3. Slide two pieces of 1/4" inch thick bar stock between the upper and lower portions
primary pulley and the frame as shown Diagram 5.4.
4. Use the two adjustment bolts, shown in Diagram 5.4, to align the primary pulley square
to frame and a 1/4" from the frame.
5. Torque the four pillow block mounting bolts to 60 - 65 foot pounds (720 - 780 inch
pounds).
6. Test the alignment of the drive belt by pedaling the unit in both the forward and reverse
directions. The drive belt must remain squarely on the pulley face, not riding off the
edge of the pulley, with no belt noise being generated.
7. Replace the covers removed in step 1.
