Caterpillar Dowel Pin 1F5151

1F5151 is a headless cylindrical dowel pin used to locate adjacent engine or machine components and maintain their relative position during assembly. The pin is intended for Caterpillar equipment, including Caterpillar engines and machines listed below. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The dowel pin is installed by press-fitting one or both ends into the mating components. Its controlled cylindrical diameter allows it to transfer load between the connected parts and keep the components aligned. The part is supplied as a single dowel pin unless the applicable parts list specifies otherwise.
