LASER TOOL • English<br />
18<br />
Measuring for Misalignment:<br />
1. Direct beam toward target pulley.<br />
2. If <strong>laser</strong> beam strikes top (center) of second rib (measured from outside of pulley.<br />
farthest fromm engine) pulleys are aligned.<br />
3. If <strong>laser</strong> beam does not strike top (center) of second rib, see table below for accep<br />
table tolerances.<br />
4. If alignment is within tolerance, reverse direction of beam by moving <strong>laser</strong> to target<br />
pulley and check alignment back to original pulley. If beam is now out of tolerance,<br />
pulleys have angular misalignment.<br />
5. If beam is still within tolerance, proceed to testing other pulleys.<br />
6. If beam is out of tolerance when tested in both directions, pulleys have horizontal<br />
misalignment.<br />
Note - Because crankshaff puffer is difficult to adjust, it should be used as reterence<br />
point tor aligning other pulleys.<br />
Testing for Pulley Run-Out or Bent<br />
Accessory Shaft:<br />
1. The <strong>laser</strong> <strong>tool</strong> on base pulley and aim beam at target pulley.<br />
Rotate target pulley and observe movement of beam.<br />
2. If beam moves outside acceptable tolerance range when rotating target pulley,<br />
pulley runout is unacceptable, component shaft is bent or accessory bearings are<br />
faulty.<br />
Acceptable Alignment Tolerances:<br />
Pulleys are within acceptable alignment if beam is within following ranges:<br />
Distance Bettween Variance of Beam from<br />
Laser & Pulley Top Center of Second Rib<br />
6" or 152 mm 1/2 rib<br />
12" or 305 mm 1 rib<br />
18" or 457 mm 1-1/2 ribs<br />
24" or 610 mm 2 ribs
