7.2 Wheel Scanners
Not all sites use wheel scanners. If your site doesn't use them, skip the instructions below and
go to the next chapter.
To align the
Type II/Type III
wheel scanners:
1
Be sure that you have on hand a T-handle 1/4-inch hex-wrench, a combination
9/16-inch open-end box wrench, and an STC alignment fixture.
2
Turn off all power to the scanners.
3
Using a T-handle 1/4-inch hex-wrench, loosen the socket-head-cap screws on the
cover of a wheel scanner.
The
Type II
wheel scanner has two socket-head-cap screws that attach the weather
cover to the mount.
The
Type III
wheel scanner has six. Four that attach the weather cover to the
mounting plate and two that attach the mounting plate to the mount.
4
Separate the wheel scanner cover-and-module assembly from its mount.
