4.7.2 Installing the Belt
1. Place the new belt in between the side frames. Make sure the belt will rotate in the
direction shown by the arrow on the belt, (See section 2.2 for machine’s proper
running direction).
2. Replace the following items by reversing the disassembly procedures. We suggest
that you do so in the following order. Replace the Upper connecting rod Item #314,
Front bearing plate Item #714, Rear bearing plate Item #711, Upper drive cylinder
Item #316, Front idle cylinder Item #317, and the Lower tension cylinder Item #318.
3. Tighten the belt using the lower tension screws, (Item #103, Drawing 5.1.1), Making
the same number of turns for each screw on each side of the machine. Do not over
tighten the belt.
4. Again by reversing the disassembly procedures, replace the following referring to the
appropriate section; The Lower adjustable sheeting roller and third sheeting roller
(Section 4.6), The Rear chamber assembly, Timing belt and Timing pulleys (Section
4.5), The Motor (Section 4.4), and The V-belt (Section 4.3).
NOTE
TIMING PULLEYS MUST BE IN LINE WITH EACH OTHER FOR PROPER
MACHINE OPERATION.
5. Restart the machine. With the machine running, brake the belt with your hand to
check that it does not slip. If the belt slips tighten the tensions screws a few more
turns equally on each side of the machine. If the belt starts to travel to the left or
right, tighten the tension screw on the side the belt is traveling towards. Once the
belt does not travel to the left or right, complete the setting of the belt tension by
giving each tension screw a final 1/4 turn. Remember to not over tighten the belt.
6. Replace the left and right belt guides Items #708 and #709 along with the four
bearings (revolving washers) Item #245 located underneath the belt guides.
7. Replace the heavy belt Item #808.
