ADJUSTING MOTOR MOUNTING
TRACKING
MAKE CERTAIN THE MACHINE IS DISCONNECTED
FROM THE POWER SOURCE.
WARNING
!
Motor mount tracking is a coarse adjustment. Use the
adjusting belt tracking section first.
If proper tracking can not be achieved then use this
procedure. To adjust the motor mount tracking:
1. Loosen the four motor mounting bolts, two of which
are shown at (L).
SEE FIG. 15.
2. Loosen the two motor tracking lock nuts (M).
3. Turn one motor tracking bolt (N) in a 1/4 turn and
rotate the belt by hand. Observe the direction the
adjustment is causing the belt to track. If the belt
has moved in the correct direction go to step 5.
4. If the belt tracked the wrong direction, back the
motor tracking bolt (N) to its starting position. Turn
the other motor tracking bolt (N) in 1/4 turn and
rotate the belt by hand. This should change the belt
tracking to the proper direction.
5. Tighten both motor tracking lock nuts (M) making
sure the motor tracking bolts (N) do not move. Then
tighten the motor mounting nuts (L). Return to the
Adjusting Belt Tracking section to finish the fine
adjustments to the belt tracking.
