Measurement Method and Main Unit Posture

Measurement Method and Main Unit PostureNew Machine Performance Section

SH330

Engine SpeedMeasurement method

[1] No load operation mode at high idle:SP mode, H mode and A mode speed

[2] Operation mode at low idle: SP mode speed

Main unit posture: bucket on ground

Pressure in Each SectionMeasurement method

[1] Engine high idle

[2] Oil temperature is 45- 55

[3] Travelling and swing is measured between the counter bal-ance and motor.

[4] Measure the main relief pressure before adjusting the over-load pressure, and then measure the overload pressure afterthe main pressure has been increased to a level as high orhigher than the overload pressure. Return the main pressureto regulation pressure after measurement.

Main unit posture: operate each attachment in the travel pos-ture.

Cylinder Falling AmountMeasurement method

[1] Have oil flow into each cylinder before measurement with the oil at 45- 55(Record the oil temperature before and after measurement)

[2] Make the height of the boom foot pin and the bucket pin the same.The arm cylinder is fully retracted, and the bucket cylinder is fully opened.

[3] Engine is stopped.

[4] After 10 min., measure the extension amount and retraction amount of the boom, arm, and

bucket cylinder rod.[5] Along with measuring the movement amount of the cylinders after 10 min., measure the tip dis-

placement.

Attachment SpeedMeasurement method


[2] Oil temperature is 45- 55 .

[3] No load

Main unit posture

Boom cylinder

With the arm fully out and the bucket fully opened,measure the operation time it takes the boomcyclinder to go from fully upwards to the groundand also from the ground to fully upwards[Note] When the boom is lowered, make sure not

to directly hit the concrete (place tires onthe ground).

Arm cylinder

With the arm cylinder fully out and the arm hori-zontal to the ground, measure the operation time ittakes the arm cylinder to do a full stroke withbucket cylinder fully out

Bucket cylinder

Measure the operation time for a full stroke at themaximum radius.

Swing SpeedMeasurement method



[3] No load

[4] The time required for the next rotation after one rotation

Main unit posture

Swing (180) Brake AngleMeasurement method



[3] No load

[4] Swing 180and measure the flow angle after neutral braking

Main unit posture: same as the above

Travel SpeedMeasurement method

[1] Engine high idle and oil temperature is 45- 55with no load.

[2] Measure the required time to travel 6 m after a 4 - 5 m running start. If the off travel distance is1 m or more, however, use the off travel distance as a reference value to correct the off travel,then measure the travel speed again.

[3] Travelling should be done on concrete.

[4] Conduct both high-speed and low-speed travelling.

Off Travel AmountMeasurement method

[1] Engine high idle and oil temperature is 45- 55with no load.

[2] Measure the required time to travel 20 m after a 4 - 5 m running start.

[3] Shoe tension amount should be standard.

[4] Measure for both forward and backward traveling.

[5] Measure for both high-speed and low-speed traveling.

Main unit posture: same as with travel speed measurement.

Travel Sprocket SpeedMeasurement method


[2] Oil temperature is 45- 55.

[3] Raise a shoe, and after achieving a constant speed, measure thetime required for the sprocket to rotate 10 times both forwardsand backwards.

[4] Measure for both high-speed and low-speed traveling.Main unit posture: 90swing, shoe raised.

Shoe Tension AmountMeasurement method

[1] Raise the shoe and, at the central position of the track, measure the gap between the undersideof lower side frame and the topside of the shoe plate.

[2] Measure for both the left and right sides.

Swing Ball Race Bearing Movement Amount and Bucket Tip Movement AmountMeasurement method

A) Up and down direction measurement

[1] Measure the up and down movement amount at two locations in front of and behind the ballrace.

[2] Move the arm cylinder out and close the bucket cylinder, and move the bottom surface of thebucket 30 cm above the ground. Attach a dial gauge to the lowering section as shown in thefigure below and do zero point adjustment.

[3] Jack up the main unit and measure the amount of movement with the dial gauge.* Jack up the main body until the swinging of the dial gauge becomes constant.

Main unit posture

B) Left and right direction measurement[1] Measure the left to right movement amount at the front side of the ball race and the left to right

movement amount of the bucket tip.

[2] The arm cylinder and bucket cylinder are in the open position, apply 294.2 - 392.3 N of forceto one side, and zero point adjustment is done for these conditions.

[3] 294.2 - 392.3 N of force is applied to the opposite side and the left to right movement is mea-sured.
