Clutch, Fan, Engine

The Defense Logistics Agency Land and Maritime is seeking sources for engine fan clutches (NSN 2930-01-668-5049) used in the Heavy Equipment Transporter (HET) system, specifically the M1070 truck and M1000 trailer combination employed for transporting tanks and heavy military equipment. This Pre-Solicitation Notice (Sources Sought Notice 2025-SPRDL125R0159) is not an open solicitation but rather an opportunity to qualify as an approved source for future competitive solicitations. The fan clutch is a temperature-regulating component that intelligently controls engine cooling by increasing fan speed when the engine is hot and decreasing it when cooler, thereby optimizing performance, reducing fuel consumption, and minimizing engine wear. Qualification testing and evaluation are mandatory requirements to become an approved source, and interested firms must submit a Source Approval Request (SAR) Package to the Source Approval Officer at usarmy.detroit.tacom.mbx.mso-ombudsman@army.mil. The deadline for submissions is November 21, 2025, and prospective suppliers should note that source approval does not guarantee future contract awards but provides only the opportunity to compete on subsequent solicitations.

This opportunity carries no set-aside designations and is open to all qualified suppliers. The government requires between 60 and up to 1,483 units of the clutch, with the exact quantity to be determined through future procurement actions. No incumbent contractor or current supplier information is identified in this notice. While no specific award value or budget range is disclosed in this Pre-Solicitation Notice, the quantity range and criticality of the component for military transport operations suggest a potentially significant contract opportunity. Interested parties should contact the Source Approval Program office at TACOM for detailed SAR package requirements and additional guidance on the qualification and approval process.
