3.2.2 Lubrication of Gearbox
The 350 KPM gearbox contains two treaded plugs. The two plugs are
magnetic and are removed for oil draining and filling. The magnetic plugs
attract metallic particles, in the lubricating oil.
The oil level in the gearbox should be checked before centrifuge operation.
Remove inspection plate on side of gearbox (See Figure 10b). Oil level is
checked with the plugs are 64° of vertical (See Figure 10a).
Angle is correct when plug is centered on a line between the two inspection
palte hold down screw holes. Normal oil level is indicated by oil at bottom
edge of hole. After initial centrifuge operation the oil level should be checked
weekly or whenever bearings are greased. The magnetic drain plugs should
also be checked and metallic particles removed.
