DRIVE PULLEY – CARRY THROUGH BELT
The drive shafts drive two belts, the compression belts and the carry through belts. The drive
pulley for the carry through belt is attached to the bottom of the shaft. Occasionally check the
screws, which hold the pulley to the compression drive sprocket. At the factory the screw threads
are treated with Loctite
®
222 to prevent them from coming loose. Since the pulleys attach directly
to the compression sprockets, these do not contain bearings. Unless a pulley becomes damaged, it
will not need to be replaced. If the pulley does need to be replaced, follow these steps.
1.
Turn “OFF” and lock out the electrical
and pneumatic supplies.
2. Remove the fixed and swing channel
shrouds.
3. Loosen, but do not remove, the four top
