Feeder House Conveyor Chain-Adjusting

Open feeder house side shields on both sides.

Set conveyor drum height adjust handles to small grain position.

Loosen drum adjust nut (A) on both sides of feeder house.

IMPORTANT: Do not over-tighten chain to make center strands as tight as outer strands. Center strands normally sag more because of weight of slats and upward force from crop material.

Adjust eyebolt (B) with adjustment nuts (C) on both sides of feeder house until left-hand and right-hand side outer chains contact runner at center (F) of inspection door (D).

Tighten drum adjust nut (A) on both sides to specification.

  • Check tension on both sides every 100 hours. Adjust when outside strands touch front of runner channel (E). Adjust no tighter than runner contact (F) at center for inspection door.
  • Do not over-tighten chain to make center strands as tight as outer strands. Center strands normally sag more because of weight of slats and upward force from crop material.
  • Bent eyebolts indicate excessive chain tension or slug feeding.
  • Out-of-round sprockets or drum and bent shafts can cause chain tension to be uneven, too tight, or too loose.
  • Shaft and bearing failure are often caused by excessive chain tension.
  • When adjusting eyebolt can go no further and chain needs more tensioning, remove a half link.
