PARTS NEEDED
No parts needed for this program
ACTION REQUIRED
1. Remove the 208-9064 Cover and 226?2779 Element from the air cleaner.
2. If necessary, dry out the element and metal housing.
3. Inspect the turbocharger compressor housing for rust before removing the turbocharger compressor housing. If the housing has rust remove the compressor housing and remove the rust per the appropriate rust removal procedure below.
4. Reinstall turbocharger compressor after rust removal.
5. Reinstall air cleaner.
Rust Removal Procedure:
Definition of types of rust:
- Flash/surface rust - Rust that can be removed with an oiled towel.
- Light rust - No scaling or pitting and cannot be removed with an oiled towel.
- Heavy rust - Scale and pitting.
Removal of rust:
- Flash rust can be removed with penetrating oil such as Kroil or WD40.
- Light rust can be removed with a wire brush. Apply penetrating oil to the surface to prevent future surface rust.
- Heavy rust can be removed with a wire brush to remove the rust but it must also be neutralized with a neutralizing solution such as MP-7. The MP-7 neutralizing solution should be sprayed on until the surface is "wet". Let it stand for 10 minutes to neutralize the surface. Re-spray the surface during this 10 minute period to keep the surface "wet". Flush the surface with water after the 10 minute
neutralization period. Reference SEBF8018 for reuse of the turbocharger compressor housing. Apply penetrating oil to the surface to prevent future surface rust.
