NO SUSPECT VALVES WERE SUPPLIED AS SERVICE PARTS. NO SUSPECT VALVES WERE SUPPLIED AS CAMPAIGN PARTS.
A quantity of known good proportioner valves with the same machine marks as those being replaced, but with date codes higher than the suspect range,
were used to provide campaign parts. Use of valves that look the same as those being replaced has caused confusion at some dealerships.
To eliminate this confusion, and to avoid unnecessary replacement of good valves in the future, the following is recommended:
^
Use any service parts which may be in stock. They are all good valves.
^
Valves received in campaign parts packages, regardless of their machine marks, are okay. Use them on campaign cars as needed.
^
Be sure to install campaign identification labels in each car serviced, to avoid unnecessary future replacement of good valves.
^
Do not be concerned with the campaign service valves that you may have already installed. They are all good valves.
