8.14 Replacing the Conveyer Belts
Checking the condition of the conveyor belts should be part of the routine maintenance schedule for the
dispensing system. Cracked, worn, or broken belts should be replaced immediately.
To maintain reliable system performance, it is recommended that the conveyor belts be changed every six
months. However, the belts may need to be changed more frequently or less frequently, de
pending on the
volume of workpiece production.
Tools and Materials Needed:
• Hex Key Set (Item 59)
• Soft Cloth and Cotton Swabs
• Torque Wrench
• Replacement Conveyor Belts
• Isopropyl Alcohol
• Removable Thread Locker 242
• Phillips Head Screwdriver
(Item 59)
WARNING! Ensure the dispensing system has been completely shutdown before attempting to
remove or install any panel, electrical component, or pneumatic component.
WARNING! This procedure should only be performed by a trained service technician.
NOTE Only one belt should be removed at a time. Use the other belt as a reference for proper
orientation of the belt being replaced.
To remove a conveyor belt (Figure 8-19):
1. Use the Fluidmove Jog Controls to move the dispense head to the back of the machine.
Refer to the Fluidmove User Guide or Fluidmove Online Help.
2. Use the Fluidmove Jog Controls to move the rear conveyor rail as needed. Refer to the
Fluidmove User Guide or Fluidmove Online Help.
3. Perf
orm a service shutdown, see 2.14 Service Shutdown.
4. Open the dispensing area door.
5. Remove any rail-mounted components that interfere with belt removal/replacement.
If stop pins interfere, use a 2.5 mm hex key to remove the stop pins along the length of
the conveyor rails.
NOTE For ease of reinstallation, you should note the locations and orientations of the
rail-mounted components before removing them.
6. Loosen the pulley screws at each end of the conveyor and move the pulleys to
the right or
left to loosen the belt.
7. Slide the old conveyor belt off the pulleys and discard.
