No. on auxiliary component bracket (06F 903 143 E/F)
Removing
- Remove generator.
- Loosen A/C compressor, unscrew hex-bolts - 6 -. Remove A/C compressor from auxiliary component bracket and secure to body with appropriate material (e.g. welding wire) => [ Securing A/C compressor to body ]
- Remove bolts - 1 - through - 4 -, - 7 - and - 8 - and remove auxiliary component bracket - 10 - from cylinder block.
Installing
• Always observe tightening torque of mounting bolts:
- Tighten hex collar bolt item - 1 - (fitting hole), - 7 - (fitting hole), - 4 -, - 8 -, - 3 - and - 2 - in succession.
Securing A/C compressor to body
If A/C compressor is removed and refrigerant circuit not opened, A/C compressor must be secure to body using appropriate material, a welding wire for example.
Ensure refrigerant hoses remain on A/C compressor without tension for this.
Ribbed Belt Routing
1. Tensioning roller
2. Ribbed belt pulley - generator
3. Ribbed belt pulley - A/C compressor
4. Ribbed belt
5. Ribbed belt pulley - crankshaft
• When installing the belt ensure it is correctly seated in the ribbed belt pulley.
• Last, install ribbed belt over ribbed belt pulley of A/C compressor.
