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. It is
unlikely that the primary belt will become loose because it is a
stretch-fit belt.
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.
NOTE: If a belt has cracks or appears worn, it must be
replaced immediately by a qualified service technician.
