General Maintenance (cont.)
BEARINGS:
BEARING REPLACEMENT: Spray area with rust penetrant (WD-40). Remove sprocket (See SPROCKET
section on page 17). Remove four bolts from airlock bearing flange (two bolts from shredder bearing flange)
Loosen set screws on bearing hub at each end of agitator shaft. Since all set screws are installed with a
medium grade Loctite, a propane hand torch may be used to assist in removing them. Do not overheat unit,
causing shaft to expand. Using a rubber mallet, drive agitator shaft an inch in one direction, creating a space
between hopper and bearing unit. A bearing puller can then be used to remove the bearing. Eliminate any metal
burrs from shaft with file and install new bearings with felt seals. Use a medium grade Loctite on set screws
before securing bearing to shaft. (Check shaft diameter before ordering bearings; 3/4" or 1")
AGITATOR, AIRLOCK AND SHREDDER BEARINGS are prelubricated, double sealed, self aligning ball bearings.
Lubrication is required at three month intervals of normal running time, or sooner if bearings produce a noise or
become too-hot-to-touch. Relubrication at the grease fittings is done with a lithium base grease conforming to
a NLGI GRADE TWO consistency. The grease should be pumped in slowly until a slight bead forms around the
seals. This bead, in addition to acting as an indicator of adequate lubrication, provides additional protection against
the entry of foreign matter. Important: If a slight bead does not form indicating a failure of lubrication or if bearing
shows signs of wear, replace bearing.
SPEED REDUCER:
If speed reducer malfunctions because of improper oil level or type used, warranty is voided. Your speed
reducer has been filled with Mobil Glygoyle 460 Polyglycol (PAG) lubricant. Consult speed reducer manufacturer's
manual for lubricant replacement intervals.
LUBRICATION: This speed reducer was filled with oil at the factory to operate within -10
O
F to +120
O
F ambient
temperature range. LeCentric units utilize extreme pressure lubricants which protect the teeth in the event of
the oil thinning out due to local temperature rise, or high pressure due to accidental overloads. The reducer is
lubed for life and does not require regular oil changes under normal industrial operating conditions and
environments. Oil changes may be required if the reducers are operated in severe environments (i.e. high or
low temperatures, high altitudes, dusty, caustic, etc.)
LUBRICANT REPLACEMENT: (See Illustration O)
1. Drain: With output shaft of speed reducer facing you, remove
plug (A) with 6mm hex key wrench. Tip reducer and allow unit
to completely drain.
2. Fill with recommended lubricant (use Mobil Glygoyle 460
Polyglycol PAG) through plug (A) opening, using a flexible funnel.
(Make sure speed reducer is level when replacing lubricant.)
3. Replace plug (A).
Caution: Do not mix different oils in the reducer.
Oils should be compatible with Vitron seal material.
Caution: Oil should be changed / checked if reducer
is used in severe environment.
Caution: Oil should be changed every 6,000 hours
or after 2 years.
