Turbo Adapter Sleeve for Caterpillar 3406A & 3406B Aftercooled Engines

This adapter sleeve allows you to put a modern CAT/BorgWarner turbo on aftercooled 3406 Caterpillar engines.  The sleeve goes into the compressor discharge outlet to reduce down the size so that that factory cross over pipe fits inside.  Often times you WILL need to cut down the size of your cross over tube as the new turbo compressor cover sticks out further.  

Includes O-rings, ready for installation!
