IMPORTANT: Carefully follow drain and fill procedure to prevent premature transmission/axle failure.

NOTE: Calibrate transmission if shift characteristics change after system oil and filter change. See Transmission Calibration in General Service section of this Operator’s Manual.

The transmission, hydraulic reservoir and rear axle are all included in the hydraulic system. Change all hydraulic filters at this interval. See all filter changes in this section.

An oil drain container with a maximum capacity of 310.9 L (82.1 gal) should be used.

1. Park tractor on level surface with drain plugs on each wheel hub oriented downward.

2. Allow hydraulic oil to cool for 15 minutes.

   NOTE: Full system oil capacity is 310.9 L (82.1 gal). Secure drain pan of sufficient capacity.

3. Remove drain plug (A), located under hydraulic reservoir, to drain oil from reservoir.

4. Remove Powershift transmission drain plug (B).

5. Remove three rear axle drain plugs (C).

   Item	Measurement	Specification
   Transmission Drain Plugs	Torque	55 N·m (40 lb-ft)
   Rear Axle and Outboard Planetary Drain Plugs	Torque	70 N·m (52 lb-ft)

8. IMPORTANT: When oil is drained from the transmission for a scheduled oil change, the transmission will need to be pre-filled with 38 L (10 gal) of Hy-Gard™ (JDM J20C) oil ONLY or damage could occur to transmission when the tractor is started.

   To ensure proper shift quality, oil meeting Hy-Gard™ or JDM J20C specifications must be used. Shift quality problems and/or transmission damage may occur if the specifications are not followed. See Transmission/Axle and Hydraulic Oil in Fuel, Lubricants and Coolant section of this Operator’s Manual.

    NOTE: Clean the hydraulic oil system vent filter, at rear of cab. See CLEAN HYDRAULIC OIL SYSTEM VENT FILTER in this Section.

    The volume capacity between Min “Cold” (C) and Full “Cold” (B) marks is 11.4 L (3 gal).

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

35. Follow oil check procedure for correct oil level.

    OIL LEVEL CHECK PROCEDURE:

    1. IMPORTANT: DO NOT start engine if oil level is below MIN COLD mark (C). Add Hy-Gard JDM J20C hydraulic oil using hydraulic reservoir fill cap.

       Transmission lever should be in PARK.
    2. Start engine and idle at 1200 rpm for 5 minutes.
    3. Shut engine OFF and wait 5 minutes for oil level to stabilize.
    4. Check to ensure transmission/hydraulic/axle oil level is visible between “Full Cold” (B) and “Min Cold” (C) marks in sight gauge.
    
    

    NOTE: Hydraulic oil reservoir does not hold all system hydraulic oil capacity. If possible check oil level before first start of day. Ambient temperature should be 7° C. (45° F) or above.

    For applications and implements requiring high volumes of oil transfer (for example - large air seeders or pulling 3 scrapers), hydraulic reservoir can be filled up to High Oil Volume Takeout Oil Mark (D). 126.4 L (33.4 gal) above MIN COLD (C).

    As the tractor and hydraulic system get hot, the oil level will rise (increase) in the reservoir.

    Oil level in the reservoir will fluctuate depending upon volume of oil exchanged with an attached implement. The pressure sensor will send alert if pressure falls too low due to low oil level.

    NOTE: The powershift transmission only needs to be recalibrated if transmission shift characteristics change after hydraulic/transmission/axle oil and filters are changed. See Powershift Transmission Calibration in General Maintenance and Inspection Section.

36. IMPORTANT: Excess hydraulic oil can result in decreased engine power and decrease fuel economy.

    If oil level is above the “Full Cold” mark, remove oil to bring it down to the “Full Cold" mark level.

    The recommended method to remove reservoir oil is using the reservoir drain plug and direct oil into a container.
