CROSS CONVEYOR
ADJUSTMENT
Proper tension should be maintained on cross con-
veyor chain when operating box. To adjust cross
conveyor, loosen the jam nuts (A) on tightener
bolts (B). Move adjusting nuts (C) on tightener
bolts until proper tension on chain is reached. The
chain is properly adjusted when the center slats
clear the bottom return pan by about 1/16 of an
inch. Adjust both sides equally. Lock in place with
jam nuts.
SHEAR BOLT
The cross conveyor is protected by two shear
bolts, located in the drive sprocket and shear hub
assembly, located at the right hand end of cross
conveyor. Two spare shear bolts are provided.
Always determine the cause of failure and elimi-
nate the cause before installing new shear bolts.
Use only H&S shear bolts, part number RGB38
when replacing shear bolts.
