NOTE: Due to the availability of different front end
accessory drive configurations, this procedure is meant to
be generic. Some front end accessory drive configurations
may require the refrigerant compressors to be aligned
with the other pulleys. Make sure all drive pulleys and
idler pulleys are in alignment with one another. The
components with shorter belt spans are the most critical
and require special attention. Cummins Inc. recommends
the use of the laser alignment tool, Part Number 3163524.
