UBRICATION
The tail take-up rods, nuts, and washers used to tighten the belt must be well
lubricated with oil.
Figure 5.18 show the rods, nuts, and washer areas that must be lubricated.
These areas are not lubricated at the factory and must be lubricated during
installation. Motor oil (30W, 40W, or similar) should be used to lubricate these
areas. DO NOT use spray on lubricants!
1. Lubricate the nut and washer areas.
2. Turn the rods in and out so the oil coats the threads in the nuts and rod.
3. Lubricate entire rod. The washer area must be lubricated with oil.
4. Lubricate the nuts and rods of the leveling rods. These rods are only used to
level the tail section.

ROCEDURE
Important:
Conveyor belt tension and tracking alignment must be checked weekly; more
often with seasonal weather changes.
• The belt must be properly tensioned after the splice and splice protectors /
wiper cleats have been installed. Please follow the belt tension procedure in
Figure 5.19.
• The belt is tightened with the take-up rods
that are located on the centerline of the tail
pulley. Adjust these rods evenly to prevent
misalignment of the tail pulley. Belt tension
is very important for the proper operation
of a Hi Roller Conveyor.
