Belt Pulley, Denso Version 3

Belt Pulley, Denso Version 3

• If overload protection of pulley triggers, check the A/C compressor for ease of motion before replacing the pulley. If the A/C compressor creates friction, replace it completely.

• Perform preliminary work as for removing belt pulley. Refer to=> [ Preparation ] Belt Pulley, Denso Version 1.

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

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






Removing

- Remove the cap - A -.






- Hold the A/C compressor input shaft - B - for example, with a standard Allen wrench (7 mm) and turn the drive plate - C - together with the pulley - E - in the direction of the - arrow -.

• The torque to drive the A/C compressor is transferred to the drive plate - C - via the threaded connection. If, while the A/C compressor is working, the drive plate - C - was attached to the A/C compressor shaft so tight, that it cannot be loosened (the 7 mm Allen wrench - B - cannot transmit the necessary torque) then the A/C compressor must be replaced.

- Remove drive plate - C -.

- Remove circlip - A -.






- Remove pulley - B -.

Installing

• Replace circlip - A -.

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

When installing 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).

- Clean the compressor shaft thread before 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.

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

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

- Press the drive plate rubber element - C - far enough into the pulley - E - until the drive plate - C - until it contacts A/C compressor shaft - B -.






- Install the drive plate - C - onto the compressor shaft - B - by rotating it opposite the direction of arrow - arrow -.

- Hold the compressor input shaft - B - for example, with a standard Allen wrench (7 mm) and turn the drive plate - C - together with the pulley - E - in the direction of the arrow - arrow -.
