Exhibit 31.2

                                  CERTIFICATION

I, Dale A. Schnittjer, Interim Chief Financial Officer, Vice President and
Controller of Teledyne Technologies Incorporated (the "registrant"), certify
that:

1.      I have reviewed this quarterly report on Form 10-Q for the quarterly
        period ended June 29, 2003 of Teledyne Technologies Incorporated;

2.      Based on my knowledge, this quarterly report does not contain any untrue
        statement of a material fact or omit to state a material fact necessary
        to make the statements made, in light of the circumstances under which
        such statements were made, not misleading with respect to the period
        covered by this quarterly report;

3.      Based on my knowledge, the financial statements, and other financial
        information included in this quarterly report, fairly present in all
        material respects the financial condition, results of operations and
        cash flows of the registrant as of, and for, the periods presented in
        this quarterly report;

4.      The registrant's other certifying officer and I are responsible for
        establishing and maintaining disclosure controls and procedures (as
        defined in Exchange Act Rules 13a--15(e) and 15d--15(e)) for the
        registrant and have:

        a)      Designed such disclosure controls and procedures, or caused such
                disclaimed controls to be designed under our supervision, to
                ensure that material information relating to the registrant,
                including its consolidated subsidiaries, is made known to us by
                others within those entities, particularly during the period in
                which this quarterly report is prepared;

        b)      Evaluated the effectiveness of the registrant's disclosure
                controls and procedures and presented in this report our
                conclusions about the effectiveness of the disclosure controls
                and procedures as of the end of the period covered by two
                reports based on such evaluation; and

        c)      Disclosed in this report any change in the registrant's internal
                control over financial reporting that occurred during the
                registrant's most recent fiscal quarter that has materially
                affected, or is reasonably likely to materially affect, the
                registrant's internal control over financial reporting; and

5.      The registrant's other certifying officer and I have disclosed, based on
        our most recent evaluation of internal control over financial reporting,
        to the registrant's auditors and the audit committee of registrant's
        board of directors:

        a)      all significant deficiencies and material weaknesses in the
                design or operation of internal control over financial reporting
                which are reasonably likely to adversely affect the registrant's
                ability to record, process, summarize and report financial
                information; and

        b)      any fraud, whether or not material, that involves management or
                other employees who have a significant role in the registrant's
                internal controls
