SUBJECT:
1984 A/C COMPRESSOR SHAFT SEAL USAGE
MODELS AFFECTED:
ALL EQUIPPED WITH AIR CONDITIONING
A new A/C compressor shaft seal has been implemented on all R-4 and DA-6 A/C compressors during the 1984 model year. A new one-piece lip seal has
replaced the two-piece ceramic carbon seal. The lip seal is a quality improvement and is anticipated to improve shaft seal field performance. Inspection
and shaft seal service must be made as follows:
^
DA-6 compressor originally produced with two-piece ceramic carbon seal must be serviced with a two-piece seal (Part Number 2724280).
^
DA-6 compressors produced with the one-piece lip seal must be serviced with a one-piece seal (Part Number 2724319).
^
R-4 compressors originally produced with the two-piece ceramic carbon seal must be serviced with a two-piece seal (Part Number 12301828) for
proper shaft seal function.
^
R-4 compressors originally produced with the one-piece lip seal may be serviced with either a one-piece seal (Part Number 2724319) or the
two-piece seal (Part Number 12301828).
