PLANETARY NOTES

LUBRICATION
• The first oil change should be made after approximately 50-100 working hours. Before filling the gear case again, flush
it with a fluid recommended for this purpose by the lubricant manufacturer. The oil should be changed when warm to
prevent build up of sludge deposits. In cases of a heavy duty cycle (high loads, shocks, harsh environment) even shorter
intervals should be kept between changes. Contact the manufacturer for more information.
• It is advisable to check the oil level at least once per month. If more than 10% of total oil capacity has to be added, then
check for oil leaks. Do not mix oils of different types For wide temperature ranges, synthetic lubricants are recommend-
ed with EP additive (minimum viscosity index of 165, viscosity class VG 150 or VG320). Never mix mineral and synthetic
oils. Failure to comply with these recommendations may result in premature wear and/or failure of the gear reducer or
its components.
MAINTENANCE
• Periodically check to see that the bolts are properly torqued and the plugs (breather, sight, magnetic, and plain) are seated.
While checking the breather, also make sure that it is free from debris. If necessary, remove the breather and flush it out
with a cleaning solvent. Check the magnetic plugs and clean on a regular basis (normally performed during oil changes).
Under normal operation of the gear reducer, the magnetic plugs will collect very fine particulates especially during the
initial break-in period. If you should notice heavy deposits, contact the manufacturer or supplier.
• It is also advisable to make sure the gear reducer maintains proper alignment with the components directly involved with
its operation. If the machine is stopped for a long period (two months or longer), it is necessary to rotate the input every
couple weeks to lubricate the gears and bearings to protect them from corrosion. For longer periods out of service, the
gear case should be completely filled with oil.
OIL SPECIFICATION
• Oil Type: Any oil, which meets EP (Extreme Pressure) Gear Lubricant Specification. EP 80 to 90 WT gear lube, Viscosity
Index of 93 and a viscosity of 780 @ 100°F SUS and 76.7 @ 210° F SUS is recommended. Unit is filled with Mobil SHC629
synthetic at the factory.
• Oil Change: After initial 50 hours, thereafter every 1200 hours or 6 months, which ever comes first. These intervals may
be modified depending on the actual operatinig conditions. If used on seasonal equipment, it is recommended that the
oil be changed at the end of each season to remove moisture and corrosive contaminants.
• Oil Fill Level: Unit should be filled so that oil is visible in the sight gage mounted on the side, approximately half way
up. If there is no sight gage the unit should be filled approximately half full, which can be checked by taking out the
plug located on the side of the planetary, and filling until oil comes out.
