Conveyor Belt Tensioning
Conveyors with 1.25¨ (32 mm) Diameter
Pulleys
1. On tension end of the conveyor, identified with a
label (Figure 26, item 1), adjust head plate
assembly (Figure 26, item 2): On both sides of
conveyor, loosen fastening screws (Figure 26, item 3)
and rotate pinion gear (Figure 26, item 4) to adjust head
plate assembly.
Figure 26
Figure 26
2. Adjust head plate assembly so end of conveyor frame
aligns with or between the head plate tensioning marks
(Figure 27, item 1 & 2). Replace belt if proper
tensioning can not be obtained while aligning the end of
the conveyor frame with or between the tensioning
marks. See NOTE.
Figure 27
Figure 27
3. After adjusting proper tensioning, tighten fastening
screws (Figure 26, item 3) on both sides of conveyor to
60 in-lb (7 Nm).
4. If equipped with cam tracking assemblies (Figure
26, item 5), position against head plates and adjust belt
tracking. Refer to “Conveyor Belt Tracking” on
page 14.
Conveyors with Nose Bar Idlers
1. On tension end of the conveyor, identified with a
label (Figure 28, item 1), adjust head plate
assembly (Figure 28, item 2): On both sides of
conveyor, loosen fastening screws (Figure 28, item 3)
and rotate pinion gear (Figure 28, item 4) to adjust head
plate assembly.
Figure 28
Figure 28
2. Adjust head plate assembly so the edge of the axle
support plate (Figure 29, item 1) is separated from the
end of the conveyor (Figure 29, item 2) by 1.125¨ (29
mm). Replace belt if proper tensioning can not be
obtained within a distance of 1.50¨ (38 mm). See NOTE.
A

5. Ensure head plate fastening screws (Figure 30, item 2)
on both sides of conveyor are tightened.
6. On both sides of conveyor, loosen two (2) cam fastening
screws (Figure 30, item 3). Adjust cams (Figure
30, item 4) until indicator slots (Figure 30, item 5) are
horizontal and facing end of conveyor. Then slide cam
assemblies against head plates (Figure 30, item 6) and
re-tighten cam fastening screws (Figure 30, item 3) to
60 in-lb (7 Nm).
7. On the side toward which the belt is tracking, loosen
head plate fastening screws (Figure 30, item 2).
8. With the conveyor running, use a 5 mm hex-key wrench
to rotate the tracking cam (Figure 30, 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
30, item 2) with a 4 mm hex-key wrench to 60 in-lb (7
Nm).
NOTE
On pinion gear, do not exceed a torque of 25
in-lb (2.8 Nm) for 2 – 12¨ (44 – 305 mm) wide
conveyors or 50 in-lb (4.5 Nm) for an 18 – 24¨
(457 – 610 mm) wide conveyor. Over
tensioning the conveyor belt could cause
excessive pulley bearing load and early
failure.
