STEERING AXIS INCLINATION (SAI) READING
SAI: The inward tilt of the ball joint or strut at the top
.
Proceed with the following steps to read SAI:
1) With the Electronic Gauge mounted on the left
front wheel clamp, turn the left front wheel
outward at the front for a 20 degree reading on
the radius gauge. (Refer to Fig.19)
2) Turn the Electronic Gauge so it is level.
3) Set the selector to SAI. Press the Zero Button.
(See Fig. 23)
4) Turn the wheel inward at the front for a 20 degree
reading on the radius gauge. This is a total swing
of 40 degrees. (See Fig. 20)
5) DO NOT RE-LEVEL THE ELECTRONIC
GAUGE.
6) Read SAI on the Digital Readout Scale (A
positive 14.5 is indicated Fig. 23)
7) Repeat the above procedure on the right front
wheel.
