### Removal Procedure

Important: A small amount of oil weepage through the front seal of the supercharger assembly, behind the pulley is a normal condition. A buildup of belt dust and/or airborne dust can adhere to the thin oil film, which causes the oil weepage to appear worse than it really is. The supercharger assembly should not be replaced due to the weepage described. However if the supercharger oil is visually dripping or puddling from the supercharger front seal, the supercharger assembly will need to be replaced.

1. Remove the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement .
2. To prevent contamination of the supercharger oil, clean the area around the oil fill plug before removing.
3. Remove the oil plug.
4. The oil level should be maintained to the bottom of the threads in the inspection hole.

### Installation Procedure

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Install the oil plug and ensure the o-ring is in place on the plug.

Tighten
Tighten the oil plug to 10 N·m (89 lb in).

2. Install the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement .
