COMPRESSOR INPUT SHAFT, LOOSENING AND TIGHTENING
Loosening
Note. Extensive preparations are needed to loosen the compressor driveshaft. Refer to A/C COMPRESSOR WITH DRIVE UNIT . The driveshaft can be checked and tightened without opening the refrigerant circuit. Refer to DRIVE PLATE WITH OVERLOAD PROTECTION, CHECKING RUN-OUT AND ADJUSTING .
Remove the components that prevent access to the driveshaft. Refer to A/C COMPRESSOR WITH DRIVE UNIT .
Hold the A/C compressor driveshaft -A- in place using a wrench and turn compressor drive unit -B- in the direction of the arrow -C-.
Note. Do not turn the driveshaft -A-. Driveshaft -A- can be slid into drive wheel through the boot -E- after loosening threaded connection. After installing the driveshaft -A-, check the boot -E- installation position.
Tightening
Hold the compressor driveshaft -A- in place using a wrench and turn the compressor drive unit -B- in the direction of the arrow -D- tightening specification 60 Nm.
After tightening the compressor driveshaft, check the boot installation position -E-.
