter Replacement Required

The hydraulic oil filter is restricted and requires replacement. This is a maintenance-related alert triggered by a pressure sensor that detects a significant pressure drop across the filter, signaling that it is clogged with contaminants and no longer functioning effectively.

1. 1

   Restart the tractor to verify if the code clears. A power cycle can sometimes reset communication glitches.

2. 2

   Check the hydraulic oil level using the sight glass or dipstick and top off as needed, as low oil can cause pressure issues.

3. 3

   Visually inspect the hydraulic system for any obvious signs of oil leaks.

4. 4

   If the oil level is correct, there are no visible leaks, and the code remains active, the hydraulic filters are restricted and must be replaced.

1. 1

   Warm the oil

   Operate the tractor to warm the hydraulic oil, which will help it drain more completely.

2. 2

   Park safely

   Park the tractor on a level surface, lower all implements to the ground, stop the engine, and engage the park lock.

3. 3

   Drain the hydraulic oil

   Place a suitable container under the drain plugs. Remove the drain plug from the rear differential case and the transmission housing to drain the oil.

4. 4

   Remove old filters

   Locate the two transmission/hydraulic filters (for 8030 series). Use a filter wrench to turn and remove them. Ensure the old filter gaskets (packings) are also removed.

5. 5

   Install new filters

   Apply a thin film of clean hydraulic oil to the gaskets of the new filters. Install the new filters and hand-tighten them until they make contact with the mounting surface, then tighten an additional 2/3 to 1 turn.

6. 6

   Reinstall drain plugs

   Once the oil has completely drained, reinstall the drain plugs.

7. 7

   Refill hydraulic oil

   Refill the system with the correct type and amount of John Deere Hy-Gard™ hydraulic oil.

8. 8

   Check for leaks and final oil level

   Start the engine and let it run for several minutes, checking for any leaks around the new filters and drain plugs. Stop the engine, wait at least five minutes, and then recheck the oil level, adding more if necessary.
