The left and right frames (Nos. 85 and 87) are screwed to the side cover. The front frame
( No. 205) is screwed to a bracket on the reclaim chamber. After removing the magnetic
frame, on the rear side of the opening is the retaining plate for the backskirt (No. 197). The
back skirt, mentioned in chapter 3.7, is screwed to this part.
Wear & tear happens mainly to this part if it is in contact with the floor. As previously
mentioned, it is important to check all parts regularly. In doing so, it is not necessary to
unscrew the magnetic frame, just place the machine carefully on it's side and check for
wear & tear.
Bearings
3.9
Bearings are always a sensitive issue in mechanical engineering. Changing bearings pro-
perly is actually not difficult if basic rules are followed. Describing these rules is beyond
the scope of this manual. If you have any doubts always refer to trained or experienced
engineer.
In the shot blaster Shotblaster machine, bearings are located in the motors, the drive unit
lever, are
situated in the motors, the drive unit lever, the turbine axle housing, the drive unit frame
and the wheels. Never attempt to change the motor bearings by yourself. Send the motors
back to the factory or take them to an a reputable motor rewind technician.
The turbine axle housing is the most difficult item to deal with. The bearings inside are un-
der the greatest stress from the operation of the machine. The lifetime of such high speed
revolving bearings is between 500 and 1000 hours. To change the bearings send the ma-
chine or machine housing to CONTEC / TYROLIT.
