Description of Change: A triangular-shaped retainer is used to more securely fasten the two air inlet pipes in the turbocharger compressor housings on the above engines. The shape of the retainers allows more contact with the flange on the pipes and minimizes the possibility of the pipe vibrating loose. Formerly, a washer was used at each location of the retainer.
Adaptable To: The new retainers can be used as direct replacements for the former washers on all the applicable engines. There are two threaded bosses on each compressor housing. Install one retainer in the upper boss of each compressor housing.
Typical location of new retainers on compressor inlet pipes.
