SHEAR PIN HUBS
1. The spreader drive train is protected with a shear
pin hub at the front end of the side drive shaft. If the
shear bolts shear, determine cause of overload and
correct.
2. Realign holes in sprocket and shear pin hub and re-
place bolts. Snug lock nuts only enough to remove all
slack. Do Not Tighten completely.
Use 3/8x1-1/4" Grade 2 bolts and 3/8" lock nuts
only. Figure 12.
ADJUSTMENT
Apron Chain
The apron chain is adjusted by (2) adjuster
screws located on the front of the box frame. Adjust the
screws so there is no chain sag on the return side and
chain is never closer than 5" to the spreader axle.
When there is no more adjustment left on the adjuster
screws, loosen the nuts on the screws and push the
screws in as far as they will go. Then remove a link
from each chain and readjust the apron chain. Figure
10.
Roller Chain Adjustment
The front, main beater drive chain is automatically
tensioned with a spring loaded tensioner. Proper chain
tension is 1/2 to 3/4" of deflection at midspan on the
loaded chain strand. The automatic tension can be ad-
justed with the spring eye bolt. Figure 12.
The upper beater drive chain is automatically ten-
sioned with a spring loaded tensioner. Proper chain
tension is 1/2 to 3/4" of deflection at midspan on the
loaded chain strand. The automatic tension can be ad-
justed with the spring eye bolt. Figure 9.
