Belt Tension
Frequently inspect the V-belt tension during
the first twenty hours of break-in operation.
During this period, the belts will stretch and
seat, which can generate a fair amount of
black dust inside of the belt cover. This dust
buildup is a normal condition during planer life
since the cover retains the dust.
However, it is very important that you check
the drive belts so
all belts have the same
tension
(belt deflection) after the break-in
period. If one belt is looser than the others you
must align the pulleys.
When replacing belts, always replace belts as a
matched set.
To adjust belt tension, lower the motor slightly
by loosening the lower jam nut shown in
Figure
40 . When belt tension is satisfactory, tighten
the upper jam nuts down onto the motor
bracket to secure it.
DO NOT over-tighten the jam nuts if the motor
mount casting ear is tilted and the nuts do not
contact the casting ear surface evenly (See
Figure 40
). The ear can snap off. Merely snug
the jam nuts.
Pulley Alignment
The V-belt pulleys must be aligned with each
other so all belts share the same belt tension
(deflection). If the belts do not share the same
work load, belt life will suffer. Check the
alignment with a good quality straightedge as
shown in
Figure 41 .
To align the pulleys:
1. Loosen the belt tension jam nuts so the
motor will freely move up and down.
2.
Loosen, but do not remove, the bolts that
secure the motor to the motor mounting
plate.
3.
Slide the motor as needed to align the pulleys.
4.
When the pulleys are aligned, tighten the
motor mount bolts.
5. Tension the V-belts and replace the belt
cover.
