Denso A/C Compressor (Version 1)

Denso A/C Compressor (Version 1)

• Observe notes on replacing belt pulley. Refer to => [ Belt Pulley, Denso A/C Compressor, Version 1 ] Belt Pulley, Denso A/C Compressor, Version 1.

• Perform preliminary work as for removing belt pulley. Refer to=> [ A/C Compressor Belt Pulley, Replacement ] A/C Compressor Belt Pulley, Replacement.

• Belt pulley is made of plastic and is sensitive to impact, therefore handle it with special care.

• If overload safeguard of drive plate - C - has triggered, drive plate can be pried off from belt pulley - D - after removing circlip - A -






• To optimize noise reduction, a circlip - A - with a rubber disc vulcanized on it is installed. Refer to=> [ Belt Pulley, Denso A/C Compressor, Version 1 ] Belt Pulley, Denso A/C Compressor, Version 1 and Electronic Parts Catalog. This rubber disc can reduce a clapping (castanet-like) noise which occurs especially at belt pulley in vehicles with Diesel engine in A/C system operating mode "Econ" ("AC off") (the noise is almost inaudible with A/C system operating at full output).

Removal

- Using a small screwdriver or needle-nose pliers, carefully remove circlip - A - (with rubber disc vulcanized on to it). Refer to=> [ Belt Pulley, Denso A/C Compressor, Version 1 ] Belt Pulley, Denso A/C Compressor, Version 1; take extreme care not to damage belt pulley when doing this.






- Hold the A/C compressor input shaft - B - securely with a standard socket wrench and turn drive plate - C - with pulley - D - in direction of arrow - E - (tightening torque 35 Nm).

- Remove drive plate - C -.

- Remove circlip - A -.






- Remove pulley - B -.

Installation

• Replace circlip - A -.






Clean the A/C compressor flange before sliding on the belt pulley.

When installing the circlip - A -, note that it cannot be bent open more than is necessary for installation.

- Install belt pulley - B -.

- Insert circlip - A - on correct side, the side with beveled insertion edge - C - faces away from A/C compressor (install flat side facing compressor).

- Insert rubber element - D - in belt pulley - B - according to illustration.

- When installing drive plate, coat rubber element - D - lightly e.g. with tire mounting paste or soap solution (as sliding compound).

- Insert the drive plate - C - far enough into rubber elements - D - (see upper illustration) until it contacts A/C compressor shaft - B -.






- Install the drive plate - C - on the compressor shaft - B - by rotating it in the direction of the arrow - F -.






- Tighten drive plate - C - (above pulley - D -) to 35 Nm by turning with a standard band wrench (with webbing) in direction of arrow - F -, hold compressor shaft - B - with a standard socket wrench.

- Install circlip - A - (with rubber disc vulcanized on).
