General Maintenance & Service Tips
5 Don't Ignore a Worn or Damaged Gasket in the Housing If your air cleaner has a cover gasket, replace it with a new one. Always check to be housing and that the gasket is not worn.

Contaminants smaller than we can see will cause damage to a diesel engine. If the housing is not going to be reassem- bled immediately, cover the opening.
