5.2.1 BELT TENSION AND ALIGNMENT
5. Use a 10 pound weight to determine the
belt deflection in a static condition.
Fig. 5-14 Belt Deflection
6. Adjusting Tension:
a. Loosen the jam nuts on the adjusting
bolts. Loosen bearing bolts slightly.
b. Turn the adjusting bolt to set the tension.
Turn both bolts the same amount to
maintain pulley alignment.
c. Check the tension again.
Over tightening will cause belt stretching
and overload the bearing. Belts that are
too loose will slip, tear and wear rapidly.
Check alignment, see next section.
d. Tighten the jam nuts. Tighten the bearing
bolts.
e. Install and secure the belt cover with
two bolts.
