Wheel Clamps must be adjusted to compensate for
wheel runout. This adjustment is made using the three
Wheel Runout Adjusting Knobs.
1)
Raise wheel and tire from turning gauge or rear
wheel slip plate. Turn wheel so the large wheel
clamping knob is at the top (12 o’clock position).
2)
Mount the Spirit Level Gauge on the Wheel
Clamp. (See Figure 9) Center the magnet on the
Wheel Runout Compensating Adapter. Turn the
Spirit Level Gauge so it is level.
3)
Zero the Caster Spirit Level using the adjusting
knob on the bottom of the unit.
4)
Rotate the wheel so the wheel clamp adjusting
knob is at the 2 o’clock position. Turn the Spirit
Level Gauge so it is once again level. Note the
amount of movement of the bubble away from
zero.
Repeat at the 4, 6, 8, and 10 o’clock positions.
Re-level the Spirit Level Gauge at each position.
5)
Turn the wheel to the position where the largest
movement of the bubble was observed. Turn the
Runout Adjusting Knobs to decrease this reading
by one-half. Zero the Caster Spirit Level and
repeat step 4, checking for the largest movement
of the bubble away from zero at each of the six
positions.
6)
The wheel clamp is properly adjusted when the
bubble does not move away from zero at all six
positions.
