PULLEYS
In the event of the motor or compressor unit having
been removed and replaced, pulley alignment will
have to be checked and adjusted.
Misalignment of pulleys can cause rapid wear of the
V belt form, considerably shortening the service life
of both belts and pulleys. Due to Sullair's innovative
design, only parallel alignment of the drive pulleys
needs to be checked

ment.

greater than 0.5°.
