1 - Machines without Grease Nipples
Motors up to frame 324/6T are normally fitted without grease
nipples. In these cases the regreasing shall be done at the
preventive maintenance job observing the following aspects:
9
Disassemble carefully the motors.
9
Take all the grease out.
9
Wash the bearing with querosene or diesel.
9
Regrease the bearing immediately.
2 - Machines Fitted with Grease Nipples
It is strongly recommended to grease the machine while
running. This allows the grease renewal in the bearing housing.
When this is not possible due to turning parts by the grease
device (pulleys, bushing, etc) that offer some risk to the
physical integrity of the operator, proceed as follows:
9
Clean the area near to the grease nipple.
9
Put approximately half of the total grease and run the motor
for 1 minute at full speed. Then turn off the motor and pump
the rest of the grease.
9
The injection of all the grease with the motor in standstill
can make the grease penetrate into the motor, through the
inner seal of the bearing housing.
When regreasing, use only special bearing grease with the
following properties:
LUBRICATION
FOLLOW THE REGREASING INTERVALS. THIS IS
FUNDAMENTAL FOR PROPER MOTOR
OPERATION.
