Adjusting Feeder Conveyor Chain

IMPORTANT: Check chain tension (both sides), every 100 hours. Adjust chain when outside strand touches front of the runner channel (D).

To adjust chain:

Open feeder house shields.

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

Adjust eyebolt (B) with adjustment nuts (C) on both sides of feeder house, until left-hand and right-hand side outer chains contacts runner past air flow opening. The runner at the center of the inspection door at (E).

Tighten jam nut and eyebolt adjustment nuts.

The chain should be no tighter than runner contact at center of the door opening at (E).

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; and premature chain wear are often caused by excessive chain tension.

Excessive chain tension can result in air flow fan inlets bridging with crop material. A properly adjusted chain allows the tips of the conveyors slats to wipe the inlets clean.

When the adjusting eyebolt can go no further and the chain needs more tensioning, remove a offset link See Removing Conveyor Chain Links in this manual).

Close shields.
