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.
a. For the Boot: loosen the 4 bolts of the lower
bearing and adjust the chain slack (Figure
5.3).
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.
b. For the Hopper: loosen the 2 bolts of the
flighting bearing on the side that needs
adjustment and set the chain slack (Figure
5.4).
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.
4. Lightly oil the chain.
