2. Rotate motor sprocket assembly until proper chain
tension is attained.
NOTE: Access to chain is thru cut out in lower side of
axle cradle.
3. Tighten mounting bolts.
NOTE: We do not recommend lubricating the drive
chains unless they become stiff because of rust. If the
chain rusts, it may be lubricated lightly with a
DRY-TYPE LUBRICANT. This will reduce the chance
for build-up of sand or other topdress material on
chain.
ADJUSTING CONVEYOR BELT
When conveyor belt is adjusted properly, the
compressed length of each compression spring
should be 4-7/16" (112 mm). Adjust conveyor belt
as follows:
1. Loosen jam nuts and adjust tension rod nuts to
attain desired tension.

3. Check to insure that the center distance between
conveyor belt roller shafts (Fig. 20), on each side of
machine, are equal distance (approximately 35-1/4").

REPLACING CONVEYOR BELT
When replacing a damaged or worn conveyor belt,
always inspect hopper seals (Fig. 21) and gate edge
(Fig. 21) for wear or torn edges. Replace worn or torn
components to insure proper operation of new
conveyor belt.
