c.
Adjust the tensioning devices to center position

Pull the conveyor belt tight through the freezer and determine which drive links cut to
shorten the belt. See Figure 1 in Appendix A.
e.
After cutting out the links, pull the belt ends together and join together with the splice rod;
being sure to thread all mesh properly. The threaded end should be on the side that would
cause the nut to rotate clockwise should the bottom of the nut ride up the top of the belt
supports which would prevent the nut from unscrewing itself.
f.
Run the nut on the splice rod and peen it on securely.
g.
Adjust the tensioning devices. Remember the conveyor belt will shrink and become shorter
when cooled to an operating temperature in the minus degrees, so check operation of belt
under cold operating conditions.
