A3 Quattro V6-3.2L (BUB) (2008)
‹› Tightening specification 17 Nm
2
Screw
‹› To loosen and tighten bolt, hold belt pulley firmly in place using a standard band wrench (with webbing).
‹› Clean threads on A/C compressor shaft (and on bolt if necessary) of old thread locking compound before screwing on.
‹› Install the bolts with thread locking compound (for example, D 000 600 A2).
‹› Tightening specification 7 Nm
3
Drive plate
‹› the overload protection takes over when the torque is excessive (for example, if the A/C compressor runs with resistance) and the belt pulley
runs freely without driving the A/C compressor.
‹› With rubber element for decoupling belt pulley from A/C compressor driveshaft (damps vibrations and noise).
‹› 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,
removing drive plate. Refer to => [ Belt Pulley, Zexel/Valeo ] See: Service and Repair.
‹› 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.
‹› If drive plate has already been replaced once in customer service and was bonded at that time using sealing compound D 154 102 A1, it may be
joined so securely to the compressor shaft that it can no longer be pressed off. Refer to => [ Belt Pulley, Zexel/Valeo ] See: Service and Repair, in
this case the entire compressor must be replaced.
4
Circlip
‹› Replace
‹› Install on proper side, beveled insertion edge - A - faces away from A/C compressor (install flat side facing the A/C compressor)
‹› When installing circlip, note that it cannot be bent open more than is necessary for installation.
5
Belt pulley
‹› Clean A/C compressor flange before sliding on pulley.
6
A/C Compressor
‹› Different versions may be installed, depending on engine version and country version of vehicle.
‹› Clean A/C compressor flange before sliding on pulley.
