Series 60 – Section 6.2 Air Cleaner

Section 6.2
Air Cleaner

Air cleaners are designed to remove foreign matter from the air and pass the required volume of air for proper combustion. Manufacturers guidelines should be consulted to maintain efficient operation for a reasonable period of time before requiring service. ‪

The importance of keeping dust and grit-laden air out of the engine cannot be overemphasized, since clean air is essential to satisfactory engine operation and long engine life. Should dust in the air supply enter the engine, it would be carried into the cylinders and, due to its abrasive properties, cause premature wear of the moving parts. Dirt, which is allowed to build up in the air cleaner passages, will eventually restrict the air supply to the engine and result in heavy carbon deposits on the valves and pistons due to incomplete combustion. The air cleaner must have a capacity large enough to retain the material separated from the air to permit operation for a reasonable length of time before cleaning is required.‪


Detroit Diesel is aware of attempts to use air cleaner elements made of foam or fabric batting material soaked with a sticky substance to improve dirt-holding capability. In some installations this substance has been found to transfer from the filter media, coating the inside surfaces of air ducts and engine air inlet systems, blowers, and air boxes. The result has been reduced engine performance and a change in engine operating conditions.‪

Only oil bath type and dry paper element type air cleaners are recommended for use on all Detroit Diesel Series 60 engines. Alternate types of air filtration systems may be available in the after-market. Detroit Diesel does not recommend use or extend warranty to cover damage or malfunction of engine components as a result of usage on Detroit Diesel Series 60 engines.‪

If a foam or fabric air cleaner element soaked with a sticky, dirt-holding substance was previously installed, check for the presence of coated engine components. Remove and clean coated engine components as required. Refer to "1.1.2 Removal and Disassembly of Engine from the Vehicle" .‪
