Belts
Inspect belts frequently for wear and serviceability. Replace a
belt that shows signs of severe cuts, tears, separation, weather
checking and cracking, or burns caused by slipping. Slight
raveling of belt covering does not indicate failure, trim ravelings
with a sharp knife.
Inspect the belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against the
bottom of the groove. Replace the pulley when this is the case,
otherwise belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or damage
the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition in a
very short time.
Deck Belt Adjustment
The spindle belt tension remains constant by means of a
tension idler and spring. The spring tension should be such that
the belt does not slip under normal operating load conditions,
assuming the belt is not excessively worn or damaged. As the
belt stretches and wears in, adjustment may become necessary.
To increase belt tension, move the spring chain one (or more)
link(s) at the anchor point on the deck frame. Figure 7-11 &
Figure 7-12
IMPORTANT: Do not over tension the spring to compensate
for a badly worn belt or pulley.
