4. Alignment:
a. Conveyor belts: They are properly aligned
when the belt runs in the center of the frame
panels and the shafts. Be sure to run the con-
veyor a full revolution to check the entire belt.
the belt can move from side-to-side while it is
turning as long as it doesn't contact the sides.
If it contacts the sides, it must be aligned.
Align by loosening the shaft bearing assembly
on the tight side or tightening the bearing as-
sembly on the loose side. Move the bearing
assemblies on either the drive or driven shafts
to align the conveyor but always maintain the
proper tension.
b. Conveyor chain: They are properly aligned
when the chain links center on the drive
sprockets. If the links run on the side of the
sprockets, align the chain. Align by loosening
the shaft bearing assembly on the tight side or
tightening the bearing assembly on the loose
side. Move the bearing assemblies on either
the drive or driven shafts but always maintain
the proper tension.
5. Replacement:
a. Move one or both of the shafts into their loos-
est position.
b. Open the conveyor by splitting the links on the
chain type or removing the connecting rod on
the belt type.
c. Attach the replacement conveyor to the end of
the old conveyor belt/chain.
d. Slowly pull the old conveyor out of the ma-
chine and thread the new one into position.
e. Disconnect the old conveyor and connect the
ends of the new one together.
f. Move the shaft into position to set the ten-
sion of the conveyor and secure the bearing
assemblies.

g. Check the tension and alignment of the con-
veyor frequently during the rst 10 hours of
operation and set as required. Then, go to
the regular maintenance schedule. Normally
a conveyor will seat itself during the rst 10
hours of operation and then require less
adjustment.
