The rattle could be caused by several things, including:
* Loose or worn bearings: This is a common cause and often requires a complete rebuild or replacement of the supercharger.
* Damaged impeller: A chipped or bent impeller will cause imbalance and rattling.
* Loose or damaged internal components: Various internal components, such as shafts, gears, or rotors, could be damaged and rattling.
* Loose fasteners: While less likely to cause a significant rattle, loose bolts or screws could contribute to the noise.
* Foreign object in the snout: Something might have gotten into the supercharger's intake.
There is no single diagram that covers all supercharger types. Superchargers vary widely in design depending on the manufacturer and application (roots-type, centrifugal, screw-type, etc.). A diagram would be specific to the *exact* make and model of your supercharger.
What you SHOULD do:
1. Stop driving immediately: Continued operation with a rattling supercharger could cause catastrophic failure.
2. Consult your vehicle's service manual: This may provide some basic troubleshooting information or contact information for authorized repair facilities.
3. Contact a qualified mechanic or supercharger specialist: They have the expertise, tools, and diagnostic equipment to properly identify and repair the problem. Explain the rattling sound and the location precisely.
4. Prepare for a potentially expensive repair: Supercharger repairs are often costly, as they frequently require specialized parts and labor.
Trying to fix this yourself is strongly discouraged unless you have extensive experience with superchargers and possess the necessary specialized tools and equipment. Improper repair can lead to further damage and potentially dangerous operating conditions. The cost of a professional repair is likely less than the cost of replacing a completely destroyed supercharger due to a failed DIY attempt.
