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 of the operating levers is made at the tip of the grip. Measurement of each of the pedals is made at the top of the pedal. 3. In the case of existence of play at neutral, make measurement by dividing it on both sides evenly. Preparation: 1. Keep the hydraulic oil temperature at 50 ± 5 ° C (122 ± 40 ° F). Measurement: 1. Measurement of Operating Lever 1-1. Have the bucket bottom contact the ground. 1-2. Stop the engine. 1-3.
Measure the stroke from the neutral position to the stroke end of each of the lift arm, bucket, and forward-reverse operating levers at the top center of the grip. 2. Measurement of Pedal 2-1. Have the bucket contact 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. Have the bucket float slightly above the ground. 3-3. Measure the number of times of rotation re- quired for reaching the left stroke end from the right, and vice versa of the steering wheel. 4. make measurement corresponding to a straight line. 5.
Make measurement three times, and determine the measurement value by obtaining their mean values. Evaluation: Refer to the Performance Standard Table in Group T4-2. T4-4-13
