5000/10000 FLYWHEEL GRINDER
GRINDING MOTOR
CAUTION: Overgreasing bearings can cause premature bearing and/or motor failure. The
amount of grease added should be carefully controlled.
NOTE: If lubrication instructions are shown on the motor nameplate, they will supersede this
general instruction.
Motors are pregreased with a polyurea mineral oil NGLI grade 2 type grease unless stated
otherwise on the motor nameplate. Some compatible brands of polyurea mineral base type
grease are: Chevron SRI#2, Rykon Premium #2, Shell Oil Dolium R or Texaco Polystar RB.
Motors may be greased at 500 hour intervals, adding .30 oz. of recommended grease to each
bearing.
POWER COLUMN GEARMOTOR
The power column gearmotor is a permanently sealed unit and does not require any further
lubrication.

1. INTIAL OIL CHANGE: The oil in a new speed reducer should be changed at 250 hours of
operation.
2. SUBSEQUENT OIL CHANGES: Under normal conditions, after the initial oil change, the oil
should be changed after every 2,500 hours of operation, or every six months, whichever
occurs first. Under severe conditions (rapid temperature changes, moist, dirty, or corrosive
environment) it may be necessary to change oil at intervals of one to three months. Periodic
examination of oil samples taken from the unit will help establish the appropriate interval.
3. OVERFILLING OR UNDERFILLING: If a speed reducer is overfilled with oil, the energy
used in churning the excessive oil can result in overheating. If this occurs, shut down the
drive, remove the oil level plug and allow oil to drain until oil ceases to drain from the level
hole. reinstall the oil level plug, and restart the drive. If the speed reducer is underfilled, the
resultant friction can cause overheating and possible damage. If this occurs, fill the speed
reducer to the oil level plug hole and check the gearing for excessive wear.
