Detailed Product Description

Hayden 2739 is an engine cooling fan clutch engineered for thermal control in reverse-rotation cooling fan systems. It uses a standard-duty thermal design and a flange mount with four bolt holes and M10 x 1.5 hole thread specification. Key dimensions include a 7.2-inch clutch maximum diameter, 3.25-inch fan bolt circle, 2.43-inch mount diameter, 1.75-inch distance from clutch to mounting flange, and 3.33-inch overall height. The aluminum construction and non-electronic layout make it a straightforward replacement for service applications that call for a conventional thermal fan clutch.
