Description of Change: This article supersedes the article with the same title on Page 1 of the September 1991 issue of Truck Engine News.
The 7E5888 Fuel Injection Pump Housing (used on 1991 engines) is service replacement for pre 1991 fuel injection pump housings on the above 3406B Engines. The 7E5888 Fuel Injection Pump Housing has a larger diameter camshaft bearing bore than the pre 1991 pump housings. Therefore, thicker bearings are required (to work with the smaller diameter pump camshaft) when using the 1991 pump housing to replace a pre 1991 pump housing.
