Electrical Connector Passage Sleeve

Specification: 14-16 mm

Special Tools

NOTE:

Orientate the alignment tab inside the passage sleeve with the
slot in the electrical connector of the control solenoid valve
assembly. Push the sleeve straight into the case bore and
connector. Do NOT rotate the sleeve at any time. Ensure the
sleeve is fully seated into the case. When the sleeve is properly
installed, the distance from the case surface to the end of the
sleeve should be 14-16 mm. Even though the correct electrical
connections may still be maintained, failure to ensure proper
installation of the sleeve may result in a fluid leak around the
sleeve lip seal and into the sleeve cavity.
