2. Model Numbers and Equipment Names. Tractor-Dozer, Self-Propelled Crawler, Diesel Engine Driven
(DED), Model D6K Type I with Winch, or Model D6K Type II with Ripper.
3. Purpose of Equipment. The D6K Dozer is an earth-moving machine with a bulldozing attachment that cuts,
moves, and grades material through forward motion of the machine. Additional attachments include a ripper
and a towing winch, which are used to exert a push or pull force. Mission support role includes construction
and maintenance of roads, airfields, hardstands, drainage, and site preparation for pipeline and river crossing.
MAINTENANCE FORMS, RECORDS, AND REPORTS
Department of the Army forms and procedures used for equipment maintenance will be those prescribed by (as
applicable) DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual; or AR 700-138,
Army Logistics Readiness and Sustainability.
REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR)
If your D6K Dozer needs improvement, let us know. Send us an EIR. You, the user, are the only one who can
tell us what you do not like about your equipment. Let us know why you do not like the design or performance.
All non-Aviation/Missile EIRs and PQDRs must be submitted through the Product Data Reporting and
Evaluation Program (PDREP) Web site. The PDREP site is: https://www.pdrep.csd.disa.mil/
If you do not have Internet access, you may submit your information using an SF 368 (Product Quality
Deficiency Report). You can send your SF 368 using email, regular mail, or fax using the addresses/fax
numbers specified in DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual.
We will send you a reply.
CORROSION PREVENTION AND CONTROL (CPC)
1. CPC of Army materiel is a continuing concern. It is important that any corrosion problems with this item be
reported so that the problem can be corrected and improvements can be made to prevent the problem in future
2. Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of
metals. It is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of
iron. Corrosion damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface
3. Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat) energy,
oxidation (oxygen), solvation (solvents), or photolytic (light, typically UV) processes. The most common
exposures are excessive heat or light. Damage from these processes will appear as cracking, softening,
swelling, and/or breaking.
4. SF Form 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM
750-8, TAMMS Users Manual.
