Parts Required: See Parts Pages.
Procedure:
1.
Set spinner control valve at “0” position to stop spinners.
2. Remove both belt shields, clean thoroughly and repaint.
3. Adjust processor to Manual operation. Select a slow Manual Speed so tracking is visual.
4. Move the front idler adjustment bolts to extreme rear position.
5. Shut down spreader. Pull out splice pin to separate belt splice.
6. Insert pin into one side of belt splice. Attach a winch to the belt splice and remove belt.
NOTE: If the splice pin cannot be removed, cut belt and remove belt by hand.
7. Using any suitable tool, remove any caked material from the drive pulley, snubber pulley, idler pulley and
from inside the frame channels. Clean and repaint as required.
8. Thread OLD splice pin through one end of new belt splice. Connect wire to pin about 1/4” in from each
side of the belt, forming a loop.
9. Thread the rope along the top of the belt channel, around the front idler pulley, over the snubber pulley,
and under the drive pulley.
10. Tie end of rope under drive pulley to wire loop. Wrap other end of rope once around drive pulley and out
to rear.
11. Start conveyor drive so drive pulley turns slowly. One person should pull on rope while other feeds belt
into unit from rear. Pull new belt under drive pulley, over snubber pulley, along frame channels, around
front idler pulley and back to drive pulley.
12. Shut off all power and insert lumber under belt to support its weight as shown in Figure 14.
Make sure power is shut off before performing this threading operation.
