5.4.13. Rotor Drive Bearing Cartridge – Checking
The condition of the rotor drive bearings should be checked by:
1. Remove the drive belt and rotate the pulley by hand. If a bearing develops a rough
spot or is difficult to rotate, replace the complete bearing cartridge (see Section 6.3.
on page 75). The bearings in the cartridge are not replaceable.
The machine generates heat through the action of the rotors. This
heat is carried out of the machine in the exhaust air. Do not touch or
service until after operation when rotor and exhaust surfaces have
been allowed to cool. Failure to follow these instructions may result
in burns.
2. When a noise is heard in one of the rotors themselves, it probably means the
bearing cartridge needs replacement. Do not run the machine in this condition, as it
will affect the mechanical integrity of the rotors.
Never modify the rotors in any way. They are computer-balanced to
operate at this high speed and modifications could adversely affect it.
Any damaged rotor should be replaced immediately by your dealer.
Do not operate GrainVac in excess of 1000 rpm. Failure to follow
these instructions may result in machine component damage or
failure.
5.4.14. Main Drive Shaft Bearings – Lubrication
1. Lubricate the front bearing on the main drive shaft (see Figure 5.19).
