A machine is provided including a frame and at least one track, such as first and second ground engaging tracks, coupled with the frame. A plurality of pins are provided which each couple together at least two of the links of the tracks and include an outer diameter, a first end and a second end. The first and second ends of the pin may be press fit in first and second bores of first and second links of the tracks, respectively. A non-directional surface finish along a first portion of the length of the pin within the first bore forms a fluid seal with the first bore, whereas a directional surface finish along a different portion of the length of the pin within the first bore inhibits removal of the first end of the pin from the first bore. A method of coupling together machine components via an enhanced press fit is further provided, utilizing a pin having a first surface finish configured to form a fluid seal with a bore of a machine component, and a second surface finish configured to inhibit removal of the pin from the bore.
