Removing and installing pulley, "“Denso”" air conditioner compressor, version "“2”" — AUDI

🧭 Before you start

Fits: Audi TT Mk2 (8J, 2006–2014)

Don't miss

• Renew circlip (A).
• Ensure that circlip (A) is fitted correctly. Bevelled side (C) faces away from air conditioner compressor (flat side faces compressor).
• Thread of new drive plate has been lubricated at factory with a pre-determined amount of a specific grease.
• Before installing drive plate, coat rubber elements (D) slightly with lubricant (e.g. tyre fitting paste or soap solution).

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. Remove cap (A).
2. Hold drive shaft (B) of air conditioner compressor using e.g. a standard hexagon socket wrench (7 mm) and turn drive plate (C) with pulley (E) in direction of (arrow). [Note: The torque for driving the air conditioner compressor is applied to the compressor shaft via the threaded connection between the drive plate (C) and the compressor shaft. If the drive plate (C) has become so firmly attached to the air conditioner compressor shaft that it can no longer be loosened (the 7 mm hexagon socket wrench (B) can no longer transmit the necessary torque), the compressor must be renewed.]
3. Detach drive plate (C).
4. Remove circlip (A).
5. Detach pulley (B). [Note: Renew circlip (A).]

6. Install pulley (B).
7. Ensure that circlip (A) is fitted correctly. Bevelled side (C) faces away from air conditioner compressor (flat side faces compressor).
8. Clean thread of compressor shaft before screwing on drive plate. [Note: Thread of new drive plate has been lubricated at factory with a pre-determined amount of a specific grease.]
9. Before installing drive plate, coat rubber elements (D) slightly with lubricant (e.g. tyre fitting paste or soap solution).
10. Insert rubber elements (D) into pulley (B) as shown.
11. Press rubber element of drive plate (C) into pulley (E) until drive plate (C) makes contact with thread of air conditioner compressor shaft (B).
12. Screw drive plate (C) onto compressor shaft (B) by turning in opposite direction of (arrow).
13. Hold drive shaft (B) of air conditioner compressor using e.g. a standard hexagon socket wrench (7 mm), turn drive plate (C) with pulley (E) in opposite direction of (arrow) and tighten to torque (30 Nm). — 30 Nm (22 lb-ft)
