5.6.2 Denso A/C Compressor (Version 2)
Note
♦
Pay close attention to instructions for removing and installing
the belt pulley -E-. Refer to
⇒ “2.4 Belt Pulley, Denso A/C Compressor, Version 1“,
page 52 .
♦
Perform preliminary work as for removing belt pulley, refer to
⇒ “1.1 A/C Compressor Belt Pulley, Replacement“, page 24 .
♦
Belt pulley is made of plastic and is sensitive to impact, there‐
fore handle it with especial care.
♦
If the drive plate -C- overload protection activates, rotate the
pulley -E- using the outer part of the drive plate -C- so that the
compressor shaft -B- and the hexagon head on the drive plate
-D- (inner part of the drive plate -C-) do not rotate.
Removal
– Remove the cap -A-.
– Hold the A/C compressor input shaft -B- for example, with a
standard Allen wrench (7 mm) and turn the drive plate -C- to‐
gether with the pulley -E- in the direction of the -arrow-.
Note
The torque to drive the A/C compressor is transferred to the drive
plate -C- via the threaded connection. If, while the A/C compres‐
sor is working, the drive plate -C- was attached to the A/C com‐
pressor shaft so tight, that it cannot be loosened (the 7 mm Allen
wrench -B- cannot transmit the necessary torque) then the A/C
compressor must be replaced.
– Remove drive plate -C-.
