Amendment No. 4 to Schedule 13D

     This Amendment No. 4 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, and Amendment No. 3, dated June 8, 2001. 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 $.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 and for information concerning the directors
and executive officers of Union National Life Insurance Company, a
Louisiana corporation ("Union"), 8282 Goodwood Boulevard, Baton Rouge,
Louisiana 70806, see Schedules UNIT, T, U, and UNL, 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 or finding any violation with respect to such laws.

Item 4.  Purpose of Transaction

Item 4 of the original Schedule 13D is hereby restated in its entirety as
follows:

     On July 12, 2001, the Issuer entered into a loan agreement (the "Loan
Agreement") by and among the Issuer, certain of its subsidiaries, and
Special Value Investment Management, LLC, as agent (the "Agent") for the
several lenders under the Loan Agreement. The Loan Agreement provides for
the Agent to arrange term loan financing, from such lenders as may be from
time to time parties to the Loan Agreement, in an aggregate amount not to
exceed $75 million. Borrowings under the Loan Agreement are due and payable
on July 11, 2004. The Loan Agreement contains customary negative covenants
regarding, among other things, mergers, consolidations, and sales; capital
expenditures; limitations on indebtedness; investments; liens; and
dividends and other restricted payments. The Loan Agreement also contains
financial covenants relating to the net worth, fixed charge coverage ratio
and earnings before interest, taxes, depreciation, and amortization of the
Issuer.

     In connection with the entry of the Issuer into the Loan Agreement,
Unitrin has caused each of Trinity, United and The Reliable Life Insurance
Company, a Missouri corporation and wholly owned subsidiary of United
("Reliable") (Trinity, United and Reliable being sometimes referred to
herein collectively as the "Assignees"), to enter into assignment and
acceptance agreements (each an "Agreement"), in each case with Tennenbaum
Securities, LLC (the "Assignor"). The Agreements provide that the Assignor
assign to the Assignees part of the rights and obligations of the Assignor
under the Loan Agreement on the terms and subject to the conditions set
forth in the Agreements. Under the Agreements, Trinity has been assigned
and has accepted a $15 million dollar interest under the Loan Agreement;
United has been assigned and has accepted a $15 million dollar interest;
and Reliable has been assigned and has accepted a $1.5 million dollar
interest.

     In connection with Unitrin's participation in the Issuer's financing
arrangements and Unitrin's investment in the Issuer, 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 in the Issuer's securities.




                                                               Page 7 of 12

Item 5.  Interest in Securities of the Issuer

     Other than the transfer of 1,495,327 shares of Common Stock by Trinity
to Union, a wholly owned subsidiary of United, none of Unitrin, Trinity,
United or Union has acquired or disposed of any shares of the Issuer's
Common Stock since November 3, 1997, the date of the original Schedule 13D.
However, the collective percentage ownership by Unitrin, Trinity, United
and Union (the "Unitrin Ownership Percentage") of the Issuer's Common Stock
has decreased as the result of a change in the outstanding number of shares
of the Issuer's Common Stock since November 3, 1997. The result of this
change is that the Unitrin Ownership Percentage in the Issuer's Common
Stock has decreased from 23.2% as reported in the original Schedule 13D to
22.3% as of the date of this Amendment.

     To the best knowledge and belief of the filing persons, during the
past sixty (60) days no filing person nor anyone listed on 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.

Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect
to Securities of the Issuer

     As more fully described in Item 4 above, on July 12, 2001, in
connection with the entry by the Issuer into the Loan Agreement by and
among the Issuer, certain of its subsidiaries, and Special Value Investment
Management, LLC, as agent for the several lenders under the Loan Agreement,
Unitrin caused each of Trinity, United and Reliable to enter into
assignment and acceptance agreements, in each case with Tennenbaum
Securities, LLC.
