Subject:
SHAFT NUT REMOVAL FROM THE HR6HE AIR CONDITIONING COMPRESSOR

Model and Year:
1993 ALL PASSENGER CARS AND TRUCKS WITH HR6HE COMPRESSOR

Effective April 29, 1991 the shaft nut on the HR6HE compressor has been removed on all production and service compressors.

Elimination of the shaft nut has been made possible through improved plant quality controls which assures proper press fit of the clutch driver to compressor shaft.

When it is necessary to turn the compressor shaft to perform service leak testing, a M9 x 1.25 threaded nut must be installed on the shaft to facilitate turning of shaft with a wrench.
