Leon Mk2
Pulley: Replacing (compressor make „Sanden“) |
Note
t | Follow the instructions for the removal of the pulley in the compressor make „Denso“, version „1“; these instructions are also valid for this compressor → Chapter. |
t | Carry out preparation work in the same way as for the removal of the pulley in the compressor make „Denso“, version „1“ → Anchor. |
t | There are different versions of the air conditioner compressor pulley. Version „1“ of the pulley is fitted on compressors with part number 1K0 820 803 up to index „Q“; compressors with part number 1K0 820 803 from index „S“ onwards are fitted with version „2“ of the pulley (gradual introduction from December 2005 onwards) → Electronic spare parts catalogue. |
Renewing pulley (type „1“) |
1 - | Conical hexagon bolt |
q | Replace: |
q | To release and tighten the hexagonal bolt, the pulley should be held with a strap wrench |
q | Clean the thread of the hexagonal bolt and the thread of the compressor axle to remove fixing agents from old threads before bolting |
q | Fit the hexagonal bolt prepared with thread fixing agent (e.g. with D 000 600 A2) → Parts catalogue |
q | Tightening torque: 25 Nm |
2 - | Bolt. |
q | To release and tighten the bolt, the pulley should be held with a strap wrench |
q | Tightening torque: 4.5 Nm |
3 - | Drive plate |
q | The overload rubber element acts in case of excess torque (in case the compressor becomes difficult to operate) and the pulley moves freely without operating the compressor |
q | With a rubber element to separate the pulley from the compressor operation axle, absorb vibrations and noise. |
4 - | Plate |
5 - | Circlip |
q | Replace: |
q | Install in correct position. The inlet chamfer -A- shows away from the compressor (flat side to the compressor) |
q | Take special care when fitting the circlip that it is not bent any more than is necessary for fitting |
6 - | Pulley |
q | Clean the compressor bracket before fitting the pulley |
7 - | Supercharger |
q | Depending on the engine version and on the country there are different versions → Parts catalogue |
q | Clean the compressor bracket before fitting the pulley |
Note
|
1 - | Conical hexagon bolt |
Note
A plastic cap may be fitted additionally to protect thread of compressor shaft (cap is not shown in illustration). |
q | Hold pulley using a commercially available strap wrench (fabric strap) when loosening or tightening hexagon nut |
q | Before installing, clean residual locking fluid off thread of hexagon nut and thread of air conditioner compressor shaft |
q | Apply locking fluid (e.g. D 000 600 A2) when fitting hexagon nut / bolt → Electronic parts catalogue |
q | Tightening torque for hexagon nut: 25 Nm |
2 - | Bolt. |
q | To slacken and tighten bolts, hold pulley in position with a commercially available strap wrench (with fabric strap). |
q | Tightening torque: 12 Nm |
q | Before screwing in, remove old locking fluid from bolt threads and threads of pulley |
q | Apply locking fluid (e.g. D 000 600 A2) when fitting bolts → Electronic parts catalogue |
3 - | Drive plate |
q | With overload protection device (attachment of spring elements); triggered if torque is too great (e.g. if air conditioner compressor cannot rotate freely) causing pulley to free-wheel without driving air conditioner compressor |
q | Spring elements of drive plate dampen vibrations and reduce noise |
4 - | Circlip |
q | Replace: |
q | Do not reverse when installing; chamfer -A- faces away from air conditioning compressor (flat side towards air conditioner compressor) |
q | When fitting circlip, take care not to bend it open more than necessary. |
5 - | Pulley |
q | Air conditioner compressor flange; clean before pushing on pulley |
q | With rubber elements -B- and threaded plates -C- for decoupling pulley from drive shaft of air conditioner compressor (the rubber elements dampen vibrations and reduce noise) |
Note
Depending on version, threaded plates -C- may also be linked via a ring. |
6 - | Air conditioning compressor |
q | Different versions may be fitted, depending on type of engine and country-specific version of vehicle → Electronic parts catalogue |
q | Air conditioner compressor flange; clean before pushing on pulley |
