                       CUMMINS ENGINE COMPANY, INC.
                ____________________________
                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 __________________________________________
                                Unaudited
             _______________________________________________________



Note 1.  Accounting Policies:  The Consolidated Financial Statements
for the interim periods ended SeptemberMarch 26, 19992000 and September 27, 1998March 28, 1999 have
been prepared in accordance with the accounting policies described in
the Company's Annual Report to Shareholders and Form 10-K.  Management
believes the statements include all adjustments of a normal recurring
nature necessary to present fairly the results of operations for the
interim periods.  Inventory values at interim reporting dates are based
upon estimates of the annual adjustments for taking physical inventory
and for the change in cost of LIFO inventories.

Note 2.  Acquisition:  In January 1998, Cummins completed the acquisition
of the stock of Nelson Industries, Inc., for $453 million.  Nelson, a
filtration and exhaust systems manufacturer, was consolidated from the
date of its acquisition.  In accordance with APB Opinion No.16, Nelson's
net assets were recorded at fair value at the date of acquisition.  The
purchase price in excess of net assets will be amortized over 40 years.

Note 3.  Special Charges:  In the third quarter of 1998, the Company
recorded a special charge of $35 million related to a revised estimate
of product coverage cost liability primarily for extended warranty
programs.  The third quarter special charge also included $14 million
for inventory write-downs associated with the Company's restructuring
and exit activities.  This write-down relates to amounts of inventory
rendered excess or unusable due to the closing or consolidation of
facilities.  The Company has committed to these facility closures and
consolidations as part of a plan to reduce costs and improve operating
performance.

In the first quarter of 1998, the Company recorded a special charge for
product coverage expense primarily attributable to the recent
experience of higher-than-anticipated costs to repair certain
automotive engines manufactured in previous years.  The Company
believes it was necessary to make a special charge of $43 million pre-
tax to accrue for such product coverage costs expected to be incurred
in the future on these engines currently in the field.

Note 4.  Income Taxes:  Income tax expense is reported during the
interim reporting periods on the basis of the estimated annual
effective tax rate for the taxable jurisdictions in which the Company
operates.

Note 5.  Long-term Debt:  In February 1998, the Company issued $765
million face amount of notes and debentures.  Net proceeds were used to
finance the acquisition of Nelson and pay down other indebtedness
outstanding at December 31, 1997.

Note 6.  Comprehensive Income:  Comprehensive income, which includes
net income and all other nonowner changes in equity during a period, is
as follows:

Note 7.3.  Earnings per Share:  Basic earnings per share of common stock
are computed by dividing net earnings by the weighted-average number of
common shares outstanding during the period.  Diluted earnings per
share are computed by dividing net earnings by the weighted-average
number of shares, assuming the exercise of stock options.  Shares of
stock held by the employee benefits trust are not included in
outstanding shares for EPS until distributed from the trust.

Note 8.6.  Restructuring and Other Non-Recurring Charges:  In the third
quarter of 1998, the Company recorded charges of $125 million,
comprised of $100 million for costs to reduce the worldwide workforce
by approximately 1,100 people, as well as costs associated with
streamlining certain majority-owned and international joint venture
operations and $25 million for a civil penalty to be paid by the
Company as a result of an agreement reached with the U.S. Environmental
Protection Agency (EPA) regarding diesel engine emissions.  In
addition, the Company recorded special charges of $14 million for
inventory write-downs associated with restructuring actions.

The Company is continuing the restructuring plan implemented in the
third quarter of 1998.  As of SeptemberMarch 26, 1999,2000, approximately $66$88 million
has been charged against the liabilities associated with these actions.
The Company has funded the restructuring actions using cash generated
from operations.  The remaining actions to be completed consist
primarily of the outsourcing of certain manufacturing operations and

     Year 2000:
     __________

The Company experienced no issues on the 9-9-99-date horizon.
Preparation for Year 2000 continues to be a priority for Cummins into
and after January 1, 2000.  While the Company substantially met its
goal of Year 2000 readiness by June 30, 1999, a few outstanding issues
remain.  Plans to resolve such issues are addressed below.

The Company's Year 2000 program is a centrally coordinated, enterprise-
wide effort which is carried out by the Company's Year 2000 Program
Office under the leadership of the Director of the Year 2000 Program.
The Year 2000 program is implemented at each of the Company's
facilities and is overseen by a Year 2000 coordinator assigned to each
site.  The Company's Year 2000 Program Office monitors the progress and
compliance of its facilities through audits and reports by the Year
2000 coordinators.  In addition to internal resources, the Company
continues to retain external resources to assist with its Year 2000
program.  The Company believes that it is taking full advantage of its
internal resources and all necessary external resources to understand,
identify and correct all Year 2000 issues within its control.

The Company's Year 2000 program involves:
1) mainframe (legacy systems); 2) distributed computing (includes
manufacturing and warehousing systems, end user computing, facility
systems, laboratory equipment, technical infrastructure and remote
business systems); 3) products; 4) suppliers; 5) business readiness and
contingency planning; and 6) communication.  The general phases of the
program are: a) inventory; b) analyze and prioritize; c) determine
compliance; d) remediate, replace or retire and e) test, implement,
audit and maintain.

 12
Mainframe, Distributed Computing:
The Company completed the inventory, analysis and prioritization phases
of its mainframe and distributed computing in 1998.  The inventory
process led to the packaging of mainframe programs into remediation
groups to facilitate testing.  Testing began in 1998 and will continue
through 1999.  Quality assurance checks resulted in the review, repair,
testing and re-installation of some programs.  Tests of software
applications using the 9-9-99 and 1-1-2000 dates were successfully
executed.  Some outstanding issues remain.  About 5 of the Company's
142 sites continue to address Year 2000 issues.  One issue involves the
"ALPS" (Aftermarket Logistics and Planning System) software program
used by the Company's aftermarket and distributor locations.  The
outstanding issues are known and monitored.  The remainder of the year
will be used to address these and any other outstanding issues that
emerge, and also to complete related contingency plans.  The Company
will use its best efforts to ensure that any outstanding Year 2000 item
will be completed before the end of 1999.

Products:
During
the first quarter of 1999, the Company announced that its
commercial products met the Company's Year 2000 compliance standards.
A postingdue to Brazilian currency translation losses
and losses on the Company's Internet website provides this information
to customers and other stakeholders.

Suppliers:
The greatest area of potential risk is the supply chain.  This is
particularly true because the Company utilizes global, sole suppliers
for certain critical components usedvarious asset dispositions recorded in the manufacturefirst quarter
of the
Company's products.  The high level of skill and expertise required to
develop certain components makes it impractical and sometimes
impossible to change such suppliers quickly.  The failure of a sole
supplier may lead to a delay in production and/or business
interruption.  To mitigate this potential risk, the Company initiated a
global effort in 1997 to evaluate its business critical suppliers.  The
Company continues its efforts to review the Year 2000 readiness of key
suppliers through a formal program of prioritization and communication
using questionnaires and/or follow up contacts, as appropriate.  To
further the Company's efforts with suppliers, the Company continues to
be a member of the Automotive Industry Action Group (AIAG).  The
Company completed the identification of high-risk suppliers in April
1999 and has continued to update this information as additional AIAG
surveys are completed.  Using survey data and other input where
required, the Company has developed contingency plans1999.

that have been identified as "high-risk."Income Taxes:
     __________________________

The Company's plants are
also developing site-specific contingency plans for critical suppliers.

Business Readiness and Contingency Planning (BRCP):
As previously stated, the Company believes that its "reasonably likely
worst case scenarios" may involve the failure of third parties with
whom the Company does business to address Year 2000 issues.  As a
result, the Company is taking steps to minimize the impact of its
exposure to Year 2000 risks outside its control.  The objective of our
BRCP is to assure that the Company retains the ability to sustain
acceptable operations despite the Year 2000 failures of third parties
or failures induced by them.  The process for BRCP is process design,
business impact analysis, contingency planning and auditing, testing
and monitoring.  Our model is consistent with the recommendations of
the U.S. General Accounting Office.  In the following months, the
Company will finalize its business readiness and contingency planning
to address possible external Year 2000 problems.  A significant part of
this effort has been the evaluation of the risk to the Company's
operations from external sources, and the development of strategies to
manage those risks.  The Company's efforts in this regard include
identifying alternate suppliers, setting up work-arounds and adjusting
inventory levels.  The Company's contingency planning also covers the
identification and evaluation of risk areas at the Company's
international locations and international independent distributors,
particularly at countries that have been identified as behind in their
Year 2000 readiness efforts.  The Company is providing information on
country and industry risk to its international locations, and is also
considering country riskincome tax provision in the developmentfirst quarter of its contingency plans.
Contingency plans will also address any potential internal issues that
may arise.

 13
Communication:
The Company continues to receive and respond to customer inquiries
regarding the general Year 2000 readinesswas $17
million, reflecting an effective tax rate of the Company, and the Year
2000 compliance of the Company's commercial products.  The inquiries
and responses take the form of telephone calls, written communication
and electronic mail.  For the convenience of its customers, the Company
maintains a Year 2000 Internet website at www.cummins.com/custasis/y2k.html.
The Company's product compliance information is also included on that
website.  The Company also maintains an Intranet Year 2000 website27 percent for the use of its employees.

Costs of Company's Year 2000 issues:
The Company expects to incur total expenditures of approximately $45
million in connection with its Year 2000 program and remediation
efforts.  The Company is funding its Year 2000 costs with cash flows
from operations.  To date, the Company has incurred  $42 million in
costs relating to its Year 2000 efforts.  The Company has forecasted a
temporary increase in inventory levels per year-end contingency plans
for high-risk suppliers.

There can be no assurances that the systems or products of third
parties relied upon by the Company, such as suppliers, vendors or
significant customers, will be timely converted or that a failure by
such third parties, or a conversion that is incompatible with the
Company's systems, would not have a material adverse effect on the
Company.  Other undiscovered factors related to the Year 2000 issue may
also have potential for an adverse effect on the Company. Such adverse
effects may include an adverse effect on the Company's revenues.  The
estimated time of completion and success of the Company's Year 2000
program and compliance efforts, and the expenses related to the
Company's Year 2000 compliance efforts are based upon management's best
estimates, which were based on assumptions of future events, including
the availability of certain resources, third party modification plans
and other factors.  There can be no assurances that these results and
estimates will be achieved, and the actual results could materially
differ from those anticipated.  Specific factors that might cause such
material differences include, but are not limited to, the availability
of trained personnel, the ability to locate and correct all relevant
computer code, and the failure by third parties to address their Year
2000 problems.year.
