  3. Lubricate the new filter packing with hydraulic oil only.

    IMPORTANT: Make sure old packings are removed before installing new filters.

  4. Install and hand tighten both new filter elements.

  5. Before refilling transmission/hydraulic oil, check all drain plugs to be sure they are correctly installed.

  6. Refill with Transmission/Hydraulic oil specified in Fuels, Lubricants, and Coolant section.

    IMPORTANT: Fill differential housing with oil. Start engine and run at 900 rpm until clean oil reservoir level indicator light goes off (approximately 2 minutes). Refilling clean oil reservoir will take a few minutes.

    NOTE: Oil temperature should be approximately 45° C. See Changing Display Functions in the CommandCenter section to determine oil temperature.

    Sight glass observations will be significantly higher with hotter oil temperatures and lower with colder oil or if engine has not run long enough.

  7. Operate engine at approximately 1000 rpm for at least one minute.

    B - Filler Cap


  8. Stop engine and wait an additional three minutes for oil to settle back into differential case.

  9. Ensure rear hitch is in lowered position.

  10. Observe oil level in sight glass (A). Oil level should be between the marks on the glass. Optimum level is at the top mark.

    IMPORTANT: Oil level above the top mark on sight glass can result in power loss and heat generation during transport.

    If oil level is below the lower mark, remove filler cap (B) and add hydraulic oil.

  11. Start and operate engine several minutes, then check for leaks.

  12. Stop engine and recheck oil level after a minimum of five minutes.

  13. Add oil as necessary.
