Item 1.         Security and Issuer
                This Amendment No. 10 to Schedule 13D on the Common Stock of
Navistar International Corporation (the "Issuer") is being filed on behalf of
the undersigned to amend the Schedule 13D, as amended (the "Schedule 13D")
which was originally filed on March 14, 2000.  Unless otherwise indicated, all
capitalized terms used herein but not defined herein shall have the same
meanings as set forth in the Schedule 13D.

Item 2.         Identity and Background
This statement is being filed by Mario J. Gabelli ("Mario
Gabelli") and various entities which he
directly or indirectly controls or for which he acts as chief investment
officer.  These entities, except for Lynch Corporation ("Lynch") and Lynch
Interactive Corporation ("Interactive"), engage in various aspects of the
securities business, primarily as investment adviser to various institutional
and individual clients, including registered investment companies and pension
plans, and as general partner of various private investment partnerships.
Certain of these entities may also make investments for their own accounts.
                The foregoing persons in the aggregate often own beneficially more
than 5% of a class of a particular issuer.  Although several of the foregoing
persons are treated as institutional investors for purposes of reporting their
beneficial ownership on the short-form Schedule 13G, the holdings of those who
do not qualify as institutional investors may exceed the 1% threshold presented
for filing on Schedule 13G or implementation of their investment philosophy may
from time to time require action which could be viewed as not completely
passive.  In order to avoid any question as to whether their beneficial
ownership is being reported on the proper form and in order to provide greater
investment flexibility and administrative uniformity, these persons have
decided to file their beneficial ownership reports on the more detailed
Schedule 13D form rather than on the short-form Schedule 13G and thereby to
provide more expansive disclosure than may be necessary.
                (a), (b) and (c) - This statement is being filed by one or more of
the following persons: GGCP, Inc.  formerly known as Gabelli Group Capital
Partners, Inc. ("GGCP"), GAMCO Investors, Inc. formerly known as Gabelli Asset
Management Inc. ("GBL"), Gabelli Funds, LLC ("Gabelli Funds"), GAMCO Asset
