Free roller type
- Align the free rollers with the wheel base and tread, then set them on the floor properly.
- Drive the vehicle slowly onto the tester roller and free rollers.
- Start the engine and accelerate gradually to inspect the speedometer.
- After inspection, decelerate gradually with gentle braking.
Scheme 42
- Remove the propeller shaft. (See PROPELLER SHAFT REMOVAL/INSTALLATION article.)
- Place the front wheels on the tester roller.
- Accelerate gradually and inspect the speedometer.
- After inspection, decelerate gradually with gentle braking.
- Install the propeller shaft. (See PROPELLER SHAFT REMOVAL/INSTALLATION article.)
Scheme 43
- Place the wheels (front or rear) to be measured on the tester roller.
- Shift to the N position/neutral.
- Activate the tester roller and measure braking force. If there is a large amount of brake drag force, the electronic control system coupling may be affected. Jack up all four wheels to eliminate the effect of the coupling and rotate each wheel by hand to verify the rotation condition.
Scheme 44
- Jack up all four wheels.
- Support the wheels (front or rear) on the side to be measured (near the wheels) using a wheel balancer sensor stand.
- Support the wheels on the side not to be measured (near the wheels) using safety stands.
- Set up the wheel balancer and rotate the wheels using engine drive to measure the wheel balance.
