SERVICE INTERVAL —

INITIAL — 1500 HOURS

SCHEDULED — 1500 HOURS *

* Intervals can vary according to operating conditions

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

NOTE: The powershift transmission only needs to be recalibrated if transmission shift characteristics change after transmission oil and filter change. See Powershift Transmission Calibration procedure in General Maintenance and Inspection Section.

The transmission, hydraulic reservoir and rear axle are all included in the hydraulic oil system.

Use an oil drain container with a maximum capacity of 293.4 L (77.5 gal), depending on option configuration.

  1. Park tractor on level ground and shut engine OFF. Allow oil to cool for few minutes.

  2. Attach a hose to hydraulic reservoir drain valve (A) in gudgeon area at rear of reservoir. Open drain valve to direct oil into a catch container.

  23. NOTE: Tractors with Double Reduction Axles are vented when oil is circulated to front and rear axles and do not need to perform step 23. Go to step 24 entitled: Perform Following Steps For All Tractors:

    Tractors with Single Reduction Axles, perform steps 23, then step 24 “Perform Following Steps For All Tractors”

    Remove front axle plug (B) and rear axle plug (C) to bleed air from each axle.

    C - Reservoir Fill Cap

    Perform Following Steps For All Tractors:

    NOTE: The hydraulic reservoir will not hold total oil volume for the system until engine is started and oil is circulated to transmission and axles, resulting in a lower reservoir oil level. The reservoir will need to be filled to the correct level.

    NOTE: Clean the hydraulic oil system vent filter while the side panel is removed. See CLEAN HYDRAULIC OIL SYSTEM VENT FILTER in this Section.

    Remove right-hand cab panel retaining screws (A) and remove right-hand cab side panel (B).


  25. Remove reservoir fill cap (C) and add remaining hydraulic oil volume to the reservoir.

    A - “Full Hot” Mark

    B - “Full Cold” Mark

    C - “Min Cold” Mark

    D - “Do Not Start” Mark

    OIL LEVEL CHECK PROCEDURE:

    IMPORTANT: Poor shift quality and/or transmission damage may occur if the HY-GARD or JDM J20C specifications are not followed. To ensure proper shift quality, an oil meeting HY-GARD or JDM J20C specifications must be used.

    Transmission lever should be in PARK.


  28. For Single Reduction Axle Tractors: perform steps 28 and 29. Start and set engine speed at 1200 rpm for approximately 5 minutes or until oil is circulated and appears at both axle ports.

    For Double Reduction Axle Tractors: Go to step 30.

  29. Stop engine and install both axle plugs. Go to step 30.

  30. NOTE: DO NOT step on brake pedal during this segment of the procedure to avoid additional oil flow to the axles and resulting in an inaccurate oil level check.

    Perform For All Tractors:

    Start engine and set engine speed at 1200 rpm for 5 minutes.

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

  32. Add more of remaining oil volume to hydraulic reservoir if oil level drops to Do Not Start (D) mark. Then resume operation of tractor at 1200 rpm per the oil level checking procedure.

  33. Check to ensure transmission/hydraulic reservoir/axle oil level is visible between “Min Cold” (C) and “Full Cold” (B) marks in the sight gauge.

    NOTE: Volume capacity between “Min Cold” mark (C) and “Full Cold” mark (B) is 11.4 L (3 gal).

    Estimate volume of oil that needs to be removed or added.

    If oil level is visible between Min Cold (C) and Full Cold (B), tractor can be used for normal operation.

  34. Identify oil volume required in reservoir until it reaches marks Min Cold (C) or Full Cold (B). If oil level is below (C) in sight gauge, add HY-GARD Hydraulic Oil through reservoir fill cap for 1500 Hour service procedure.

    For daily checks or add oil if sight gauge is below Min Cold (C) mark, but above Do Not Start (D) mark, add required volume of HY-GARD Transmission-Hydraulic Oil using fill tube, at rear of transmission.

    If oil volume required is below Do Not Start mark, add required oil through hydraulic reservoir fill cap, under right-hand cab side panel.

    NOTE: An exception is implements with large hydraulic cylinders that can remove large volumes of oil from the tractor's hydraulic system. Oil level should be near bottom mark of sight gage with implement positioned to contain maximum amount of oil.

    NOTE: Oil level in reservoir will rise as temperature increases.

    Oil level in the reservoir will fluctuate depending upon the volume of oil exchanged with an attached implement.

    If low oil level results in pressure drop, a STOP engine light will come on.

  35. The oil level checking procedure should be repeated and oil level adjusted until oil level stabilizes between Min Cold (C) and Full Cold (B) marks.

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

    Recommended method to remove oil is use drain valve at rear and under the hydraulic reservoir, in hinge area. A hose can be attached to drain valve to direct oil into a container.

  37. Reinstall right-hand cab side panel and tighten using retaining screws.
