Refer to the Control Arm Detail and Cap Latch Detail on for component part assembly. The cap
latch hook, located opposite the cap hinge, latches over the BLK-11846 Hold Down Bracket
(Item 20, Cap Latch Detail on
Page 19 ). One end of the ground control chain is secured at the
counterweight arm with a cotter pin (See Figure 7P) . The chain is passed up and over the cap,
through the grommet on the pivot arm, and through the Roof Eave Bracket (BLK-11950), then
continues down the side of the tank.
After removing the slack from the ground control chain while in the fully closed and latched
position. Install the key ring clip 2'' below chain holder bracket
(See Figure 7R) . Ensure that the
key ring allows the cap to fully latch when the cap is in the closed position, yet will not allow the
chain enough slack on top of the cap to become wrapped around the pivot arm in a high wind
condition.

Make sure the loop of the Main Cap Spring (BLK-11623) is held securely in the preloaded
position by the head of the 5/16" Bolt beneath (Item 4, Control Arm Detail
See Figure 7T ). If
necessary, place one or more 5/16" flat washers under the bolt head to ensure that the bolt
catches the loop. See Stop Bolt Detail on
Page 34 .
