Compression System - Suzuki Baleno Manual

COMPRESSION SYSTEM

General Information
When servicing the compressor, keep dirt or foreign
material away from getting on or into the compressor
parts and system. Clean tools and a clean work area
are important for proper service.
The compressor connection and the outside of the
compressor should be cleaned before any "On-ve-
hicle" repair or before removal of the compressor. The
parts must be kept clean at all times and any parts to
be reassembled should be cleaned with trichloroe-
thane, naphtha, kerosene or equivalent solvent and
dried with dry air. Use only lint free cloths to wipe
parts.
Diagnosis
Compressor troubles are mainly following three
types: gas leakage, noise and insufficient pressure.
Compressor gas leakages in most cases develop
from the shaft seal. When detecting gas leakage, al-
ways use a leak tester. If a small amount of oil seeps
out from the shaft seal, there is no necessity of replac-
ing the seal. The shaft seal has been designed to al-
low a small amount of oil to leak out for lubricating pur-

5 Oil and/or gas leakage
The operations described below are based on bench
overhaul with compressor removed from the vehicle,
except as noted. They have been prepared in order
of accessibility of the components.
When compressor is removed from the vehicle for
servicing, the oil remaining in the compressor should
be discarded and new refrigerant oil added to the
compressor.
Minor repair procedures may be done on the vehicle
without discharging the system. Major repair proce-
dures require that the system be discharged of refrig-
erant.
pose. Thus, the shaft seal should be replaced only
when a large amount of compressor oil is leaking out
or when gas leakage is discovered by using gas tes-
ter.
In regard to noise and insufficient pressure, repairs
should be made only after diagnosing the trouble
properly.
