Maintenance   27 

 

NOTE:

 

You must  take the chain off the drive motor sprocket or the 

conveyor will not move freely. You must be able to move the 

conveyor to replace silicone covering on the rollers. 

 

3.  Remove old covering, by carefully slitting the covering and then pulling it off. 

 

4.  Clean all rollers using steel  wool or a wire wheel. Make sure all rollers are 

smooth and free of residue and burrs. 

 

5.  Fit the new silicone rubber tubing onto each roller and work on by hand at least 

½ inch. At the opposite end of the tubing, fit on and secure an air supply hose of 

low pressure, maximum pressure 5 lbs. While tubing is slightly expanded by air 

pressure, push the tubing onto the roller and work it on to the roller. Be careful to 

hold the roller at all time so it does not fly from the air pressure. 

 

6.  Replace rollers on conveyor by inserting roller end holes into the extended pins 

of the chain. Reconnect drive chain around drive motor sprocket. Adjust tension 

on drive chain by retightening the four (4) bolts. Place access-hole cover back 

on, and replace idler end caps. 

 

7.  Check conveyor chain tension by following the steps explained earlier. 

 

Idler, roller shaft, bearings, or sprockets replacement 

Refer to the Roller Silicone Covering Replacement section above to access and remove 

rollers as required. Note the location and orientation of sprockets (make a sketch and 

note measurements if necessary). Loosen the jam nuts on the tensioning bolts at the 

drive end of the conveyor. Remove the four (4) ¼-20 bolts for the bearings. Slide the 

shaft left or right and then the shaft and sprockets will come off. Identify and replace any 

damaged or worn parts and reassemble in reverse order of disassembly. 

 

Drive shaft, bearings, or sprockets replacement 

Refer to the Conveyor belt tension adjustment section above to open up the conveyor 

belt. Remove the drive end caps. Disconnect the conveyor belt. Note the location and 

orientation of sprockets (make a sketch and note measurements if necessary). Loosen 

four (4) set screws on the drive sprockets. Keep the keyway key for the driveshaft and 

replace as necessary. Slide the shaft left or right. The shaft sprockets must be adjusted 

for position. All sprockets are fastened to the shaft by set screws. Identify and replace 

any damaged or worn parts and reassemble in reverse order of disassembly. 

 

Conveyor motor replacement 

Shut off the machine and disconnect main power. Remove the drive end cap, 

disconnect two (2) electrical wires from the drive motor, and disconnect the motor from 

the drive chain by removing four (4) bolts that hold the drive motor. Remove the 

sprocket from the old motor and place it on the new drive motor and reassemble parts in 

the same as they were disassembled. For electrical connections, refer to the electrical 

schematics.
