1. Remove chain cover plate from the boot or hopper.
2. Check chain slack.
• Chain slack is checked at the midpoint of the longest span. It should be no
more than 1/4” (6 mm).
Note: The Hopper has 2 chains, 1 for each flighting.
3. Adjust the chain slack.

bearing and adjust the chain slack (Figure

If the chain can’t be tightened enough, remove a
link from the chain. If the chain will not fit with one
link removed, add a half link to the chain and
replace.

flighting bearing on the side that needs
adjustment and set the chain slack (Figure
