Lubrication

All head and tail pulley bearings are pre-greased at the factory. These bearings should be field

greased periodically. Lubrication frequency may vary; dry, dusty applications may warrant

weekly greasing, while less harsh applications may need greasing only once or twice a year. Do

not exceed 10,000 hours of operation between re-greasing.

If there is a gear reducer supplied with your weighfeeder, it has an initial break-in period. After

the first 250 hours of operation, the gear box(es) should be drained and refilled to the proper

level(s). Subsequent oil changes should be done every 2500 hours. See the gear reducer

manual for further details.

If there is a gear motor (motor and reducer all in one housing) supplied with your unit, it is

permanently lubricated. No lubrication is necessary.

8.4

If a weighfeeder will be stored for a period of three months or more, follow the guidelines below.

8.4.1

The load cell shipping bolt(s) should be installed whenever the weighfeeder is moved as an

extra safety measure during the storage period. Do not forget to remove the shipping bolt(s)

upon re-installation.

8.4.2

Uncouple the gear reducer from the weighfeeder drive shaft and the motor and grease all shaft

surfaces liberally with an appropriate lubricant to help with reassembly.

In addition, fill the gear reducer with an appropriate gear oil to prevent oxidation. When the

equipment is re-installed, completely drain this gear oil and then refill the reducer to the

appropriate level.

8.4.3

To prevent oxidation, place a desiccant or moisture removal material in all electrical junction

boxes and component cabinets. This includes the load cell junction box, the integrator cabinet,

and the motor speed controller enclosure (if present).
