Adjusting the Walking Belt
Belt Tension
Adjust the walk belt tension:
•
whenever the belt slips or moves unsteadily during operation.
•
after installing a new walk belt.
•
each time you remove or replace the walk belt or deck.
Two adjustment methods are specified. Method 1 is preferred, but two
belt tension calipers are required.
♦
Both adjustment screws must be completely slack before starting this
procedure.
Method 1: Using Calipers
1. Turn both tension adjustment screws clockwise until most of the slack
is removed from the belt.
♦
Do not stretch the walk belt at this point.
2. Position one caliper on each side of the belt, approximately 18 inches
from the rear roller assembly.
3. Grasp the belt with one caliper clamp.
4. Pull the slack out of the belt with your fingers, then grasp the belt
with the second clamp.
5. Repeat steps 3 and 4 on the other side of the belt using the other
caliper.
6. Set the dials of both calipers to zero.
7. Alternately tighten each tension adjustment screw in 0.1% increments
until both sides read 0.4%. Be sure that the pointer is exactly on the
line increment of the dial for each setting.
Caution!
Do not overtighten the adjustment screws. Overtightening
can damage the walk belt and roller assemblies.
8. Remove both gauges.
9. Adjust the walk belt tracking.
Method 2: Without Calipers
♦
Both adjustment screws must be completely slack before starting this
procedure.
Use this method only if two belt tension calipers are not available. An
accurate measuring device is required.
1. Turn both tension adjustment screws clockwise until most of the slack
is removed from the belt.
♦
Do not stretch the walk belt at this point.
2. Place two pieces of masking tape or two light pencil marks on the
right edge of the belt exactly 50.000 inches apart.
