4.                       NOTE
Do not allow rear wheel to rotate when rotating sprocket.
A false measurement will occur.

     Rotate rear sprocket by hand in one direction until it stops.

5.   While holding sprocket in place, mark masking tape in line
     with the string.

6.   Rotate rear sprocket in opposite direction until it stops.

7.   While holding sprocket in place, make second mark in line
     with the string.

8.   Measure distance (2) between marks. If measurement
     exceeds distance allowed, replace rubber isolator.
