Replacement of worn parts – conveyor chain
Removal of conveyor chain
1 Ensure that the power to the drive motor is discon-
nected.
2 Disengage the motor; there are various methods
depending on the type of drive unit:
— Detach the slip clutch.
— Remove the roller chain.
— Disengage the gear from the drive wheel.
3 Split the chain by removing the steel pin from the
pivot. Use the special tool for insertion/removal.
4 Pull out the chain.
Fitting the conveyor chain
1 Run a sample (approx. 0.3 m) of conveyor chain
through the installation in the direction of the con-
veyor. Check that the chain moves easily and cor-
rectly through the bends and idler ends. Check at the
same time that there is enough space for the chain.
2 Put the new conveyor chain in place. Check that the
chain direction corresponds to the conveyor direction.
Note
Be careful that the first link of the conveyor chain does
not damage the slide rails.
Immediately investigate the reasons for any jamming and
take immediate action.
3 Shorten the conveyor chain to the right length. Fit the
pivot and the steel pin, using the special pin inser-
tion/removal tool.
After fitting, check that the steel pin is centered and
that the chain can easily bend in the fitted link.
4 Check that the slack is not excessive. See “Checking
the tension of conveyor chain” on page 9.
