Preservation of Engines (Gasoline and Diesel) - Issue 4: 10/2015
 N DEF STAN 81-70

Annotation

This Standard specifies methods of preservation used in Military Level Packaging, in accordance with Def Stan 81-41, of gasoline and diesel engines configured with a metering fuel pump. It is complementary to the current Services Packaging Instruction Sheet, (SPIS); see also Def Stan 81-41 (Part 4).

This standard does not cover the following:

a) Aircraft engines,

b) Diesel engines incorporating individual injector metering pumps (identified by a single fuel line, 'common rail', from pump to injector(s) / rocker cover).

Where long term preservation, as defined by Def Stan 81-41, is required and there is no suitable long term preservation for internal channels then the following procedure may be used. The preservation procedure shall use the normal operating fluid as the preservative, unless otherwise specified by the SPIS. The engines shall then be packaged in a fully desiccated pack as per Def Stan 81-41, with internal channels 'dry' having been drained of all preservative substances.

This standard may not be suitable for items designated as short-term storage items, e.g. to be used within one year after receipt or be re-commissioned in the field.
