This Technical Manual TM 5-4930-200-20 covers the Gray Model 251-325 and Gray Model 251-315 Lubricating and Servicing Unit, identified under FSN 4930-857-7160 and FSN 4930-064-6887, and is dated August 1963. For collectors of U.S. Army technical manuals, military maintenance equipment references, Cold War support-system literature, and dated government publications, this is a strong period document tied to a specialized category of Army field-service equipment.
Because this is a -20 technical manual, it belongs to the organizational maintenance side of Army documentation. In practical terms, manuals in this category were intended to support inspection, servicing, adjustment, repair, and maintenance procedures at the unit level. That gives this publication more technical value than a simple operator reference and makes it especially useful for collectors, researchers, and restorers who want original service-era documentation.
The Gray Model 251-325 & 251-315 Lubricating and Servicing Unit
The Gray Model 251-325 and Gray Model 251-315 Lubricating and Servicing Unit belong to the broader family of military maintenance, lubrication, and field-support equipment. As identified by their nomenclature, these were servicing units intended to support lubrication and related maintenance functions, placing them squarely in the support side of Army operations rather than in the category of conventional weapons or combat vehicles.
Equipment in this class was associated with keeping vehicles, machinery, and support equipment properly serviced in field and shop environments. In military use, units like these were relevant to motor pools, maintenance sections, engineer units, and general support operations where dependable lubrication and servicing capability was essential to keeping equipment operational.
For collectors, that makes this manual especially interesting because it documents the technical side of Cold War military maintenance equipment rather than more commonly seen combat hardware. It also has strong crossover appeal for anyone interested in military shop equipment, lubrication systems, and U.S. Army support infrastructure. The inclusion of FSN 4930-857-7160 and FSN 4930-064-6887 adds cataloging value for collectors who prefer manuals with specific government stock-number references rather than only general nomenclature.
What This Manual Covers
As an organizational maintenance technical manual, TM 5-4930-200-20 would have been intended to support the service and upkeep of the Gray Model 251-325 and Gray Model 251-315 Lubricating and Servicing Unit at the unit-maintenance level.
In practical terms, a manual like this is especially relevant for:
- nomenclature and identification
- maintenance and servicing guidance
- inspection and adjustment procedures
- repair and troubleshooting reference
- organizational maintenance information
- archival and restoration research use
That makes it useful not only as a collectible, but also as a practical reference for anyone studying how the Army maintained lubrication and servicing equipment during the early Cold War period.
Historical Significance
The date August 1963 places this publication in the early Cold War period, when the U.S. military maintained extensive technical literature covering not only weapons and vehicles, but also the maintenance equipment required to keep those systems serviceable. Manuals like this reflect a period when Army documentation extended into every part of the logistical chain, including lubrication gear, servicing equipment, maintenance tools, and field-support systems.
For collectors and historians, this manual is especially relevant to subjects such as:
- Cold War U.S. Army technical manuals
- military maintenance and servicing equipment
- lubricating units and motor-pool support systems
- Army organizational maintenance documentation
- dated military technical publications
Because it covers specialized servicing equipment rather than a more common tactical vehicle or weapon system, it also adds variety to collections that already include standard ordnance or maintenance manuals.
About This Manual
