Sprocket
Idler Pulley
1. Position the chain through the operator. Figure A.
2. Open the gate and line up the front bracket so the chain
is at the same level as the idler pulley and parallel to the
ground. Weld the front bracket. Figure C
3. Close the gate and line up the rear bracket so the chain is
at the same level as the idler pulley and parallel to the
ground. Weld the rear bracket in this position. Figure C
4. Connect the chain to the brackets using the chain bolt
and master links. Figure B, D, E
5. The chain should have no more than 1 inch (2.5 cm) of
sag (bend) for every 10 feet (3m) of chain length, Figure F.
Chain should not be too tight or too loose. If the chain is
too long, adjust the chain bolt position on the bracket or
remove links from the chain until you get your desired
length, Figure E.
