Linkage Rod Adjustment

Adjustments can be made to linkage rods by removing clevis cotter hairpin (268), clevis (179) pin, loosening nuts (128), and then turning clevis as required to lengthen or shorten rod connectors.

To ensure proper application of beads and thermoplas- tic, make sure screed box linkage rod (182) measures 16.875 in. (42.8 cm). Be sure to measure where nut

(128)meets clevis (179) when checking for proper link- age rod length.

16.875 in.

Adjust the bead box linkage rod (181) so bead box drive is touching ThermoLazer tire when screed box is in down (but not open) position. A slight downward force on the bead box linkage should be required when insert- ing the clevis pin through the clevis deployment bar.

1.With screed box in down (but not open) position, rotate the bead box wheel by hand.

2.If the wheel does not cause the ThermoLazer tire to rotate both forward and backwards, loosen nuts (128), clevis cotter hair pin, clevis pin, and rotate the clevis (179) one turn counterclockwise.

3.Reconnect clevis to deployment bar and again rotate bead box wheel to see if adjustments cause ThermoLazer to move forward and backwards.

4.Continue to rotate clevis 1/2 turn counterclockwise until rotating bead box wheel causes ThermoLazer to move forward and backwards.
