LUBRICATION RECOMMENDATIONS
IMPORTANT:
WHEEL DRIVES ARE SHIPPED WITHOUT LUBRICANT AND MUST BE FILLED TO THE PROPER
LEVEL PRIOR TO START UP.
Observe lubrication recommendations given by the original equipment manufacturer. When specific
recommendations are not available, use mild extreme pressure lubricant API-GL-5, No. 80 or 90 when
filling the Wheel Drive under normal temperature ranges between 0 - 120
°
F (-18 to 49
°
C). Power
Wheel is to be half full of oil when unit is mounted level and horizontal. Use drain and fill plugs located
in cover and ring gear. Oil is to be changed after first 50 hours of operation with subsequent changes
every 1000 hours or yearly, which ever comes first. If unit is to be operated vertically, if ambient
conditions are outside the specified range, or if the oil temperature exceeds 200
°
