1. On operator side of chute, find pulley center point (A).
2. Measure radius of head pulley including lagging and belt thickness (B).
To this dimension, add 3.50 in. (89 mm).
3. Starting from center point (A), measure the total distance calculated in
step 2 (B + 3.50) and draw an arc on chute wall.
4. Measure down from pulley's horizontal centerline the distance shown in
Figure 3 and draw a horizontal line parallel to it. Locate center point of
belt cleaner mainframe (C) where this line intersects the arc on the chute
wall.
5. Make sure mainframe and blade do not lie in path of material unloading
from conveyor belt.
6. Repeat steps 1 through 5 for far side chute wall.
7. Drill or cut holes for tensioner mounting plates on chute walls as follows:
a. If bolting tensioner mounting plates to chute walls, do the following:
(1) Drill or cut one 4-in. hole for mainframe and four 5/8-in. holes for
screws in both operator side and far side chute walls. Remove
burrs and sharp edges.
b. If welding tensioner mounting plates to chute walls, do the following:
(1) Drill or cut one 4-in. hole for mainframe in both operator side and
far side chute walls. Remove burrs and sharp edges.
8. If using Martin
