        B0068HS Pinch
        B006964 Pull

        Pinch the retainer of the urea tube connector, and then pull the urea tube connector off of the No. 1 urea tube with heater.

        Note


        • If there is any solidified urea solution (white solids) on the connection area, clean the solids off with a damp cloth, etc., before disconnecting the connector.

        • Be sure to disconnect the urea tube connector by hand.

        • Check for foreign matter in the urea pump and around the urea tube connector. Clean if necessary. Foreign matter may damage the O-ring or cause leaks in the seal between the urea pump and urea tube connector.

        • Put the urea pump and urea tube connector ends in plastic bags to prevent damage and foreign matter contamination.
