When the Push-Pull Gauge Is Used
WHEN THE PUSH-PULL GAUGE IS USED1. Before the looseness check, check the items below.
1) Check that the Mitsubishi genuine wheel with specified size is mounted. Also check that the wheel bearing is not loose. (Front Axle)
2) Raise the vehicle at the jack up point on the side sill of the inspection side, and lift the tire for approximately 30 mm. At this time, check that the tire of the opposite side is grounded.
2. Install a dial-gauge respectively to the "Position a (front side position)" and "Position b (rear side position)" on the wheel rim, 25 mm below from the wheel center. (Install the dial gauges to the smooth position that is around the edge of the tire.)
3. The push-pull gauge shall be set to the smooth position that is 25 mm above from the wheel center and the edge of the tire on the wheel rim. Then the position on the vehicle front side shall be the "Position A" and the vehicle rear side shall be the "Position B".
4. To stabilize the relationship between the load and fluctuation, push with the specified load by 10ON of "Position A, "Position B", and "Position A" using the push-pull gauge. Note that the pushed load on each position shall be extracted.
5. Using the push-pull gauge, carry out the procedure below to read the value on the dial gauge and calculate the looseness.
NOTE: The ± sign acquired with the calculation result shall be used as it is.
1) While pushing the "Position B" with the specified load by 100N, read the values on the dial gauges at the "Position a" and "Position b". The values of the dial gauges at this time shall respectively be "aB" and "bB".
2) Remove the load in the "Position B". Then while pushing the "Position A" with the specified load by 100N, read the values on the dial gauge in the "Position a" and "Position V. The values on the dial gauges at this time shall respectively be "aA" and "bA".
3) Make calculation taking the value differences of the dial gauge positions a and b which were read while pushing the "Position A" and "Position B" as each fluctuation.
^ Fluctuation of the dial gauge position a: aA - aB
^ Fluctuation of the dial gauge position b: bA - bB
4) Calculate each fluctuation difference of the dial gauge positions a and b acquired above for looseness. Perform the procedure above twice. Fluctuation of the dial gauge position a - Fluctuation of the dial gauge position b
5) Calculate the average of the looseness calculated twice.
6. If the average exceeds the standard value, check the ball joint rotation torque. (Tie Rod End Ball Joint Rotation Torque Check)
Standard value: Within ± 2.0 mm
NOTE: Measure the tie-rod looseness on the right side and left side respectively.
