OPERATIONAL PERFORMANCE TEST / Wheel Loader Test CONTROL LEVER STROKE Summary: 1. Plays and operating conditions of operating levers, pedals and steering wheel are confirmed, and their strokes are measured. 2. Measurement of each levers is performed at the tip of the grip. Measurement of each pedals is performed at the top of the pedal. 3. In case lever stroke play is present in the neutral position, add half (1/2) the play present to both side lever strokes. Preparation: 1. Keep hydraulic oil temperature at 50 ± 5 ° C (122 ± 9 ° F). Measurement: 1. Measurement of Operating Lever 1-1. Place the bucket bottom onto the ground. 1-2. Stop the engine. 1-3.
Measure the stroke from the neutral position to the stroke end of each lift arm, bucket and FNR lever at the top center of the grip. 2. Measurement of Pedal 2-1. Place the bucket onto the ground. 2-2. Stop the engine. 2-3. Measure the stroke from the neutral position to the stroke end of the pedal at the top of the pedal. 3. Measurement of Steering Wheel 3-1. Start the engine. (Low idling) 3-2. Float the bucket slightly above the ground. 3-3. Measure the number of rotations while rotating the steering wheel from the left stroke end to the right. Measure the distance in direct distance. 4. Repeat measurement three times and calculate the average values. Evaluation:
