4.6.2 Removing Chain Links

Turn off power and Lockout/Tagout all power to the conveyor before starting drive
chain and driver pad maintenance. Failure to follow these instructions may result in
serious personal injury.
When the chain take-up is at the end of the travel, it is necessary to remove some
chain links to allow the take-up sprocket to be retracted.
Use the following procedure for removing chain links.
1. Remove sufficient carrier rollers in the tail end section to access the chain from top of
the conveyor.
Note: Connector links are typically installed within 12 inches (300 mm) of the driver
pad splice.
2. Jog the conveyor until the connector link is located in the open area immediately
adjacent to the tail end take-up sprocket.
3. Adjust the take-up to fully retract the sprocket.
Starting at the splice, lift the driver pad from the chain's extended pins to expose the
4.
connecting link.
Remove the chain's spring clip, connecting plate, and connecting link. Pull the
5.
excess slack out of the chain and determine the number of links to remove. See the
illustration in this topic.
6. Using a chain breaker tool, remove the necessary links. One link is defined as being
the center distance (1.25 inches) between two extended pins.
7. Record the number of chain links removed. This information is needed to determine
when the chain is over 2% elongated and must be replaced. See topic Maximum
Chain Elongation Limit in this chapter to determine when the chain is over 2%
elongated.
