NAVFAC P-300 Management of Transportation Equipment

(b) During and After Retreading. As set forth in paragraph 4.1 of
ZZ-T-441H, the Government reserves the right to perform any of the inspections as
provided in the specification for compliance with prescribed contract requirements. A
representative of the user activity should establish the inspection procedure with the
Contracting Officer in order that quality checks of the contractor’s plant can be
arranged. A visit to the retreading plant to observe craftsmanship, process controls,
condition of processing equipment, quality of the rubber used, and cleanliness of the
shop provides the necessary confidence level for quality assurance. When the
retreaded tires are returned to the user, the activity's representative who has become
familiar with the contractor's retreading process should inspect each tire. Retreaded
tires found to be defective should be returned to the contractor (at the contractor's
expense) for corrective action. Activity inspections shall verify that the newly delivered
retreaded tire is on the original Navy casing. Also, additional visual inspections are to
be performed as outlined in Tables II and III of Specification ZZ-T-441H, to determine
any defective material used, poor processing, or poor workmanship.
c. Tire Marking/Identification. Tire labeling of ownership shall be established
by user activities in the following areas:
(1) On tire casings furnished to a contractor for retreading/repair service.
(2) On popular size tires under specific conditions.
(a) To improve local control and accountability.
(b) As a deterrent to pilferage.
Tire labeling/marking shall be by either patch or branding for permanent identification
and shall be made up of enough lettering to spell out "USN activity". This label is to be
located on or into the area of the tire side wall (but not in the scuff ribs) and shall not
interfere with other DoT required markings. Branded letters shall be approximately
1/16 to 1/8 inches deep, measured from the surface immediately surrounding the
lettering.
4-1.11 Preventive Maintenance Procedures For Construction And Allied
Equipment (Less Weight Handling Equipment)
4-1.11.1 General. Preventive maintenance (PM) principles and general procedures set
forth in paragraphs 4-1.9 through 4-1.13 are equally applicable to all construction
equipment. (See the NAVFAC P-307 for weight handling equipment.) Maintenance
inspections and services shall be performed as prescribed by the manufacturer in the
maintenance manual provided with the equipment and at the recommended
frequencies. The frequencies shall generally be based on hours of operation as
recorded on an hour meter, rather than fixed time intervals, except for the daily services
performed by the operator.
