CHOPPER DRIVE BELT TENSION AND ALIGNMENT
A belt transmits rotational power to the
chopper. It must be kept properly ten-
sioned and the pulleys aligned to obtain
the expected performance and life.
To check the tension and alignment, fol-
low this procedure:
1. Clear the area of bystanders, espe-
cially small children.
2. Place all controls in neutral, stop en-
gine, set park brake, remove ignition
key and wait for all moving parts to
stop before dismounting.
3. Remove guard over belt.
4. The chopper drive belt tension is set
by an idler pulley:
a. The belt should be set so that it
does not slip when operating.
b. The belt tension is correct when
the center of the long span de-
flects 1/4 inch (6 mm) from a 10
lb force.
c. Move the spring anchor bolt to
a new position to provide the
required coil spacing if the coil
spacing is less than 3 mm (1/8
inch) when engaged.
WARNING
Machine is shown with guard
removed for illustrative purposes
only. Do not operate machine
with guard removed.
5. Release tensioner and disconnect
chain coupler when replacing belt.
