              Post-Effective Amendment No. 1 to Registration Statement on
              Form S-3, File  No. 333-68652

Ladies and Gentlemen:

     Pursuant to Rule 477 under the Securities Act of 1933, as amended, SPX
Corporation (the "Company") hereby requests that its Post-Effective Amendment
No. 1 to the Registration Statement on Form S-3 (File No. 333-68652), filed on
April 4, 2002 (the "Registration Statement"), be withdrawn, with such
application to be approved effective as of the date hereof or at the earliest
practical date thereafter.

     Given our discussions with the Securities and Exchange Commission, the
Company is withdrawing the above-referenced Post-Effective Amendment No. 1 to
the Registration Statement. The Company confirms that no securities have been
issued or sold pursuant to the Post-Effective Amendment No. 1 to the
Registration Statement.

                                 Very truly yours,

                                 SPX Corporation
