Subject: Note Change of Ports on Certain Bendix® Tu-Flo® 550 and
Tu-Flo® 750 Compressors used for International Engines
As a product improvement, Bendix Commercial Vehicle Systems has phased
in coolant and/or oil port changes on certain Bendix compressors used on
International engines. See below for details of which engines are affected and
the adapter kit or plug that may be required when servicing these compressors.
Flange Mount
During the last quarter of 2004, Bendix changed the coolant ports in the head of
the compressors listed below, from two M18 ports and one M14 port, to a standard
of three M18 ports. The port which is affected by this change is typically plugged
in this application. When ordering a service replacement, you will not be able to
re-use the original plug. Please order an M18 coolant port plug as needed.

International VT365 engines using Bendix® Tu-Flo® 550 base-mount compressors
(part number 5009328) are also affected by the change in the third water port
explained above. For this engine application, the third water port is typically not
plugged so Bendix is making an M14 to M18 adapter available as part of a kit for
ease of installation.
In addition, part number 5009328 is being superseded, during the second quarter
of 2005, by part number 5015318. The replacement compressor varies by one
oil port, featuring an M10 oil port instead of the original M8 oil port. To assist
installation, the adapter kit also includes an M10 to M8 adapter.
