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

ensure that the belts are tensioned properly and in
good condition. See the
Service Schedule

belt tension and condition.

If a belt has
cracks or appears worn, it must be replaced
immediately by a qualified service technician.
