The dowel pin, part number 205129, serves as a precision alignment component in various mechanical assemblies. Its primary function is to establish an exact reference position between two or more parts, preventing relative movement and ensuring that components are joined according to their design specifications. In addition to maintaining alignment, these pins are engineered to support shear loads within the assembly.

This component is designed for use in Cummins engines. Within these power units, dowel pins are employed in critical locations such as the interface between the engine block and cylinder head, as well as for the alignment of the oil pump, water pump, or flywheel housing. Proper seating of these pins is necessary to prevent undue stress on surrounding engine components.

Dowel pins function by providing a rigid mechanical link that constrains the movement of joined parts. By maintaining tight tolerances, they ensure that rotating or stationary assemblies remain centered, which is necessary for the proper operation of internal engine systems. During engine maintenance or rebuilds, these pins are used to restore the original factory alignment of the assembly.
