 Amendment No. 6 to Schedule 13D

     This Amendment No. 6 amends and supplements the Schedule 13D originally
filed by Unitrin, Inc., Trinity Universal Insurance Company and United Insurance
Company of America, dated November 3, 1997, as amended by Amendment No. 1, dated
February 1, 2001, Amendment No. 2, dated March 15, 2001, Amendment No. 3, dated
June 8, 2001, Amendment No. 4, dated July 13, 2001, and Amendment No. 5 dated
March 8, 2002. Terms used herein and not otherwise defined have the meanings
given such terms in the original Schedule 13D, dated November 3, 1997.

Item 1.  Security and Issuer

     The class of equity securities to which this Schedule 13D relates is the
common stock, par value $0.01 per share (the "Common Stock"), of UNOVA, Inc., a
Delaware corporation (the "Issuer"). The principal executive offices of the
Issuer are located at 21900 Burbank Boulevard, Woodland Hills, California 91367.

Item 2.  Identity and Background

     For information concerning the directors and executive officers of Unitrin,
Trinity, and United, see Schedules UNIT, T, and U, respectively to this
Amendment. All persons listed on such Schedules are U.S. citizens.

     No filing person has been convicted in any criminal proceeding (excluding
traffic violations or similar misdemeanors) during the past five years; nor, to
the best knowledge and belief of the filing persons, has anyone listed in the
attached Schedules been convicted in such proceedings.

     To the best knowledge and belief of the filing persons, during the past
five years no filing person nor anyone listed on the attached Schedules was a
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws of finding any
violation with respect to such laws.

Item 3.  Source and Amount of Funds or Other Consideration

     On June 28, 2002, United transferred by dividend to Unitrin 6,946,315
shares of Common Stock, representing all of United's holdings of the Issuer's
Common Stock. United is a wholly owned subsidiary of Unitrin.

Item 4.  Purpose of Transaction

     In connection with Unitrin's investment in the Issuer and participation in
the Issuer's financing arrangements described in Amendment No. 4 to Schedule
13D, Unitrin may consider, make proposals with respect to, and/or enter into
discussions regarding, one or more of the transactions and events specified in
clauses (a) through (j) of Item 4 of Schedule 13D including transactions
involving additional debt or equity financing of the Issuer. There can be no
assurance that Unitrin will take any such actions or that, if taken, any such
actions will be consummated or result in any transaction of the Issuer's
securities.

Item 5.  Interest in Securities of the Issuer



                                                                     Page 6 of 7

     As described in Item 3 above, United transferred by dividend to Unitrin
6,946,315 shares of Common Stock, representing all of United's holdings of the
Issuer's Common Stock on June 28, 2002. Prior to this transaction, Unitrin
beneficially owned such shares of Common Stock indirectly through United.
Accordingly, this transaction represents only a change in the form of Unitrin's
beneficial ownership interest in the subject shares of Issuer's Common Stock
from indirect to direct.

     As indicated on the cover pages, Unitrin beneficially owns 12,657,764
shares of Common Stock over which it has (i) sole voting and dispositive power
with respect to 6,946,315 shares of the Common Stock by virtue of its direct
ownership of such shares, and (ii) shared voting and dispositive power with
respect to 5,711,449 shares of Common Stock by virtue of the direct ownership of
such shares by its wholly owned subsidiary Trinity.

     As indicated on the cover pages, Trinity beneficially owns 5,711,449 shares
of Common Stock over which it has shared voting and dispositive power, and such
beneficial ownership is attributable to Trinity's direct ownership of such
number of shares of Common Stock.

     As indicated on the cover pages, United no longer beneficially owns any
shares of Common Stock.

     Except as described in this Amendment No. 6 to Schedule 13D, to the best
knowledge and belief of the filing persons, during the past sixty (60) days no
filing person nor anyone listed in the attached Schedules has entered into any
transactions involving the Issuer's Common Stock. To the best knowledge and
belief of the filing persons, no one listed on the attached Schedules
beneficially owns shares of the Issuer's Common Stock.

                                    SIGNATURE

     After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
