5. Remove retaining rings on the link pins of the link

to be removed.

WARNING: Use caution when pulling chain for
section removal. The chain should be held back so
that a runaway condition does not occur. This can
happen when the weight of the chain outside the
conveyor overcomes the friction of the chain still
inside the conveyor, causing all the links to feed
out uncontrollably.

6. Remove bearings and thrust washers from one

side only. Retain thrust washers for reassembly.

7. Pull pins with remaining bearings through all four

ears of the link connection.

8. Once the link has been removed, place the link on

a work bench and remove the bearing locknut.

9. Using a soft aluminum bar, drive out the

worn bearing.

10. Press in a new bearing and install a new locknut.

11. Place the link back into position so that

alignment of the link ears will permit insertion of
the link pin.

12. Insert pins through all four ears of the link

connection.

13. Reinstall bearings and thrust washers.

14. Tighten the tensioning screws.

15. Reinstall retaining rings on the link pins.

16. If other links are to be removed, it will be

necessary to hand crank the drive (due to the
lack of chain tension) until the link to be removed
is exposed at the take-up end. Repeat Steps 5
through 15 as many times as required to replace
all worn followers.

NOTE: When rebuilding all links, the chain can be
removed in large sections by breaking the chain at
the drive end as well as at the take-up end. Pull a
manageable length of chain out from take-up end. It
is recommended that links be reassembled in the
same order as received from DE-STA-CO. Number
links before disassembly.

17. When all followers are changed, re-tension the
chain as described in the “Conveyor Tension Setting”
section of this manual.
