SECTION 4
– INSTALLATION
Lower Belt Tracker
Locate the lower guide unit approximately three times the belt width
before the point where the belt adjustment is needed or before any major pulley. If installing
multiple units, allow 21 to 50m between units depending on the severity of mistracking.
Upper Belt Tracker
Locate the upper guide unit beyond the loading point or three times
the belt width before the point where the belt adjustment is needed. If installing multiple units,
allow 21 to 50m between units depending on the severity of mistracking.
Remove existing troughing idler. Set aside for later use.
Step 1.
Refer to the installation drawing F0154 (lower) or F0155 (upper) attached.
Mark out the four hole patterns at 300mm centres on the stringers as shown.
Check before drilling the hole patterns are perpendicular to each other from the left to right
stringers.
If measuring from the tail pulley, first ensure the tail pulley is square with the stringers.
Step 2.
Refer to the exploded parts drawing F0158 (lower) or F0159 (upper) attached.
Install the rear cross section. Mounts should be fastened after the rear cross section is in place.
Step 3.
Fit the cross section/pivot plate into position using the M12 x 210 lg. bolt & nyloc nut.
Tighten the nut & check that the cross section pivots freely.
Step 4.
Adjust both the rear cross section and cross section/pivot plate.
Ensuring that they are both centralised and the cross section/pivot plate is adjusted correctly for
the Idler (client supply), tighten the adjustment screws.
Step 5.
Adjust the rear cross section to engage the training idler to the belt. The idler should be elevated
20-25mm from the standard return idler alignment as shown on the installation drawing.
Step 6.
Install the front cross section.
Mounts should be fastened after the front cross section is in place. Adjust the front cross section,
ensuring the torque arm pivot point is aligned centrally with the cross section/pivot plate pivot
point.
Fit the torque arm using the M12 x 175 lg. bolt & nyloc nut. Tighten the nut and ensure the torque
arm pivots freely.
Step 7.
Fit the guide frame (without guide arms) to the torque arm using the M12 x 135 lg. bolt & nyloc
nut. Tighten the nut and ensure the guide frame pivots freely.
Step 8.
Fit the parallel stay to the guide frame and front cross section using an M12 nyloc nut.
Adjust the parallel stay if required to ensure the guide frame is parallel with the front cross section
and perpendicular with the torque arm when the unit is centralised.
