Maintaining Conveyor Belt
Troubleshooting
Inspect conveyor belt for:
Surface cuts or wear
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
Improperly positioned accessories
Bolt-on guiding is pinching belt
Stalling or slipping indicates:
Excessive load on belt
Conveyor belt or drive timing belt are not properly
tensioned
Worn knurl or impacted dirt on drive pulley
Intermittent jamming or drive train problems
NOTE: Visit www.dorner.com for complete list of
troubleshooting solutions.
Cleaning
IMPORTANT: Do not use belt cleaners that con-
tain alcohol, acetone, Methyl Ethyl Ketone (MEK) or
other harsh chemicals.
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.

When adjusting belt tracking, always adjust the dis-
charge end of the conveyor first. To adjust belt tracking:
1.Ensure head plate fastening screws (U of Figure 42)
on both sides of conveyor are tightened.
2.On both sides of conveyor, loosen two (2) cam
fastening screws (BU). Adjust cams (BV) until
indicator slots (BW) are horizontal and facing end of
conveyor. Then slide cam assemblies against head
plates (S) and re-tighten cam fastening screws (BU)
to 60 in-lb (7 Nm).
3.On the side toward which the belt is tracking, loosen
head plate fastening screws (U).
4.With the conveyor running, use a 5 mm hex-key
wrench to rotate the tracking cam (BV) 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 (U) with
a 4 mm hex-key wrench to 60 in-lb (7 Nm).
