Transmission and Hydraulic Oil

LV1939-UN-02MAY97

Depending upon the expected air temperature range during the drain interval, use oil viscosity shown on the adjoining temperature chart.

John Deere HY-GARD® Transmission/Hydraulic Oil is recommended. HY-GARD oil is specially formulated to minimize wet brake chatter and to provide maximum protection against mechanical wear, corrosion, and foaming.

Other oils may be used if they meet John Deere Standard JDM J20C or J20D.

Oils meeting Military Specifications MIL-L46167A may be used as arctic oils for temperatures below -40°C (-40°F).

For operation below -25°C (-13°F), use of J20D oil is required to protect hydraulic system. Be sure to drain and refill system with a regular viscosity oil at temperature indicated on chart. Steering circuit should be drained when changing oils to avoid mixing oils of different viscosities.
