Contact Roller Reinstallation
To reinstall the contact roller complete the
following steps:
1. Clean the roller shafts with a solvent such as
rubbing alcohol or paint thinner.
2. Clean the inside of the bearing’s set screw
holes with solvent.
3. Slide the left and right bearings onto the shaft.
4. Install contact roller and bolts starting from
right to left.
5. Adjust the contact roller so it measures 2”
from the right side wall to the end of the
rubber. See Fig. 71. Apply a few drops of
Loc Tite to each set screw of the shaft.
Re-leveling The Contact Roller
It is recommended to use a dial indicator to level
the roller. If a dial indicator is not available you
can use a steel ruler.
To level the contact roller use the same size metal
spacers, as shown in Fig. 70, and complete the
following steps:
1. Place the metal spacers under the roller, on top
of the table. See Fig. 70.
NOTE: You may also need to roll back the side
of the conveyor belt to expose the steel table by
loosening the tensioning bolts and then
wrapping something around the belts and
pulling tight.
2. Slide the bars under the roller and compare the
friction from the right to the left.
3. Loosen the bearing bolts. Slide the roller up or
down until it is parallel with the conveyor
table.
4. Re-tighten bolts.
5. Reinstall the drive pulley and side cover.
