• Stalling or slipping
Surface cuts and wear indicate:
• Sharp or heavy parts impacting belt
• Jammed parts
• Improperly installed bottom wiper
• Accumulated dirt in wiper
• Foreign material inside the conveyor

• Conveyor belt or drive timing belt are not properly ten-
sioned
• Worn knurl or impacted dirt on drive pulley
• Intermittent jamming or drive train problems
Cleaning
Use Dorner Belt Cleaner (part number 625619). Mild soap
and water may also be used. Do not soak the belt.
For /05 woven polyester and /06 black anti-static belts, use a
bristled brush to improve cleaning.
A
WARNING

injury.
LOCK OUT POWER before removing guards
or performing maintenance.
IMPORTANT
Do not use belt cleaners that contain alcohol,
acetone, Methyl Ethyl Ketone (MEK) or other
harsh chemicals.

V-Guided Belts
V-guided belts do not require tracking adjustment.
Non V-Guided Belts
Non V-guided belt conveyors are equipped with belt tracking
cam assemblies (Figure 45, item 1) for belt tracking
adjustment.
Figure 45
Figure 45
When adjusting belt tracking, always adjust the discharge
end of the conveyor first. To adjust belt tracking:
1. Ensure head plate fastening screws (Figure 45, item 2)
on both sides of conveyor are tightened.
2. On both sides of conveyor, loosen two (2) cam fastening
screws (Figure 45, item 3). Adjust cams (Figure
45, item 4) until indicator slots (Figure 45, item 5) are
horizontal and facing end of conveyor. Then slide cam
assemblies against head plates (Figure 45, item 6) and
re-tighten cam fastening screws (Figure 45, item 3) to
60 in-lb (7 Nm).
3. On the side toward which the belt is tracking, loosen
head plate fastening screws (Figure 45, item 2).
4. With the conveyor running, use a 5 mm hex-key wrench
to rotate the tracking cam (Figure 45, item 4) in small
increments until the belt tracks in the center of the
conveyor. Then while holding the cam in position, re-
tighten the head plate fastening screws (Figure
45, item 2) with a 4 mm hex-key wrench to 60 in-lb (7
Nm).
