13. Move each brush hanger from the center of the wash tunnel so that it is parallel to vehicle
travel. With each brush hanger in this position check that the hanger is level. Up or down
adjustment of the brush hanger can be achieved by placing shim material under the
brush hanger pillow block bearings.
14. Double check that the bottom pillow block bearing for each brush hanger is EXACTLY
below the top pillow block bearing. This is necessary to provide light brush pressure
against the side of the vehicle.
15. Mount the Brush Head, Shaft and Core assembly to each Hanger Arm.
16. Run and install the power to each brush.
17. Rotation of the Brushes is with vehicle travel. As viewed from the top of each
Brush the DRIVER side turns COUNTERCLOCKWISE and the PASSENGER side
turns CLOCKWISE. Rotation of the top brush is against vehicle travel. As viewed
from the driver side the brush turns COUNTERCLOCKWISE. If brushes are
rotating in the wrong direction, rewire for correct rotation.
Rotation speed of each Brush should be according to the
Operating Speeds
Chart
in the
Adjustments and Testing
section of this manual.
18. Install the air retract cylinder and run the air lines to the manifold for the retract operation.
