Transmission-Hydraulic Oil and Filters

Prevent premature axle failure. Carefully follow drain and fill procedure.

Recalibrate transmission only if transmission shift characteristics change after transmission oil and filter change. See Transmission Calibration in Service - General Information section of this Operator’s Manual.

Maximum transmission/hydraulic oil reservoir/axles volume is 265.5 L (71.0 gal), depending on option configuration. Select appropriately sized containers for draining oil.

  1. Park tractor on level ground, place transmission in PARK and shut engine off. Allow oil to cool for few minutes.

  26. Lubricate new filter O-rings with hydraulic oil and install filters. Tighten one-half turn after O-rings contact filter housing base.

  27. Replace hydraulic oil or axle oil filters every 1500 hours or when indicator lamp illuminates.

    Remove hydraulic oil filters (S), on left-hand side of gudgeon.


  28. Replace axle oil filter (T), located next to hydraulic oil filters (S).

  29. Lubricate hydraulic oil and double reduction axle oil filter O-rings with hydraulic oil and install on tractor. Tighten one half turn after O-ring contacts filter housing base.

  30. Hydraulic oil reservoir does not hold all system hydraulic oil . Transmission and front and rear axles also hold additional system oil.

    If possible, check oil level prior to first start of day. Ambient temperature should be 7° C. (45° F) or above. Oil level in the reservoir will fluctuate depending upon the volume of oil exchanged with an attached implement.

    For applications or implements requiring high volumes of oil transfer (for example - large air seeders or pulling 3 scrapers), hydraulic reservoir can be filled up to High Volume Takeout Oil Mark 58.5 L (15.4 gal) above MIN COLD.

  31. Reinstall and tighten hydraulic reservoir fill cap.

  32. Fill transmission with prescribed quantity of oil to ensure lubrication of transmission lube pump at startup.

    RXA0161072
    RXA0161072-UN-16OCT17

    Prefill transmission with 37.9 L (10.0 gal) of transmission-hydraulic oil at fill tube (Y). See Transmission and Hydraulic Oil in Other Lubricants section of this Operator’s Manual.


  33. Do not depress brake pedal during this step. If brake pedal is depressed, additional oil flows to axles and result in an inaccurate oil level check.

    Place transmission in PARK.

    1. Start Engine

    2. Run engine at 1200 rpm for 5 minutes.

  34. Shut engine OFF and wait 5 minutes for oil level to stabilize.

  35. Confirm that oil level will not fall too low if tractor is to be used with implements with large hydraulic cylinders that remove large volumes of oil from the hydraulic system. Place implement in position that requires maximum amount of oil. Oil level should be near High Volume Takeout Oil Mark position on sight gauge.

    Check to ensure transmission-hydraulic reservoir oil level is visible between Min Cold and Full Cold marks in the sight gauge. If oil level is visible between Min Cold and Full Cold, tractor can be used for normal operation. Oil level in reservoir will rise as temperature increases. Replace the transmission-hydraulic oil reservoir vent filter. See Transmission-Hydraulic Vent Filter in this Operator’s Manual section.

  36. Volume capacity between Min Cold mark and Full Cold mark is 11.4 L (3 gal).

    If oil level is below Min Cold is sight gauge, add oil through reservoir cap.

  37. Excess hydraulic oil can result in decreased engine power and decrease fuel economy.

    If oil level is above Full Cold mark, remove enough oil to bring it down to Full Cold mark level.

    Remove drain plug under hydraulic oil reservoir and direct oil into a container.
