Teledyne Technologies Incorporated
12333 West Olympic Boulevard
Los Angeles, California  90064

Ladies and Gentlemen:

         We are counsel to Teledyne  Technologies  Incorporated  (the "Company")
and we have acted as counsel for the Company in connection  with the preparation
of the  Registration  Statement  on Form S-8 to be filed by the Company with the
Securities and Exchange Commission for the registration under the Securities Act
of 1933,  as amended,  of 2,400,000  shares of the Company's  common stock,  par
value $.01 per share (the "Shares"), which are to be issued from time to time to
certain  employees of the Company and its affiliates  and certain  non-employees
who render significant  services to the Company and its affiliates in connection
with the  Teledyne  Technologies  Incorporated  2002 Stock  Incentive  Plan (the
"Plan").

         We have examined the originals,  certified  copies or copies  otherwise
identified to our  satisfaction  as being true copies of the Plan and such other
documents  as we have  deemed  necessary  or  appropriate  for  purposes of this
opinion.

         Based on the foregoing, we are of the opinion that the Shares have been
duly and validly authorized and reserved for issuance, and that the Shares, when
issued under the terms of the Plan,  will be legally and validly  issued,  fully
paid and nonassessable.

         We hereby  consent to the filing of this  opinion as Exhibit 5.1 to the
Registration Statement.

                                                  Very truly yours,



                                                  /s/ Kirkpatrick & Lockhart LLP
