Compressor Pulley: Service and Repair
Belt Pulley, Zexel/Valeo
Belt Pulley, Zexel/Valeo
‹› Observe notes for removing belt pulley for compressor manufactured by "Denso" version "1", these also apply to this A/C compressor. Refer to =>
[ Belt Pulley, Denso Version 1 ] See: Description and Operation
‹› Perform any preliminary work as described for removing belt pulley on compressor manufactured by "Denso" version "1".
‹› Beginning the production year 2006, the name of the "Zexel" A/C compressor was changed from "Zexel" to "Valeo".
Removing drive plate
‹› On A/C compressors with part number 1K0 820 803 as of index " N", the drive plate splines are bonded to A/C compressor shaft splines.
‹› On A/C compressors with part number 1K0 820 803 up to index " L", the drive plate splines are not bonded to A/C compressor shaft splines,
removing drive plate. On these A/C compressors it may be possible that the drive plate splines are worn off and the A/C compressor is no longer
driven. In this case, check the A/C compressor for freedom of movement and if necessary replace drive plate, use the repair set 1K0 898 814 to do
so.
-
Hold belt pulley - A - firmly in place using a conventional band wrench (with webbed band) and loosen bolt - B -.
‹› If drive plate overload protection - D - has triggered, the belt pulley turns freely without driving the A/C compressor. Check the A/C compressor
for freedom of movement by turning at bolt - B -, replace a A/C compressor with belt pulley that turns with resistance. If compressor moves freely,
in this case remove bolts - C - and remove drive plate. Then hold drive plate hub firmly in place using pliers to loosen bolt - B -.
‹› If belt pulley splines have been worn away, bolt - B - cannot be loosened (compressor turns along with the bolt). In this case, remove the bolts - C
- and tension drive plate with washer - A - (flat side faces outward), washers - B - and bolts - C - (contained in repair set 1K0 898 814) on to A/C
compressor shaft.
