LASER BEAM AIMING ADJUSTMENT : Setting up the ICC Target Board
INFOID:0000000001756726
CAUTION:
Accuracy in setting up the ICC target board is essential for the laser beam aiming adjustment.
For details, refer to T echnical Service Bulletin.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale as shown.
2. Adjust the height of the target stand so that the point of the trian-
gle aims above the center of the ICC sensor.
ADJUSTING THE POSITION OF THE TARGET BOARD STRING
1. Attach a scale or straightedge (at least 350 mm [14 in] orlonger).
2. Suspend a string with a weight on the end 218 mm (8.6 in) to the left side of the target board center.
POSITIONING THE TARGET
1. Suspend a string with weights on each end over the cent erline of the vehicle. The string should lay over
the center of the front and bac k bumpers. Mark these centerpoi nts on the ground at each weight.

1. Apply red lead to the drive gear.
NOTE:
Apply red lead to both faces of three to four gears, at four loca-
tions evenly spaced on the drive gear.
2. Rotate the drive gear back and forth several times. Then check for correct drive pinion to drive gear tooth contact as shown.
CAUTION:
Check tooth contact on drive side and reverse side.
3. If the tooth contact is improperly adjusted, follow the procedure below to adjust the drive pinion height (dimension X).
• If the tooth contact is near the face (face contact), or near the heel (heel contact), use a thicker drive pinion height adjusting washer to
move drive pinion closer to the drive gear.
Refer to DLN-231, "
Inspection and Adjustment".
• If the tooth contact is near the flank (flank contact), or near the toe (toe contact), use a thinner drive pinion height adjusting washer to
move the drive pinion farther from the drive gear.
Refer to DLN-231, "
Inspection and Adjustment".
