10.8 Replacing Conveyor Chains (C-740)
Checking the condition of the conveyor chains should be part of the routine maintenance schedule for the
dispensing system. Worn or broken chains should be replaced immediately. Refer to Appendix C for an
illustrated parts list of conveyor components.
Tools and Materials Needed:
 Pliers  Phillips Head Screwdriver
 3/32-inch Hex Key  Removable Thread Locker (P/N 40-0019)
 Isopropyl Alcohol  Roller Chain, #25, NP (P/N 193721)
 Soft Cloth and Cotton Swabs  Master Link, #25 Chain (P/N 193722)
To replace the conveyor chains:
1. Perform a service shutdown as described in 6.9.2.4 Service Shutdown.
2. Move the dispensing head to the rear of the machine.
3. Use the manual width adjust to move the rear conveyor rail to achieve an approximate eight-
inch space between the front and rear conveyor rails.
4. Create slack in the chain by loosening the four mounting screws on the back of the motor
bracket and moving the bracket up and down until the desired slack is achieved (
10HFigure 10-2).
