LUBRICATION RECOMMENDATIONS
IMPORTANT: POWER WHEEL PLANETARY 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 Power Wheel 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 plug located in cover. Oil 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 F (93 C) contact Auburn Gear for oil and level recommendations.
TOWING VEHICLE
CAUTION: The Power Wheel will not normally be damaged by towing; however, the hydraulic drive components may be damaged unless the Power Wheel
is disengaged from the drive motor. Road speeds in excess of 25 MPH should be avoided unless clearly specified to be permissible by the equipment
manufacturer.
TO DISENGAGE POWER WHEEL
CAUTION: For units equipped with the standard spring disconnect, assemble the disengage cover (30) with the dimpled center protruding inward. For units
equipped with the optional quick disconnect, push in center plunger of disconnect.
STORAGE
A protective film is applied to the Power Wheel at the factory to prevent rust during shipment. Additional protection may be required if the Power Wheel is
to be stored for an extended period of time.
SEALING COMPOUND
Silastic RTV 732 sealer and General Electric Silimate RTV No. 1473 or RTV No. 1503 are currently recommended for sealing gasket surfaces. Sealant should
be applied in a continuous bead, which should be centered on the surface to be sealed but should move to the inside of the hole at each bolt hole location.
For service requirements order Auburn Gear Part number 604101.
