     Re: Coltec Capital Trust
 
Ladies and Gentlemen:
 
     We have acted as special Delaware counsel for Coltec Industries, Inc., a
Pennsylvania corporation (the "Company"), and Coltec Capital Trust, a Delaware
business trust (the "Trust"), in connection with the matters set forth herein.
At your request, this opinion is being furnished to you.
 
     For purposes of giving the opinions hereinafter set forth, our examination
of documents has been limited to the examination of originals or copies of the
following:
 
          (a) The Certificate of Trust of the Trust, dated as of April 8, 1998
     (the "Certificate"), as filed in the office of the Secretary of State of
     the State of Delaware (the "Secretary of State") on April 8, 1998;
 
          (b) The Declaration of Trust of the Trust, dated as of April 8, 1998,
     by and among the Company and the trustees of the Trust named therein;
 
          (c) The Amended and Restated Declaration of Trust of the Trust, dated
     as of April 14, 1998 (including Annex I and Exhibits A-1 and A-2 thereto)
     (the "Declaration"), among the Company, as sponsor, the trustees of the
     Trust named therein, and the holders, from time to time, of undivided
     beneficial interests in the assets of the Trust;
 
          (d) Amendment No. 1 to the Registration Statement on Form S-3 (the
     "Registration Statement"), including a preliminary prospectus (the
     "Prospectus"), relating to the 5.25% Trust Convertible Preferred Securities
     of the Trust representing undivided beneficial interests in the assets of
     the Trust (each, a "Preferred Security" and collectively, the "Preferred
     Securities"), as proposed to be filed by the Company and the Trust with the
     Securities and Exchange Commission on or about July 14, 1998; and
 
          (e) A Certificate of Good Standing for the Trust, dated July 14, 1998,
     obtained from the Secretary of State.
 
     Initially capitalized terms used herein and not otherwise defined are used
as defined in the Declaration.
 
     For purposes of this opinion, we have not reviewed any documents other than
the documents listed in paragraphs (a) through (e) above. In particular, we have
not reviewed any document (other than the documents listed in paragraphs (a)
through (e) above) that is referred to in or incorporated by reference into the
documents reviewed by us. We have assumed that there exists no provision in any
document that we have not reviewed that is inconsistent with the opinions stated
herein. We have conducted no independent factual investigation of our own but
rather have relied solely upon the foregoing documents, the statements and
information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.
 
     With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.
 
     For purposes of this opinion, we have assumed (i) that the Declaration
constitutes the entire agreement among the parties thereto with respect to the
subject matter thereof, including with respect to the creation, operation and
termination of the Trust, and that the Declaration and the Certificate are in
full force and effect and have not been amended, (ii) except to the extent
provided in paragraph 1 below, the due creation or due
   2
 
organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are parties to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (v) the due authorization, execution and delivery by all parties
thereto of all documents examined by us, (vi) the receipt by each Person to whom
a Preferred Security was issued by the Trust (collectively, the "Preferred
Security Holders") of a certificate substantially in the form of Exhibit A-1 to
the Declaration, in accordance with the Declaration, and as described in the
Registration Statement, and (vii) that the Preferred Securities were issued to
the Preferred Security Holders in accordance with the Declaration, and as
described in the Registration Statement. We have not participated in the
preparation of the Registration Statement and assume no responsibility for its
contents.
 
     This opinion is limited to the laws of the State of Delaware (excluding the
securities laws of the State of Delaware), and we have not considered and
express no opinion on the laws of any other jurisdiction, including federal laws
and rules and regulations relating thereto. Our opinions are rendered only with
respect to Delaware laws and rules, regulations and orders thereunder that are
currently in effect.
 
     Based upon the foregoing, and upon our examination of such questions of law
and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:
 
          1. The Trust has been duly created and is validly existing in good
     standing as a business trust under the Business Trust Act.
 
          2. The Preferred Securities have been duly authorized and are validly
     issued and, subject to the qualifications set forth in paragraph 3 below,
     fully paid and nonassessable undivided beneficial interests in the assets
     of the Trust.
 
          3. The Preferred Security Holders, as beneficial owners of the Trust,
     are entitled to the same limitation of personal liability extended to
     stockholders of private corporations for profit organized under the General
     Corporation Law of the State of Delaware. We note that the Preferred
     Security Holders may be obligated to make payments as set forth in the
     Declaration.
 
   
     We consent to the filing of this opinion with the Securities and Exchange
Commission as an exhibit to the Registration Statement. In addition, we hereby
consent to the use of our name under the heading "Legal Matters" in the
Prospectus. In giving the foregoing consents, we do not thereby admit that we
come within the category of Persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.
    
 
                                          Very truly yours,
 
                                          RICHARDS, LAYTON & FINGER, P.A.
