Cleaning Transmission Filter Screen (IVT Only)

IMPORTANT: For tractors with IVT refer to your John Deere dealer with any question you have on removing hydro control valve and/or transmission filter screen.

When working with hydraulic components, cleanliness is essential and ANY FOREIGN MATERIAL (DIRT) can damage equipment! Clean area around the hydro control valve thoroughly with steam cleaner prior to removing it, then make sure valve is clean before installing it. On IVT transmissions, do not remove screen unless it is dirty.

IMPORTANT: Removing hydro control valve requires a 1 1/4 in. (deep broach) deep well socket to avoid damaging control valve.

1. Remove IVT transmission bottom cover shield if not already removed.

IMPORTANT: Make sure wiring harness (B) is disconnected and kept out of the way of any dripping oil before removing screen access plug. Oil in wiring harness connectors will damage equipment.

2. Remove connectors (A) on control valves then tuck wiring harness out of the way.

NOTE: Make sure 1 1/4 in. deep well socket has a broach (C) deep enough that control valve is not damaged when it is removed.

3. Using a 1 1/4 in. deep broach deep well socket, remove CU hydro valve (D).

4. Remove screen access plug (E) at front of transmission, then remove screen (F).

NOTE: For tractors with Independent Link Suspension, carefully flex Independent Link Suspension tube (G) down enough to remove screen (F).

5. Flex steel tube across the front of the screen slightly to allow screen to be pulled out of transmission case.

6. Remove filter screen and wash carefully in solvent. Blow dry with compressed air before reinstalling screen.

7. Install screen in transmission, front screen plug, and bottom drain plug.

8. Reinstall control valve and wiring harness connectors.

9. Reinstall all drain plugs after oil has drained.

10. Refill with transmission/hydraulic oil specified in Fuels, Lubricants, and Coolant section.
