Pulley, Removing From Compressor and Reinstalling

Pulley, Removing From Compressor And Reinstalling

NOTE:
- If overload protection of pulley triggers, check compressor for ease of motion before replacing the pulley. If compressor creates friction, replace it completely.
- To remove pulley, it depends on engine version if it is necessary to remove compressor from engine.
- The compressor can be removed and installed from the bracket without opening the refrigerant lines.
- Mark direction of rotation of ribbed belt using chalk or felt-tip marker before removing. Reversing the direction of rotation of a run-in belt can destroy the belt.
- Different compressors are installed, depending on engine and country version (installed on right or left at engine, 6-cyl. gasoline or diesel engine, cold or hot country).

Removing
- Remove noise insulation.
- Bring the lock carrier into service position.
- Release tension on ribbed belt and remove it.







- Remove bolt -A- (tightening torque 20 Nm).

NOTE:
- If pulley cannot be removed with compressor installed, remove compressor from engine.
- To loosen and tighten bolt -A-, counterhold it at drive plate -B- using a commercially available pin wrench -C- (pin diameter 5.0 mm).
- Bolt -A- must be replaced (because of locking compound).







- Carefully pry off drive plate -A- using 2 screwdrivers -B-.

NOTE:
- Make sure that the collar for pulley -C- is not damaged when prying off drive plate -A-.
- There are different versions of pulley -C- and drive plate -A-, therefore note the exact dimensions.







- Remove securing ring -A-.
- Remove pulley -B-.

Installing
- Installation is reverse of removal.

NOTE:
- Replace securing ring -A-.
- When installing securing ring -A-, make sure it is not bent up more than is necessary for installation.
- Insert securing ring -A- on proper side, the side with installing slopes -C- faces away from compressor (install flat side facing compressor).







- Ensure proper seating of securing ring in groove on compressor flange.
- Clean compressor flange before installing the pulley, as pulley must be able to be installed easily. (Installing must be possible without excessive force).
