Apparatus, systems, and methods for engine dowel installation

A method of fabricating holes in a locomotive engine, the method including the steps of:

• selecting either a conductor-side jig configured to accommodate locomotive components on a conductor-side of a locomotive engine or an engineer-side jig to accommodate locomotive components on an engineer-side of a locomotive engine;
• coupling the selected drill jig having a first member and a second member with a plurality of openings, to a base of the corresponding side of the locomotive engine, wherein the first member is located a pre-determined distance above the second member and the second member is configured to engage the engine base, wherein the second member includes a jig bolt hole configured to overlay an engine mounting bolt hole;
• providing multiple locations via the plurality of openings in which a dowel hole can be drilled into the engine base;
• coupling a bushing having a cavity configured to receive a drill bit with a first opening in the second member;
• and
• drilling at least one dowel hole in the engine base via a drill positioned on the second member.
