Drive Belt Maintenance
There are two drive belts that may become loose, worn or cracked. See Figure 1.
Primary Belt — This is the
wider of the two belts. It has
grooves that keep it aligned on
the large upper pulley. Unless
the unit has been serviced and
not put back together properly,
it is unlikely that the primary
belt will need to be
re-tensioned.
Secondary Belt — This is the
narrower of the two belts. It
has grooves that keep it
aligned on the flywheel’s drive
pulley. It is unlikely that the
secondary belt will become
loose because it is a stretch-fit
belt. Unless the unit has been
worked on and not put back
together properly, it is unlikely
the tension will change.
Follow this Drive Belt Maintenance procedure to ensure that the belts are
tensioned properly and in good condition. See the Service Schedule in this
chapter for a minimum schedule for checking the belt tension and condition.
NOTE: To remove and replace the belts a qualified service technician should
follow the Drive Belts procedure in the Service chapter.
