4. Operation

4.1. Measuring Camber Angle

NOTE! Before use remove magnet protective plate. Replace after use.

1. Drive vehicle forwards to centralise wheels.
2. Fit gauge in centre of vehicle wheel/hub.
3. Set D bubble to centre and read the position of A bubble.
4. NOTE! Refer to the owner's handbook before making any adjustments.
5. NOTE! Any adjustments you make to either castor or camber angles may affect the other, so re-check all measurements after any adjustments have been made.
6. NOTE! Try to simulate normal running conditions, ie. half a tank of fuel and a weight similar to the driver in the front seat.

4.2. Measuring the Castor Angle

1. Drive vehicle forward so front wheels are positioned on steering turntables in the straight ahead position, rear wheels on level plates.
2. Fit gauge in centre of wheel/hub and set D bubble to centre.
3. Set B bubble to 0° with adjusting screw and turn the front wheel to 20° in.
4. Set D bubble to centre again and read the scale of B bubble.
5. NOTE! Refer to the owner's handbook before making any adjustments.
6. NOTE! Any adjustments you make to either castor or camber angles may affect the other, so re-check all measurements after any adjustments have been made.
7. We recommend the use of turntables Model No. GA44 when checking the caster as this will enable you to accurately set the wheels at 20°.

4.3. Measuring the Kingpin Inclination

1. Drive vehicle forward so front wheels are positioned on steering turntables in the straight ahead position, rear wheels on level plates.
2. Turn the front wheel to 20° out.
3. Fit gauge in centre of wheel/hub and set D bubble to centre.
4. Set C bubble to 0° with adjusting screw and turn the front wheel to 20° in.
5. Read scale of C bubble.
6. NOTE! Refer to the owner's handbook before making any adjustments.
