This manual contains descriptions and maintenance instructions for field and sustainment maintenance levels for
the Engine, Model 8V92TA.
Type of Manual: Field and Sustainment Maintenance Manual.
Purpose of Equipment: The engine is a Detroit Diesel 8V92TA and is the source of power for propulsion and
maneuverability. The engine is the first component of the drivetrain which consists of a marine gear, transfer
case, and pump-jet, which is connected by driveshafts.
MAINTENANCE FORMS, RECORDS, AND REPORTS
Department of the Army (DA) forms and procedures used for equipment maintenance will be those prescribed by
DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual; or
Army Regulation (AR) 700-138, Army Logistics Readiness and Sustainability.
REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR)
If your engine needs improvement, let us know. Send us an EIR. You, the user, are the only one who can tell us
what you don't like about your equipment. Let us know why you don't like the design or performance.
ALL non-Aviation/Missile EIRs and Product Quality Deficiency Report (PQDRs) must be submitted through the
Product Data Reporting and Evaluation Program (PDREP) web site. The PDREP web site is: https://
If you do not have Internet access, you may submit your information using an SF 368 (PQDR). You can send your
SF 368 using e-mail, regular mail, or fax using the addresses/fax numbers specified in DA PAM 750-8. We will
send you a reply.
CORROSION PREVENTION AND CONTROL (CPC)
Corrosion prevention and control 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 items. The term "corrosion" means the deterioration of a material or its properties
due to a reaction of that material with its chemical environment. An example is the rusting of iron. Corrosion
damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface residue, and/or
cracking. Plastics, composites, and rubbers can also degrade (also considered to be corrosion based on the
above definition of corrosion). Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents),
or photolytic (light, typically ultraviolet) processes. The most common exposures are excessive heat or light.
Damage from these processes will appear as cracking, softening, swelling, and/or breaking. The US Army has
defined the following nine (9) forms of corrosion used to evaluate the deterioration of metals. These shall be used
UNIFORM (or general attack): Affects a large area of exposed metal surface, like rust on steel or tarnish on silver.
It gradually reduces the thickness of the metal until it fails.
CREVICE: Occurs in crevices created by rubber seals, gaskets, bolt heads, lap joints, dirt or other surface
deposits. It will develop anywhere moisture or other corrosive agents are trapped and unable to drain or
SELECTIVE LEACHING: One element, usually the anodic element of an alloy, corrodes away, leaving the
cathodic element. This can create holes in metal.
