3.Disassemble and clean the drive and idler shafts using the following procedure.
a.Loosen (DO NOT REMOVE) the set screw on the outer drive sprocket. Then, slide the drive sprocket off the end of the drive shaft. See Figure
b.Loosen (DO NOT REMOVE) the set screws on all four steel spacers (2 per shaft), AND on all twelve conveyor belt sprockets (6 per shaft).
c.Gently work the shaft sections out of the conveyor frame, removing the conveyor belt sprockets as necessary. See Figures
d.Slide the two sections of each shaft apart.
e.Clean all of the shaft components thoroughly using a rag. Then, lubricate each solid inner shaft, AND the interiors of each hollow shaft, using an
f.Slide the hollow shaft sections over the solid inner shafts. Check that the hollow section that has a drive sprocket attached is placed at the end of the the drive shaft.
g.Slide the reassembled shafts into the conveyor frame. As the shafts are replaced, slide the steel spacers and conveyor belt sprockets onto the shafts. Refer to Figures
h.After the shafts are properly aligned, position the steel spacers against the ends of the bushings on the conveyor frame. Tighten the set screws on the spacers to hold them in place. Leave the conveyor belt sprockets loose at this time.
i.Replace the outer drive sprocket. Tighten its set screw to hold it in place.
j.Refer to Part D, Conveyor Installation, in the Instal- lation section of this Manual to replace the con- veyor belt. As you replace the belt, position the conveyor belt sprockets.
k.After the belt is in place and the sprockets are correctly positioned, tighten the set screws to hold the sprockets in place.
