Denso A/C Compressor Belt Pulley - Version 1

Denso A/C Compressor Belt Pulley - Version 1

• If the drive plate overload protection activates, check the A/C compressor for ease of movement before replacing the belt pulley. If the A/C compressor creates friction, replace it completely.

• The A/C compressor can be removed from the sub-assembly bracket and installed again without opening the refrigerant lines.

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

• If the overload protection of the drive plate - C - activates, rotate the belt pulley - E - using the outer part of the drive plate - C - so that the A/C compressor shaft - B - and the hexagon head on the drive plate - D - (inner part of the drive plate - C -) do not rotate.






• The belt pulley including the drive plate and sealing cap is available as a replacement part - the parts are held together by a screw which is not needed and can be disposed of. Refer to Electronic Parts Catalog (ETKA).

• When the bolt was manufactured, a predetermined amount of a specific grease was applied to the threads of the drive plate; this amount is sufficient for bolting the drive plate to the A/C compressor shaft one time - a drive plate, which has been removed, therefore cannot be reused.

Removal






- Removing ribbed belt.

- Remove the sealing cap - A -.

- Counter-hold the input shaft - B - of the A/C compressor with a commercially available 7 mm hex wrench.

- Turn the drive plate - C - with the belt pulley - E - in the - direction of the arrow -.

- Remove the drive plate.

• The torque for driving the A/C compressor is transferred to the A/C compressor shaft via the threaded connection of the drive plate.

• If the drive plate has become so tightly attached to the A/C compressor shaft during A/C compressor operation that it cannot be loosened (the 7 mm hex wrench cannot transmit the necessary torque), the A/C compressor must be replaced.

- Remove the circlip - A -.






- Remove the belt pulley - B -.

Installation

Installation is done is reverse order, observe the following:

• Tightening specification, refer to => [ Denso A/C Compressor Belt Pulley - Version 1 Overview ] Denso A/C Compressor Belt Pulley - Version 1 Overview.

- Clean the A/C compressor input shaft before sliding on the belt pulley.

- Attach the belt pulley to the A/C compressor input shaft.

• (fitting must be possible without much force).

- Install the circlip - A - on the right side.

• The beveled insertion edge - C - faces away from the A/C compressor - install the flat side facing the A/C compressor.

- Clean the A/C compressor input shaft threads prior to mounting the drive plate.

• The thread of the new drive plate has already been greased with a specific amount of a grease by the manufacturer.

- Insert the rubber element - D - in the belt pulley - B - as shown in the figure and coat lightly with tire mounting paste or a soap solution (as a lubricant), for example.






- Insert the drive plate - C - into the rubber element until it is in contact with the input shaft - B - of the A/C compressor.

- Press the rubber element of the drive plate into the belt pulley - E - until the drive plate is in contact with the threads of the A/C compressor input shaft.

- Screw the drive plate with the belt pulley onto the A/C compressor input shaft by rotating against the - direction of the arrow - while counter-holding with a hex wrench.

- Install the ribbed belt.
